Great area! Many shops and restaurants nearby. Zoe was a great hostess!
Right size ,clean. well equipped, great location near Atlantic terminal. Many restaurants and shops in the neighborhood.
Owners hospitable and helpful.
It was a pleasure.
Zoe's Fort Greene studio was exactly as I had hoped - comfortable, cozy, and located perfectly for easy public transport access to Manhattan, other parts of Brooklyn, and JFK. The apartment is located about a 2 minute walk from Atlantic terminal, a major subway hub, which made transport easy and inexpensive. The studio is tidy and comfortable, with a wonderful bed. The kitchen has a full-sized gas stove and oven, which I used to make breakfast. It was incredibly cold during my stay, but the heating was excellent. Zoe was also very kind and flexible regarding my check-out, which was much appreciated and made for a more relaxing and productive day. There are plenty of restaurants nearby, and a couple of small grocers, including organic stores with delicious prepared foods. I would be happy to stay again!
I arrived during a cold, gray time in NYC, and this place was the perfect antidote--warm and full of daylight and little details that made it feel homey after long days out in the icy slush. Very clean and charming, this studio was a great landing spot. It's near all the subways and lots of sweet shops and restaurants. The bed was very comfortable, and Zoe couldn't have been nicer. Highly recommend!
We stayed in Zoe's studio suite for 3 nights in October. We had stayed in Manhattan prior to that for a few days and we really enjoyed Brooklyn. This apartment is very close to a main Subway Station that will take you anywhere in Manhattan. The Park Slope area and Prospect park are both easy walks from the apartment and Williamsburgh is about a 10-15 minute cab ride. The apartment is in an old building but the suite itself is pretty much what you see in the pictures. It was great for a couple but would be tight with any more than 2 people. We would definitely stay here again. Zoe was very easy to deal with and nice to meet in person. Thanks Zoe!
My husband and I travelled to America for the first time on our first big trip without the kids. We decided to try vrbo and couldn't have been happier. We were thrilled with this studio in Brooklyn. From the outset negotiating the booking and payment was relaxed and easy and Zoe was a delight to deal with. She greeted us with warmth and made herself available to help or answer any questions. The studio is decorated with love and attention to detail. The bed was super comfy and the deck was a real highlight. Whenever we were home we sat outside and soaked in the sunshine and watched the world go by. Close to shops, wine bars and restaurants and in a lovely part of town this studio is perfectly located and an easy walk to numerous subways. My husband and I are runners and found it an easy jog across the Brooklyn Bridge into Manhattan. We spent a magical night in Brooklyn Bridge park watching the lights come on in Manhattan- a must do. We thoroughly recommend this studio.
We are located at the best possible location in terms of subway train access with 14 subway lines all within 1 block. Manhattan is just a 10-minuet ride away or you can enjoy one of New York's best and most vibrant neighborhoods right at your doorstep, Fort Greene!

A former crime reporter, political writer and investigative journalist, I'm now a full-time novelist.
I've never done anything much for a living except write. In my deep and distant past, I worked for several US newspapers, including the Savannah Morning News and the Dallas Morning News. For a few years I was a stringer for Reuters in New Orleans, where I survived three hurricanes and countless dodgy politicians.
In addition, I've written several books about travel in Paris and Ireland for Time Out and Frommers.
For a while, I even worked for the British government.
But that's another story.
Night School was my first novel. The Night School series has been translated into twenty-two languages so far.
(Need a biography to copy and paste for an upcoming event or publication? Click here.)
Press interviews
I link to lots of interviews on my Press page.
Your questions answered
Here's a short video interview in which I answer questions sent in to me by Night School fans. See the real boarding school that started it all.
A Night School movie
There is no film deal for the Night School books yet. I'd love for it to happen but the right deal hasn't come along. I get asked a LOT who I would want to be in such a film were it to happen.
Find out my thoughts in an interview I did with Maximum Pop.
And then watch the Night School Web Series on my YouTube channel!
All you need to know about me
I like coffee, tacos, red wine, Buffy, Game of Thrones, Dorothy Parker, F Scott Fitzgerald, the 1920s in general, Champagne, Firefly, and reading, reading, reading…
I hate flying, night clubs, traffic jams and leaf blowers.
I write in my home in the south of England, where I live with my husband, the filmmaker Jack Jewers (who makes my book trailers), and a small, easily irritated menagerie of pets.

Oven-Smoked Kalua Pork
Total Time
Prep 10 mins
Cook 3 hrs
Fire up the tiki torches and pour yourself a mai tai! This is a take-off on Hawaiian pit-cured pork, smoky and a little salty, and done easily in your oven! At first I was a little worried about cooking the pork at such a high temperature for so long, but it comes out perfectly.
Ingredients Nutrition
- 3 1⁄2 lbs pork roast, trimmed of fat
- 2 cups water
- 1 teaspoon liquid smoke
- 3 tablespoons kosher salt
- Preheat oven to 400 degrees F.
