Recently, in connection with earthquake prediction in many geodynamically active zones, special attention is paid to the study of changes in geophysical fields in time and space. According to the results of conducted regime observations, it was justified that the intensity of changes in geophysical fields in seismically active zones in the period of processes activation appears still more. The study of properties of abnormally high formation pressures and electrical resistance of homogenous rocks by three tectonic blocks in many wells of Kursangy field of Low Kura depression has been carried out. As a result of it, the revaluation of changes character in oil saturation has been conducted and the graphics of changes in abnormal formation pressures in the same selected profile made as well. It was defined that the changes of indexes in formation pressures within the profile in each separated block are noted and the reason for such stability is connected with the time changes in seismic-geodynamic conditions in the square.
