Abstract:

The article discusses oil recovery and ways to increase it, and also conducted a study and determination of oil recovery coefficients for geological and field data. The current state of work on oil recovery is shown. Some issues of the method for determining oil recovery coefficient are identified.

Keywords: oil recovery of the reservoir; oil recovery coefficient; current state of oil recovery; determination of oil recovery coefficient using geological field data; increase of oil recovery coefficient; degree of oil displacement by water; transition zone
