Abstract

The article is devoted to the study into conditions of formation of secondary organic porosity—void spaces of organic origin as a result of transformation of organic matter into hydrocarbons in low-permeability shale strata. The experience of studying and developing the known shale formations in the world proves the fact that such strata are hybrid phenomena, i.e., they are both producing strata and reservoir-type strata. Based on the results of the programmed pyrolysis by the Rock-Eval-6 method, the organic (kerogen) porosity is estimated. The study into geochemical characteristics of organic matter in the samples from wells drilled at various test sites makes it possible to analyze causes of rock matrix retention capability.

The reported study was funded by RFBR, project number 20-35-70062.
