Today, it has become pretty obvious that the rocks that were conventionally believed to be source rocks are, in many cases, oil bearing rocks. This oil bearing potential can be attributed to both filtration of the hydrocarbon fluids in the reservoir and artificial generation of liquid and gaseous hydrocarbons by heating the solid organic matter underground. The suggested differentiated approach to estimation of the resource base allows identifying and assessing oil bearing potentials for various reservoir stimulation techniques: drawdown (due to natural reservoir properties of the rock), creation of artificial permeability, and generation of hydrocarbons by in-situ pyrolysis of the organic matter.
