Exploration and Mining
The task of developing carbonate reservoirs has now become extremely important. Low technological indicators of development are explained, as a rule, by an inefficient well placement system, complex geological structure, high oil viscosity, water breakthrough and the occurrence of technological complications in the process of field development. The aim of the work is to refine the geological and reservoir simulation model of a complexly built carbonate reservoir, in terms of areal coverage of wells by hydraulic fracturing. The determination of the directions of the hydraulic fracture along the section (up or down), along the area of work and involvement in the development of non-target objects were obtained. The objectives of the study include the analysis of the direction of strain-stress distribution in 2 hydrocarbon deposits of the selected area and the study of the geochemical properties of the reservoir fluid over the entire area of work. First, a geomechanical model was built, which is a numerical representation of the state of stress and rock mechanical properties. Then, geochemical studies of samples were carried out over the area of work from each layer. As a result, for a well with hydraulic fracturing, the involvement in the development of reserves of the target and non-target fracture creation object was quantified. Finally, a geological-hydrogeochemical adaptation of the model was performed, which showed the best result with additional methods for studying the composition of the fluid and geomechanical modeling.
