The involvement of the nontraditional hydrocarbons reserves in the development becomes recently ever more actual. The strata of Bazhenovskaya suite are characterized by low permeability and porosity, a large quantity of organic matter consisting of the kerogen and the light oil is contained in the stratum rocks. As a result of the strata rocks thermal treatment their general voidage increases, and the undrainable zones are converted into drainable ones, forming in this case the additional inflow of oil. The kinetics of the oxidation of the kerogen-containing rocks is studied experimentally in VNIIneft OAO on the differential scanning calorimeter of high pressure HP DSC1 for the realization of the method of thermal gas treatment of Bazhenovskaya suite rocks. The obtained results show that in the low-temperature range of the oxidation Bazhenov suite rocks have the close values of the activation energies of oil and drainage rocks. This causes subsequently their joint involvement in the oxidation processes.