- Place pork roast fat side up in a roasting pan.
- Combine Liquid Smoke and water and pour over meat.
- Sprinkle kosher salt on top of meat; cover and cook at 400 degrees F for three hours, or until meat is done.
- Let cool slightly, then shred.
Most Helpful
I have a similar version to this recipe. First I make cuts in the meat all the way around and rub the salt into the slits. Then I rub the meat with liquid smoke. I seal the meat in foil before placing it in the roasting pan. It always comes out juicy.
This recipe was easy and the pork came out super tender and delicious! <br/>I cut several slits in the 4 pound pork butt, then used 2 Tablespoons of Hawaiian salt, 2 to 3 Tablespoons of Liquid Smoke, and some Da Kine Smoked Flavor Dry Rub. I set the oven for 500 for the first 30 minutes then lowered it to 300 after that. After wrapping the pork in foil I didn't check on it at all until the timer went off 5 hours later and was pleasantly surprised with the results!
Fabulous- so easy too! Based on the advice of a friend I did add 1 tsp grated ginger and changed the liquid smoke (I used mesquite flavor rather than hickory) to about 3 Tbs and I served this on Kings Hawaiian rolls...the so-yummy, slightly sweet taste perfectly complemented the smoky, slightly salty pork. I will be making this at our next family gathering. Thanks so much for posting!

Still smarting from Thursday's black eye in Philadelphia, the St. Louis Blues on Friday found solace. Defenseman Kevin Shattenkirk was on the ice with the team, along with trade deadline pickup Zbynek Michalek.
Shattenkirk, an all-star defenseman with key offensive skills, hasn't played since an abdominal injury on Feb. 1 that required surgery. Friday was his first time on the ice with teammates.
MORE: Jets' Byfuglien injured | Preds' Forsberg rising | Leafs' Kessel unloads on media
Michalek was acquired from the Phoenix Coyotes in one of three depth deals the Blues made. He, too, is in recovery mode — officially an upper-body injury reports indicate was a concussion.
Once both are healthy, the Blues will have one of the strongest defense corps in the Western Conference.
The Blues are in Toronto to face the Maple Leafs on Saturday as they continue their pursuit of the Nashville Predators in the Central Division. They are four points behind the Preds with two games in hand but have a spate of road games this month. They also are six points behind Western Conference leader Anaheim.
"It's good to get on the ice again. I haven't skated for free weeks, so it's nice to feel like a hockey player again," Michalek told Blues writer Chris Pinkert. "It's a good day and hopefully the rest of the day goes well for me, too, and I can get back on the ice tomorrow and do more."
Coach Ken Hitchcock said neither player has a target date for returning to action.

Shattenkirk has eight goals and 32 assists in 49 games, and he is among the Blues' top shootout players. Michalek is expected to help in his own zone, where the Blues often have trouble because of turnovers.
Thursday's 3-1 loss to the Flyers marked the second time this season the Blues lost in regulation after entering the third period with a lead.

XML schemas convey the data syntax and semantics for various application domains, such as business-to-business transactions, medical records, and production status reports. However, these schemas seldom address security issues, which can lead to a worst-case scenario of systems and protocols with no security at all. At best, they confine security to transport level mechanisms such as secure sockets layer (SSL). On the other hand, the omission of security provisions from domain schemas opens the way for generic security specifications based on XML document and grammar extensions. These specifications are orthogonal to domain schemas but integrate with them to support a variety of security objectives, such as confidentiality, integrity, and access control. In 2002, several specifications progressed toward providing a comprehensive standards framework for secure XML-based applications. The paper shows some of the most important specifications, the issues they address, and their dependencies.

Publisher's Description
Did God give us a formula for motherhood?
Constant pressure to live up to unrealistic ideals can lead women to serious problems like depression, says Carla Barnhill in her interview with Jane Johnson Struck for CHRISTIAN PARENTING TODAY. Barnhill believes the role of motherhood has been undervalued and over romanticized by our culture and our church, leading mothers to feel overwhelmed by expectations, unsure of their parenting skills, and burdened by a sense of failure.
Why is it essential to differentiate between God s leading in parenting and our desire to please others by fulfilling idealistic expectations? How can we gain contentment in our role as mothers? Why should recognizing the truth that God has created us all uniquely and has a different function for every individual and family free us from social norms?

