Abstract

The complex tectonic structure of the Okhotsk Sea shelf and the high level of geodynamic activity necessitate the use of geodynamic simulations to forecast the secondary filtration-capacity properties of reservoirs. The 3D geomechanical models were built and the forecasting of the fractured porosity and permeability was conducted for the Kirinskaya, Ayashskaya, and East-Odoptinskaya license areas. The simulation revealed filtration channels, where both vertical and horizontal migration of hydrocarbons occur. It was found that the secondary permeability of the upper and the lower stratigraphic horizons of the studied area significantly differ. The Okobykai clayey member is the boundary surface and serves as the regional cap. All calculations were performed on the 3D-grid geological model, which allows us to use the data for hydrodynamic simulation.
