The article presents the practical results of the building of a four-dimensional Mechanical Earth Model of the field on the Sakhalin shelf. An analysis of the stress regimes, both regional and local, was carried out. The model was built on an extensive data set, including core and wellbore studies, special logging and leak test results, and allowed to evaluate the initial and current stress-strain behavior, reservoir compaction, stress re-orientation. The article also details the methodology and details of building a four-dimensional Mechanical Earth Model which can be useful for specialists in this area. Important practical problems were solved on the model - the technological efficiency of MSHF was proved and the efficiency of expensive compaction drilling was increased in offshore conditions. In addition, the risks associated with the first MSHF planning in the region were evaluated, such as the fracturing of the hydraulic fracturing crack into overlying aquifers, the development of crack in the horizontal direction, as well as uncertainties caused by a limited set of data.