I have a Android Air project written in AS3, when the project starts I am loading the music and loading the XML file to be parsed. In the first frame I call my classes to parse the XML and set the nodes at strings, and to play the audio, these both work fine. Also in my first frame I am declaring some textfields to input the data from the XML file so that when the user enters frame 3 the user is able to see this data from the XML file. This also works fine. The problem I am having is going between frame 4 and back to frame 3, the data in the textfields disapears? I trace the strings from the XML class that are holding the data and these values appear everytime, but going from frame 3 to frame 4 and back to frame 3 wipes out the textfield display? Can anyone point me in the right direction? thanks Scientific
Ok here is some code from frame one where I am declaring the textfields
var name1TextField:TextField = new TextField();
var name2TextField:TextField = new TextField();
var format:TextFormat = new TextFormat();
format.font = "_sans";
format.color = 0xF8FBF8;
format.size = 36;
//set the names format to the textfields
name1TextField.defaultTextFormat = format;
name2TextField.defaultTextFormat = format;
Here is the code calling the XML parsing class and setting the text to the nodes
var network:networkScores = new networkScores();
var timer4:Timer = new Timer(600);
timer4.addEventListener(TimerEvent.TIMER, scoresDis);
function scoresDis(e:TimerEvent):void
name1TextField.text = network.name1;
name2TextField.text = network.name2;
name1TextField.width = 230;
name2TextField.width = 230;
Previously above I had stated that I am calling the audio class and the xml class from the first frame, declaring the text fields and moving on from there. Now I have decided that since this XML file is a list of scores and coded be always changing, I thought it would be good to load and parse this file everytime I enter frame 3. The same thing is still happening, I have my scores display and then when I go to frame 4 and back to frame three, the scores do not display, but when I trace the data from the class, it displays properly. Thanks Scientific

The Escondido area in San Diego plays host to one of the sought after restaurants in the area, Bellamy's. Brian Bonar, a prominent figure in the financial sector, is the owner of the Escondido restaurant.
Gianina Pickens, Bonar's stepdaughter, is also at the helm of the restaurant's management where she is tasked with the role of overseeing the day-to-day operations.
Since a good restaurant must have a highly skilled chef, Brian Bonar entrusted Frenchman chef Patrick Ponsaty to be the master chef at Bellamy's.
Chef Patrick Ponsaty
Formerly, Chef Ponsaty worked at Rancho Bernardo Inn as the executive chef. During this time at the El Bizcocho, he tutored one of the top talents in the cooking industry, Gavin Kaysen.
A testament to his skills and prowess as a master chef was his ability to coach Kaysen, which allowed him to become third in the National Trophy of Cuisine and Pastry in Paris.
This propelled Kaysen into prominence and later taking up the position held by Ponsaty. Later on, Ponsaty made a move to other ventures such as MOF, Mistral at Loews, La Bastide as well as the Coronado Bay Resort among others.
His style of Cuisine, which he commonly refers to as French, boasts of chef Ponsaty's lyrical cooking and collection of vintage Armagnac. In 2012, his style of cooking earned him one of the most coveted titles in this field, Meilleurs Ouvrier de France. Learn more about Brian Bonar: http://www.whitepages.com/name/Brian-Bonar
He is one of the two individuals in San Diego, who holds such a title. Ponsaty is also among the ten persons in the whole of California with a similar distinction.
Brian Bonar
Brian Bonar is among the top renowned and successful business executives in the world. His business acumen stems out from his past leadership roles in various corporate entities such as Dalrada Financial Corporation.

ROBERT J. SCHWARTZ his ATTORNEYS United States Patent C) ABSTRACT OF THE DISCLOSURE A well bore logging system providing an analog output signal representing the acoustic travel time per unit distance over a longitudinal formation zone which may be greater than the longitudinal span defined between a pair of acoustic transducers. Electrical signals from one or more of the transducers are converted into digital signals that are successively entered into consecutive stages of a digital shift register in synchronization with movement of the well tool over predetermined depth increments. One or more of the signals stored in the stages of the shift register are selected and combined to provide an analog signal representing travel time measurement corresponding to a multiple of the span between the acoustic transducers.
This invention relates to logging systems useful in a Well conduit traversing earth formations for determining a characteristic property in the well conduit by means of a well logging tool. Specifically, the invention deals with improved systems of this type for obtaining indications of the property of the formations over a distance or longitudinal span different from the longitudinal measuring span associated with the well tool itself by means of digital processing. The invention also `deals with processing of digital signals relative to measurements in a well conduit.
It is now common practice to use the transmission of acoustic energy to log earth formations between an acoustic transmitter and one or more longitudinally spaced acoustic receivers carried by a logging tool. Depending on the properties of the formations, several different spans or spacing between the acoustic transmitter and receiver, or between one or more receivers, are used. For example, a large span or receiver spacing is employed where a smooth logging curve is desired. On the other hand, short receiver span measurements are usually implemented when a high degree of resolution is required.
At the present time, certain logging tools are equipped with acoustic receivers which have a fixed span of, for example, one or two feet, and this limits the length of the longitudinal formation zone which can be logged for each acoustic transmission. If a different span is required during a logging run, the tool must be lifted out of the borehole and exchanged for a tool outfitted to make acoustic measurements over the desired span. Another solution has been to employ a tool having one transmitter and two or more receivers spaced longitudinally in the tool at given intervals. With this type of tool, the span can be changed by selecting any one receiver or pair of receivers to obtain the :desired receiver spacing. In certain instances, however, practical considerations dictate that the distance between the various acoustic transducers located in the well tool remain fixed in order to achieve satisfactory logging results. In these situations, the above-described tool using two or more selectable receivers to change the receiver span is obviously unsatisfactory.
