Prospects for the application of non-stationary waterflooding to increase the production of oil reserves

Abstract

At the final stages of the development of most of the deposits in Belarus, Russia and abroad, after the almost complete development of recoverable oil reserves, most of the initial volume of geological reserves remains in the deposits. At the moment, the volume of oil produced is only partially compensated by the increase in reserves due to the discovery of new deposits. More and more urgent is the application of effective methods of increasing oil recovery in existing fields. Methods, which in view of the current macroeconomic situation do not require significant capital investment. One of these methods is non-stationary waterflooding, which proved to be effective in a number of fields in various oil and gas provinces. In this article, the systematization and classification of existing technologies of hydrodynamical methods of influence has been made, the criteria for selecting objects have been singled out and recommendations on the technology of work have been made.
