IMPROVEMENT OF THE DEVELOPMENT SYSTEM OF TATARTSAN’S SMALL-SIZE RESERVOIRS AT LATE STAGES
A common approach to maintaining stable oil production rates relies on the increase of oil recovery from producing formations through optimized oil fields development strategy and wide use of enhanced oil recovery methods. Production enhancement operations include front displacement, as well as sidetracking water-producing wells to drain by-passed oil. Injection of polymer compositions as displacement agents finds wide application at the late stage of development. To increase production from low-permeability intervals, cross-linked polymer systems are recommended for injection.