It is therefore among the primary objects of the present invention to provide improved logging systems in which a single logging tool may be used to obtain measurements corresponding to logging spans which are different from the fixed span of the logging tool.
Another object of the invention is to provide improved logging systems of the type described employing digital techniques for processing electrical logging signals.
A further object of the invention is to provide irnproved systems for procesing and combining successive electrical indications of a property of the logged formation.
A still further object of the invention is to provide system-s and apparatus for varying the effective logging span of a logging tool.
Yet, another object of the invention is to provide improved digital and simplified systems for processing digital logging signals.
Another object of the invention is to provide improved logging systems for obtaining information relating to the travel time of an acoustic signal thorugh borehole formations.
Briefly, these and other objects of the invention are obtained by selecting storing in a series of storage units successive electrical measurements from the acoustic transducers in the logging tool at a rate synchronized with the movement of the logging tool through the borehole. Certain of the electrical measurement signals are stored and advanced consecutively through the storage units under control of a signal related to movement of the logging tool, and the rate of storage of such signals may be substantially less than the rate at which consecutive measurements are produced by the acoustic transducers. Those measurements that are not selected for storage can be discarded. The stored electrical measurelments produced at positions of the logging tool separated by a distance corresponding to the span defined between two or more acoustic receiver-s are then sampled, preferably successively, and combined to generate an analog output signal, which may have a value representing the average of the sampled measurements. Preferably, the electrical measurements are in digital form and are stored in a register having a number of stage-s exceeding the number of electrical measurements that are sampled in any given sequence.
In a preferred embodiment, the system is employed for measuring the travel time of acoustic energy over a longitudinal formation zone greater than the span between a pair of receivers, and the sampled electrical indications each represent the formation travel time of the acoustic energy at successive positions of the logging tool separated by distances equal to the receiver span. Also, the sampled electrical indications are combined in such a manner that the output signal is representative of the average travel time per receiver span. For expedience, sampling of the electrical indications may be carried out at a rate substantially greater than the rate of storage of successive electrical indications, and the sampled electrical indications, if in digital form, fed through a digital-analog converter. The analog signals corresponding to the sampled electrical indications may then be conveniently averaged by recording them with recording apparatus having a response time substantially less than the sampling cycle time.
For a better understanding of the invention, together with the further aspects, objects, and advantages thereof, reference may be made to the following detailed description, taken in conjunction with the accompanying drawings, in which:
FIGURE l is an electrical block diagram of a logging system in accordance with the invention;
FIGURE 2 is an electrical block diagram of a portion of the apparatus included in the FIGURE l system;
FIGURE 3 is an electrical block diagram of another portion of the apparatus shown in the FIGURE 1 system;
FIGURE 4 is a graph of representative electrical signals helpful in explaining the operation of the apparatus shown in FIGURE 3;
FIGURE 5 is a graph of electrical waveforms useful in understanding the operation of a portion of the FIG- URE l system; and
FIGURE 6 is a block diagram of apparatus usable with the present invention.
For convenience, the invention will be described in connection with the measurement of travel time of acoustic tanrsducers. In FIGURE 1, a logging tool 10 is supported by an armored electrical cable 12 for passage through a borehole 14, which may be filled with a drilling fluid 16. The tool 10 includes an electroacoustic transmitter T for transmitting acoustic energy and a pair of receivers R1, R2 for receiving acoustic energy and defining between them a longitudinal span s1. The tool 10 can be used in an open borehole dened by surrounding earth formation 18 or can be used in a cased well bore.
It is noteworthy at this point that the present invention is equally compatible Awith multireceiver and transmitter systems, such as the four-receiver two-transmitter system disclosed in my copending application Ser. No. 356,186, filed Mar. 31, 1964, now Patent No. 3,304,537, and assigned to the assignee of this invention.
Rather than complicate the present disclosure with details of a four-receiver two-transmitter system as disclosed in the above application or the details of a two-receiver two-transmitter system as shown in Patent No. 3,257,639, an abbreviated system will now be described for obtaining successive time measurements. However, it should be appreciated that the present invention is concerned with the processing of successive digitalized signals from a borehole instrument to obtain a selected output result.
In one aspect of the present invention, the selected output result is a combination of such successive digitalized signals and representative of a measurement over a greater section of the well bore than the distance between the measurement means used to derive the successive digitalized signals.
As shown in FIGURE 6, a surface located programming circuit 10051 provides successive timing signals via a conductor path 101 in electrical cable 12 to a delay circuit 102 in the tool and to a switch control means 103. The switch control 103 operates a switch 104 to alternately connect one of the two receivers R1 or R2 to an output channel 105. After switching between receivers has occurred, the appropriately chosen delay of circuit 102 actuates a transmitter firing circuit 10651 which, in turn, pulses the transmitter and, at the same time, a fire pulse signal is sent to the output channel 105 for transmission to the surface as an indication of the time of transmitter tiring. The generated acoustical energy is successively intercepted by receivers R1 and R2 and a receiver signal from one receiver is passed via the switch 104 to the output channel 105 for transmission to the surface as an indication of the energy received by the receiver. On successive timing signals, the receivers alternate so that successive signals sent up the cable 12 represent the time of firing of the transmitter, the R1 signal, the time of transmitter firing and the R2 signal in a repetitive sequence.
