ASSESSMENT OF RELATIVE VALUES OF RESERVOIR PRESSURE OF FLUIDS IN COLLECTORS: RESULTS OF CONDUCTED EXPERIMENTS AND PROSPECTS OF PRACTICAL APPLICATION

Levashov S.P., Yakymchuk N.A., Korchagin I.N.

The results to experimental approbation of the methods of estimation of reservoir pressure of fluids within the framework of technology of the remote sensing (RS) data processing and interpretation for the “direct” prospecting and exploration the hydrocarbon (HC) deposits are given. Technology allows to find and map operatively the anomalous zones of “oil deposit” and (or) “gas deposit” type, which are conditioned by the HC deposits of different sizes and under different (including zero) values of reservoir pressure of fluids. Zones with raised reservoir pressure within mapped anomalies fix the areas, within which the probability of receiving of payable inflow of HC are substantially above. The practical application of method allows to narrow essentially the areas of conducting the detailed exploration investigation of priority character and the exploratory boreholes location. Technology of the RS data processing and interpretation is actively used in complex with land-based geoelectric methods of forming short-pulsed electromagnetic field (FSPEF) and vertical electric-resonance sounding (VERS) that allows to raise essentially theirs efficiency and informational value. Essential effect can be received from this technology integration with other geophysical methods and, in the first place, with high-resolution 3D-seismic prospecting method.
