Improvement of oil and gas field development technology

During the period of depletion of the main oil reserves in fields entering the last stage of development due to the priority development of highly productive highly permeable reservoirs, an increasing proportion of residual reserves become difficult to recover.Therefore, it becomes relevant to use effective methods of increasing oil recovery in existing fields, most of the original volume of geological reserves remains in the deposits. One of these methods is unsteady waterflooding, which has proven its effectiveness in a number of fields.