From the foregoing, it will be appreciated that if the time interval between the transmitter firing and the R1 signal is subtracted from the time interval between the next transmitter firing and the R2 signal that the difference will be the time required for acoustic energy to pass along the formations between receivers. This time measurement can be related to porosity of the formations in a well known manner. It should be appreciated that the rate of firing for TR1 and TR2 is suiciently fast that the tool moves negligibly between two successive iirings. Thus, the measurements are obtained over substantially the same section in the well conduit.
The transmitter T signals and receiver R signals are transmitted over a conductor path 20 to a surface located counter control unit 22. in brief, the counter control unit 22 supplies pulse signals to a bidirectional binary counter 24 in response to the first electrical signal (from the transmitter) to arrive over the conductor 20. The counter 24 then begins to count at a uniform rate and continues to do so until the counter control unit 22 stops the supply of pulse sigmals to the counter 24, the control unit 22 stopping in response to an electrical signal on the conductor 20 from the receiver R2. The count accumulated by the counter 24 during the counting interval is therefore a digital binary number representing the travel time of acoustic energy between the transmitter and receiver R2.
The circuit also provides via a conductor path 106 an add-subtract direction to the counter 24. Thus, on the next timing pulse, the counter is set to subtract. The subsequent transmitter T and receiver R1 signal start and stop the supply of pulse signals to the counter 24 and the counts occurring between this time interval are subtracted from the previous TR1 count. After the end of a TR1 and TR2 cycle, the circuit 100 produces a transfer instruction over the conductor 106]; to condition an intermediate transfer memory unit 26 to accept the digital count in the counter 24 and to discard the previously held count. The net count is then temporarily stored on an intermediate transfer memory unit 26 and the counter is cleared immediately thereafter by a reset 107 (operated by the signal in the conductor 106b) to develop the next net count as described previously.
In the multitransmitter and receiver systems such as the 2T-4R system previously mentioned, several individual acoustic measurements (between each transmitter-receiver pair) are combined to yield a single acoustic measurement indicative of the desired properties of the surrounding borehole media and free from many of the errors commonly associated with acoustic travel-time logging. In such systems, the individual acoustic measurements are developed sequentially so that a total of four individual measurements are processed by the counter to yield the final electrical indication of the desired measurement. For example, as each travel time measurement is received, the count on the counter changes by a corresponding digital quantity. In the 2T-4R system two of such digital quantities are added, while the remaining two are subtracted in the counter, which is preferably of the bidirectional type in these applications.
If, in the present case, the tool 10 is equipped with the 2T-4R transducer arrangement, the counter 24 may be controlled to count up or down (add or subtract) depending on the particular acoustic measurement being received, For this purpose, the system of FIGURE l may be provided with a selector-programmer unit (not shown) of the type disclosed in the above copendiug application Ser. No. 356,186 to develop the required control of the counter and associated functions. Additionally, means similar to those disclosed in that application should be provided for resetting the counter and transferring its output to the transfer memory 26 only after all four of the individual acoustic measurements have been made and processed, thus ensuring that the digital signal passed to the transfer gate 46 represents the final desired measurement, i.e., the measurement derived from the four individual converted and combined acoustic indications.
A description of a suitable counter control unit 22 may be found in the foregoing copending application. For convenience, however, this unit has been shown in detail in FIGURE 2 and a brief description of its operation may be helpful at this time.
Referring to FIGURE 2, the transmitter and receiver signals on the conductor 20 are individually amplified in the amplifier 28 and simultaneously applied to a pair of detector gates 30 and 31. A timing pulse from circuit 100 (FIGURE 6) is supplied after a suitable delay (but prior to the occurrence of a transmitter fire pulse) to the detector gate 30 over the conductor 32 to energize the gate 30 shortly before the arrival of an electrical signal representing the transmitter firing. At this time,
the detector gate 31 is in the closed or blocking condition.
Upon arrival of -the amplified electrical signal from the output circuit 105, the signal is passed through the detector gate 30 to the pulse generator 34 which develops an output pulse indicating the arrival of an electrical signal at the surface. This pulse, in turn, activates a flipflop 36, the output of which opens the gate 38 to allow constant frequency pulses from a clock pulse generator 39 to pass to the binary counter 24, In addition, the pulse from the pulse generator 34 energizes a delay unit 40 which, after a short period of time (prior to the earliest expected receiver signal), opens the detector gate 31. At the same time, this pulse is used to deactivate gate 30, which returns to the off condition.
