The combined reservoir rock and fluid data sets are used by operating companies to  determine the production potential of the reservoir and the perforation, stimulation,  and production programs that will be most effective. Tight-oil reservoirs differ greatly from one another in their petrophysical compositions  and hydrocarbon content. For example, the Bakken formation is very different from  the Eagle Ford shale. Therefore, customized strategies based on the core analysis  and reservoir fluids data are critical to optimizing daily hydrocarbon flow and  maximizing the ultimate total recovery of crude oil and other hydrocarbons from  each distinct reservoir. Based on reservoir rock and fluids data  sets from thousands of feet of core, Core  Lab has developed numerous technolo- gies, products, and services to enhance  production from tight-oil reservoirs. They  are proving very effective in Bakken,  Eagle Ford, and Permian Basin reservoirs.  This is especially the case for multi-staged,  multi-well simultaneous fracture programs  in which multiple wells in close proximity  are fractured together in multiple stages.  Here Kodiak ™  perforating charges and  gun systems are used along with  ZeroWash ® , SpectraStim ™ , SpectraScan ® ,  and SpectraChem ®  fracture diagnostic  services. Core’s new FlowProfiler ™  tech- nology is then used to determine which  fracture stages are flowing crude oil and  to measure flow volumes. Kodiak perforating charges are one of Core’s newest technologies being  applied to maximize the flow of crude  oil from wells being drilled in tight-oil  reservoirs. Unlike conventional perforating  charges that have limited depth of  formation penetration and leave signifi- cant debris in the perforation tunnel,  Kodiak charges continue to meet Core’s  highest engineering design expectations  by achieving exceptional formation  penetration and producing minimal perforating debris (Figures 5 and 6).  Figures 5 and 6. While conventional perforating charges have a limited  depth of formation penetration and leave significant debris in the perforation  tunnel, Kodiak charges achieve exceptional formation penetration and  produce minimal perforating debris.
