Application of new technological solutions for improving development efficiency of the Korchagin field

Abstract

In this thesis oil and gas condensate Yu. Korchagin field is considered. It is located in the northern part of the Caspian Sea. Thus, production at this field is complicated by both marine production conditions and Arctic conditions in the winter season. One of the main difficulties associated with field development is the presence of a massive overlying gas cap and underlying water, where the oil rim has a thickness of only 20 m. In the master's thesis, an analysis of the reasons for the gas factor growth during the operation of horizontal wells was made, as well as its influence on the development parameters of the Yu. Korchagin field. The theoretical part of the work covers a description of the climatic, geological and geographical conditions of the field, as well as a description of the technical and technological components of the field development project. In the calculation part, a description of the design solution to limit gas and water inflow to the well is presented, which consists in the use of additional production wells in the gas- and water-saturated parts. Also, the technological and economic efficiency of the proposed solution was evaluated. The calculations were carried out using a hydrodynamic simulator.
