In-situ conversion of kerogen from the production of synthetic oil is one of the possible ways to increase the profitability of the development of shale formation. To develop Bazhenov shale, such technologies as in-situ combustion and retorting, presupposing productive layers warming-up can be employed. Laboratory modeling of the thermo-catalytic effect on the kerogen samples of Bazhenov shale was carried out. Before separation kerogen from the rock sample, bitumoids were extracted by means of chloroform. Kerogen with pyrite was separated by the step-by-step dissolution of minerals with hydrochloric and hydrofluoric acids. To study the pyrite transformations the differential thermomagnetic analysis were used. According to the data of the X-ray structural analysis, it was determined that as a result of the thermal treatment, a part of monomineral pyrite transforms to the various magnetic forms. The degree of pyrite transformation directly depends upon the treatment conditions and the presence of oxygen. Phenomenon of transformation of pyrite to magnetic forms, which allows to control front of coverage of thermal impact of a deposit by geophysical methods from the surface.
