Features of development of US1 object at the oil field X

Abstract
The oil field X belongs to the category of large in terms of initial recoverable reserves, multi-layer and complex in geological structure. The US1 object accounts for 20,3 % of the initial recoverable reserves, while the selection from the initial recoverable reserves is only 11,4 %, this makes object the most promising from the point of planning further development of the field. The analysis presented in the article is aimed at identifying problems and features of the development.
During the analysis, we noted low reservoir properties of the object, high watercut of the produced products, the deterioration of the energy state of the deposits, which manifests itself in the form of a decrease in dynamic levels and a decrease in fluid flow rate. Drilling of wells, both production and injection, was carried out using hydraulic fracturing technology.
Given the fact that the deposits of the US1 object are closed, lithological shielded and are characterized by the absence of an oil-water zone, the watering of wells, according to the our opinion, is associated with pulling up water from the underlying water-saturated formation as a result of the propagation of cracks obtained during hydraulic fracturing. The reason for the deterioration of the energy state is the commissioning of injection wells using hydraulic fracturing and the withdrawal of water through hydraulic fracture in the underlying formation.