Upon arrival at the surface, the signal from the receiver R2 passes through the now open detector gate 31 to the pulse generator 42 which generates at its output a pulse to return the Hip-flop 36 to its original state, thereby checking the flow of clock pulses to the counter 24. Simultaneously, this output pulse is employed to again close the detector gate 31 and place the unit 22 in condition to receive the next successive electrical signal from the transmitter. At this point, the count accumulated by the binary counter 24 is a digital signal representing the travel time of the transmitted acoustic wave between the transmitter and receiver R2. The next succeeding transmitter and receiver (R1) signals operate the gate 38 in a similar manner. In 2Tw4R transducer arrangements, two additional digital signals will be developed by the counter before the final count is passed to the memory 26, with each additional digital quantity being added or subtracted to the first in accordance with a predetermined sequence provided by the selector-programmer unit briefly mentioned earlier.
In accordance with the invention, the travel time of the acoustic energy over a longitudinal span s2 greater than the span s1 defined between the receivers R1, R2 can be determined. As previously mentioned, this could be done by removing the tool from the borehole 14 and exchanging it for another having a different receiver spacing or, alternatively, to employ a tool having several receivers spaced apart at a distance equal to the desired span and then selectively coupling the receivers corresponding to the span desired to the cable. However, this is not always possible or desirable. In the FIGURE 1 system, At measurements stored on the transfer memory 26 are processed, in a manner now to be described, to develop an output signal representing a travel time measurement equivalent to that which would be obtained using a receiver spacing other than the spacing s1.
For purpose of explanation, it will be assumed that the receiver span is one foot and that the formations 18 are logged at a rate of 3600 ft. per hour so that the tool 10 moves through the borehole 14 at a rate' of 1 foot per second. It will also be assumed that the transmitter T is rapidly pulsed twice at each six-inch interval along the borehole to send acoustic energy through the formations 18 and make appropriate measurements, although in the usual case this interval will be much smaller, with only certain of the signals stored in the memory 26 being additionally processed. Beginning with the tool 10 in the lowermost position shown by the phantom lines, the transmitter T is excited twice and a first measurement is obtained representing the travel time of the acoustic waves over the longitudinal formation zone s1" dened between the receivers R1, R2. After the tool 10 has traveled uphole a distance of six inches, the transmitter T is again pulsed twice and a second At measurement 1s obtained representing the acoustic travel time over the longitudinal formation zone s1.
After the next six-inch incremental movement of the tool, the receivers R1 and R2 are in the positions shown so that a third At measurement corresponding to the next one-foot formation zone s1 is developed, and so on. Successive electrical indications of the travel time of the acoustic energy through the formations are therefore produced for every 1/2 foot movement of the logging tool through the bore. In the case described, the logging tool 10 has moved through a longitudinal distance of 1 foot and has logged the formations 18 between the lower limit of the receiver R2 and the upper limit of the receiver R1, or a distance or span of s2 which is 2 feet. By combining the indications obtained from successive logging measurements over the spans s1 and s1', the average travel time Al over the span s2 of `acoustic energy per receiver span s1 can be derived.
Continuing with the description, a conventional intervalometer 44 supplies, over the conductor 45, pulses at a rate synchronized with the movement of the tool 10 through the borehole 14 to the control terminal of a transfer gate 46 receiving the digital output from the transfer memory 26. In the' above example, the intervalometer 44 will supply a pulse at 1/2 foot intervals of movement through the borehole. In this manner, the contents of the transfer memory 26 are gated under control of the intervalometer pulses through the transfer gate 46 after every 1/2 foot movement of the tool 10, and it is not ordinarily necessary that the intervalometer pulses be synchronized or timed with the transfer signal to the memory 26, owing to the small probability of coincidence of the intervalometer and memory transfer signals and the signal response of the transfer circuits. The transferred digital signal is applied to a register 48 containing sevcral stages 50 to provide depth correction delay of the ultimate output signals, as will be explained subsequently, and the consecutive stages `51, 52, 53, 54 and 55. It should be noted that the binary digital quantity or word transferred from the memory 26 may contain several bits, each of which is transferred in parallel to a corresponding element of the first stage of the register 48. Typically, a IO-bit word is used so that each register stage is capable of storing ten informational bits. For simplicity, however, only one element of each register stage has been illustrated.
Each intervalometer pulse on the conductor 4S is also simultaneously applied to each of the' register stages 50 and 51-55 to transfer the digital Word stored in each stage to the next consecutive stage, the digital information in the last stage 55 being discarded as it receives the information from the stage 54. Thus, when the transmitter T is pulsed twice to transmit acoustic energy over the formation zone s1, a digital signal corresponding to At through this zone is developed and stored in the memory 26, and the intervalometer signals the transfer of the preceding digital quantity from the memory 26 to the first stage of register 48.
