Abstract

The paper presents integral analysis of experimental data from laboratory studies on carbonate reservoir rocks of the Bashkir and Turney formations aimed at the measurement of rock permeability alteration under changing pore pressure and constant outer stresses. The dependencies obtained have been related to geomechanical treatment and initial reservoir properties of rock samples. Characteristic hysteretic effects of permeability alteration under cyclic changes of pore pressure on samples with different saturation have been revealed, and it was shown that cyclic geomechanical treatment can promote significant improvements of the flow characteristics of a carbonate reservoir. The published results were obtained in the research study on the topic “Justification of the mechanism of geomechanical treatment in carbonate reservoirs (Bashkir and Turney formations)” carried out by the Almetevsk State Oil Institute for PJSC Tatneft in 2019, and in the State Research Contract study of OGRI RAS on the topic AAAA-A19-119022090096-5.
