TEHRAN (FNA)- The Iranian oil ministry said it is about to start a plan of simultaneous injection of water and gas into Doroud oilfield to boost the volume of oil recovery in the field.
Managing-Director of the National Iranian Offshore Oil Company (NIOOC) Mahmoud Zirakchianzadeh said that simultaneous water and gas injection into the Doroud oil field, located off the Persian Gulf island of Kharg in Southern Iran, would enhance its recovery rate from 23 to 33 percent.
Water injection is a method of improved oil recovery (IOR) applied to offshore reservoirs, said Zirakchianzadeh on Friday.
Currently, 400,000 barrels per day (bpd) of water are injected into the NIOOC-administered fields aimed at increasing oil output. The figure will reach 500,000 to 530,000 bpd by the end of the current Iranian calendar year (to end March 21, 2014), the official added.
The NIOOC as one of the largest oil companies operating in offshore sector produces a great part of the country's oil and gas in 1,200 kilometers of the Persian Gulf waters. The company comprises six operation districts including Bahregan, Lavan, Siri, Kharg, Kish and Qeshm.
