Due to the expansion of drilling depth in oil and gas wells with the use of new technologies during drilling and production of reservoirs, several problems have increased costs and reduced production efficiency. One of the problems we face in most wells today is water shut off. In this article, according to the studies conducted in this regard, Water Shut off System cases such as Water production resources, Reasons for water production, Water-Control Solutions, Ways to identify the location of unwanted water supply in wells Production, Types of Solutions to deal with it are addressed.
