FIELD: oil production industry. SUBSTANCE: according to method, determined after monthly time intervals are current and accumulated amounts of recovered oil prior to application of procedures for increasing oil recovery from beds. After that, separated are stages of bed development and determined is basic period of development and also anticipated and actual accumulated amounts of oil during period after application of procedures for increasing oil recovery from beds. According to change in actual collected amounts of oil, determined is efficiency of procedures for increasing oil recovery from beds during period after application of procedures in comparison with forecasted accumulated amounts of oil during same period. Assumed as basic period is time interval corresponding to last separated stage in development of bed. Application of method allows for improving accuracy in determining technological efficiency of procedures for increasing oil recovery from beds. EFFECT: higher efficiency. 5 dwg
