The hydrofracturing method of in situ stress measurements has              evolved in the last fifteen years into an indispensable tool in                 geophysical research.  For example, a major objective of the first              deep scientific drilling in the U.S. at Cajon Pass, California, is              to measure the state of stress, primarily by hydrofracturing, in                the vicinity of the San Andreas fault.  Despite the general                     reliability of hydrofracturing, uncertainties in its                            interpretation still exist and cases where the method is only                   partially successful or totally unsuccessful are now surfacing.                 There are at least three major sources of difficulties in                       hydrofracturing data interpretation:  1) reading the correct                    pressures from field records, 2) using the correct model for                    calculating the in situ stresses and 3) evaluating the effect of                preexisting fractures on hydrofrac pressures and directions.  The               research will resolve some of these difficulties through                        laboratory testing and data analysis.  In addition, experimental                verification of suggested innovative improvements of the method                 has been carried out.  Such confirmation of one or more of these                alternate techniques would enable their use in either                           complementing replacing conventional hydrofracturing.
