The study of methods for increasing production from hard-to-recover oil deposits is relevant all over the world, since the reserves of traditional reservoirs are decreasing, while the demand for hydrocarbons remains. The number of projects aimed at finding cost-effective ways to develop hard-to-recover oil reserves is growing. The continuous development of oil production technologies has a positive effect on the involvement of complex objects in development. In order to plan the successful development of hard-to-recover oil reserves, it is necessary to conduct preliminary studies, including predictive hydrodynamic calculations, which will allow determining the optimal development technology.

The authors of the article present the results of hydrodynamic calculations implemented to assess the degree of involvement of the low-permeable part of the section. The calculations used reservoir parameters and the results of laboratory experiments on core. Two fundamentally different approaches to modeling wells with hydraulic fracturing (HF) in the Upper Jurassic deposits are considered to analyze the effect of HF efficiency on the results of thermal impact. As a possible technology, the use of an induction heater with water injection is proposed, which will transfer heat into the formation, heating it and involving kerogen-containing rocks in development.