After development of the next electrical indication corresponding to the travel time of acoustic energy through the distance s1', another signal from the intervalometer 44 is applied over conductor 45 both to the transfer gate 46 and stages 50 and 50-55 of the register 48, thus entering the signal corresponding to the span s1' in the first stages 50 and shifting the s1" information contained in the first stage to a consecutive stage. Simultaneously, the digital information stored in the following register stages is transferred to their respective consecutive stages. As noted above, the digital word in the last stage 55 is dropped, with the' accompanying shifting of the contents of each stage to one stage to the right, to make room for the incoming digital word at stage 51. As will be recognized, therefore, the stages 50 (as well as stages 51, 55) function as a shift register.
The number of depth correction delay stages 50 will be related to the amount of distance `delay desired at the pulse rate (pulses/foot) of the intervalometer. The stages 50 of the register 48 transfer each digital word consecutively from one stage to the next upon each occurrence of an intervalometer pulse. Thus, when a digital word from the memory 26 finally reaches the stage 51, it will have been delayed in time by an amount equal to the time required for thel tool to move a given distance through the borehole. In FIGURE l, the stages `51-55 are at the end of the register chain of stages, and thus the At information to be extracted from these stages may be read out simultaneously with different information gained from other instruments (not shown) carried by the tool but physically located below the so-called center of measurement of the sonic transducers T, R1, R2. All such information therefore, is correlated to a single point or measurement zone in the borehole.
For purpose of explanation, We may assume that the lowermost instrument in the tool is located ten feet below the center of measurement of the sonic transducer and that it is wished to read out the' At information simultaneously with information derived from this instrument, so that all information relates to the same formation zone even though the tool continues to move through the borehole. If a pulse from the intervalometer is developed for every 1/2 foot of tool movement, then 2 l0=20 register stages are needed in the group of stages 50 to provide the necessary vdelay of the At signals. It should be remarked that the consecutive stages 51-55 may be located anywhere within the register stage chain, depending on the delay required.
After movement of the tool over a predetermined distance, during which time the At digital signal corresponding to the s1" zone consecutively advances through the register 50, the signal is transferred from the last of the stages 50 into the stage 51. Upon arrival of the next digital Word, corresponding to the zone s1', the s1 signal is transferred to stage 52, with the s1 information now stored in stage 51.
The acoustic arrival time signal through the longitudinal formation zone s1 is similarly applied to the first stage 51 of the register 48, whereupon the information corresponding to the s1' and s1 zones is transferred to the respective stages 52 and 53. As will be apparent shortly, two further digital words will be stored in the register 48 as the tool 10 moves through an additional distance of one foot, each Word corresponding to travel time over successive one-foot zones six inches apart. At this point, stage 55 contains s1" information stage 54 s1 information, stage 53 s1 information, and stages 51 and 52 the digital words corresponding to the preceding two acoustic measurements.
'It is apparent that the stages 51-55 in the register 48 contain digital signals representing the acoustic travel time through successive longitudinal 1-foot formation distances defined between the receivers R1 and R2, each of the distances being displaced from the next by six inches.
As already lnoted, it has been assumed that the acoustic transmitter is excited at six-inch intervals of sonde movement. It is clear, however, that the repetition rate of transmitter excitation may be much higher, for example 20 or 10 per second (every 1-2 inches of tool movement). In such case, only certain of the electrical indications held by the memory unit 26 will be processed through the register 48, as determined by the intervalometer pulses or conductor 4S. From the foregoing description, it will be realized that the register 4S need not take any particular form, as long as the described storing functions can be performed. Accordingly, any of a number of known types of storage circuits may be employed, such as the solid state, vacuum tube, and ferrite memory plane or other magnetic types.
As explained above, the electrical indications, or digital signals corresponding to the logged longitudinal zones s1, s1 and s1, may be combined to derive an output signal representing the effective average travel time of acoustic energy per receiver span over a formation zone having a different dimension, e.g., s2. For a tool in which the receiver span or spacing is one foot, the output signal will represent the average acoustic travel At per foot over a zone determined by the number of successive At indications that are combined.
In the FIGURE 1 system, the effective span is chosen by periodically sampling the output of stage 51 for an effective one-foot span, stages 51 and 53 for -a two-foot span, and stages 51, 53 and 55 for an effective three-foot span. From the preceding it Will be realized that at the time stage 55 of the register 48 contains digital information of the travel time through one formation zone, stage 53 holds information of acoustic travel time through a formation zone one-foot uphole of the first zone, and stage 51 holds At information for the formation zone two feet uphole from the first zone. The o-utputs of these stages are routed to respective AND gates 58, 59 and 60 each of which, like the register stages, includes a number of elements sufficient to accept the number of information bits of the words stored in the register. A single three-input terminal -OR gate 61 connected to the outputs of the AND gates receives, upon activation of the respective AND gate, the digital signal stored in one of the register stages 51, 53 or 55.
