Non-stationary water injection as a way of waterflood system performing

Authors: O.E. Tarakanova, M.M. Galiullin, N.V. Dubovetskaya (TNNC LLC, RF, Tyumen)

Key words: non-stationary water flooding, cyclic water flooding, direction change of filtration flows, hydrodynamic EOR methods, optimization formation pressure maintenance system.

Currently water flooding implementation represents the major condition for successful depletion of oil fields’ pay zones. However, in case of a high reservoir heterogeneity water flooding performance reduces due to irregular distribution of injected water. One of the accessible methods of displacement front alignment is conversion of the implemented flood pattern to a non-stationary operation. This work reviews the possibility to implement non-stationary water flooding in Sorochinskneft fields, it also determines the top priority development targets for the method implementation, and a program of non-stationary water flooding is prepared for a pilot area along with its performance evaluation.
