خلاصه مقاله:
In the common methods of water and gas injection, high and unsuitable mobility ratio within the injected fluid and the oil in the reservoir, leads toviscose fingering and reduction of sweep efficiency. To improve sweepefficiency alternating slugs of water and gas (WAG injection) designed. Injection of water slugs followed by gas, leads to triple region, increase the contact level of injected fluid and reservoir, stable the movement front,and finally increase the recovery.In this work, scenarios of WAG and Simultaneous WAG (SWAG) are compared to specify the appropriate injection method. Then ultimate oilrecovery, residual oil saturation, daily and total oil production are compared in these scenarios. Also these scenarios in two five spotinjection patterns were compared. Results indicated that, SWAG injection has the higher oil production and lowest residual oil saturation. So adding the number of wells without increasing in oil rate could raise the recovery.