A gate control unit 62 supplies sampling pulses over the conductors 64, `65 and 66 to control the :gating action of the associated AND gates 58, 59 and 60' only one at a time in a sequence depending on the effective span desired. For example, if a travel time At sec./ft. is desired for an effective receiver spacing of two feet, the -gates 58 and 59 are energized by the sampling pulses to alternately pass the contents of stages 51 and 53 to the OR gate 61. It is understood that the OR gate 61 is capable of accepting the same number of bits as the gates 58-60. Only one element of the gate 61, however, is shown for simplicity. If an effective receiver span of three feet is wanted, the gates 58, 59 and '60 are activated in sequence so that the OR gate 61 receives first the output of the stage 51, then the output stage 53, and finally the output of stage 55. For At measurements over a l foot span, the AND gate 58 only is continuously enabled.
The digital signals gated through the OR gate 61 are converted into analog signals in the binary digital/ analog converter 68 which yields pulses having durations equal to the lengths of the sampling pulses and amplitudes proportional to the sampled digital quantities. The analog pulses are then filtered in the galvanometer filter 70 and applied to a recording galvanometer 72.
In the ordinary case where the average acoustic travel time per receiver span is desired, each of the gates 58, 59 and 60 will be energized for equal periods of time.
It is desirable that the sampling rate be greater than the rate at which successive electrical indications from the transfer memory 26 are transferred through the individual stages of the S-stage register 48. For a register shifting rate of, say, 2 shifts/sec., the sampling rate might be 20-300 samples/ sec. The pulse output of the binary digital/analog converter 68 will then also have a frequency of about 20300 pulses/sec. When these analog pulses are applied to the galvanometer filter 70, they are effectively averaged to produce a continuous analog signal for recording by the recording galvanometer 72. By thus making the combined response of the galvanometer filter 70 and the recording galvanometer 72 substantially less than the rate at which pulses appear at the output of the converter 68, the sampled quantities from the stages 51, 53 and 55 representing acoustic travel times can be conveniently averaged.
FIGURE 3 depicts in detail a representative type of gate control unit 62 suitable for controlling the sampling action of the AND gates 58, 59 and 60. For convenience, it is assumed that the pulses on the conductors 64, 65 and 66 are of all equal duration and that the operation of the unit 62 is initiated by a starting pulse 75 (FIGURE 4101)) on the conductor 76 from a suitable pulse generating source (not shown). Upon receiving the starting pulse 75, the monostable multivibrator 78 generates a square samplin-g pulse 79 (FIGURE 4(b)) which passes to the conductor 64. The trailing edge of this pulse is differentiated in the unit v80` to produce the sharp pulse l83 (FIGURE 4(c)) for application through a selector switch 82 when in position 2 or 3 to a second monostable multivibrator 84. The pulse I83 triggers the multivibrator 184- to generate a sampling pulse `85 (-FIGURE 4(d)) on the conductor 65. A second differentiator 87 shapes the trailing edge of the pulse 85 to produce the pulse 8'8- (FIGURE 4(e)). The pulse 8'8, in turn, is applied through a selector switch 92 in the 3 position to a third monostable multivibrator 90. Upon receiving the pulse l88, the multivibrator 90 generates a third sampling pulse 94 for application to the conductor 66.
As indicated by the dashed line connection, the movable contacts of the switches 82 and 92 are mechanically coupled together and to the movable contacts of ganged selector switches 96 and 96a. When the output of the first stage 51 (FGURE 1) of the register 48 is to be continuously sampled so that the recording galvanometer 72 records an output signal representing acoustic arrival times over a 1 foot receiver span, the switches 82, 92, and 96a are thrown to position "1. In this case, a D.C. signal from a D.C. source 100:1 is applied directly to the lead 64, thereby continuously enabling the gate 58. At the same time, the multivibrator chain of the gate control unit 62 is opened by the switch 82, and no pulses appear on conductors 65 and 66.
For At measurements corresponding to an effective 2foot receiver span, the switches 82, 92, 96 and 96a are moved to position "2. The multivibrator 78 is then energized by the pulses 88 at the output of the differentiator 87, thus causing the multivibrators 78 and 84 to be triggered alternately and producing alternately occurring sampling pulses on the respective conductors 64 and 65. With the switches in the 3 position, as shown, the operation of the unit is that described in connection with FIGURE 4,y wherein each output conductor 64, 65 receives every third sampling pulse to energize the AND gates 58, 59 and 60 in sequence.
From the foregoing, it is apparent that the invention provides an improved system for controllably changing the effective receiver span of a fixed-span logging tool. This is, moreover, accomplished through the use of computing equipment which is substantially less complex than the equipment that would be required to implement conventional digital computing techniques.
Although the invention has been described with reference to the specific embodiment thereof, it is understood that many modifications and variations, both in form and detail, may be made within the skill of the art. For example, it is apparent that more register stages may be employed to obtain better logging resolution and a smoother curve on the recording galvanometer 72. Thus, two stages rather than one stage may be interposed between the register stages whose outputs are sampled. In this case, digital signals are transferred between consecutive stages after every four inches of sonde movement. As a further example, analog computing techniques may be substituted for the digital elements to perform analogous functions.
All such modifications and variations, therefore, are intended to be included within the scope and spirit of the invention as defined in the appended claims.
