Gas has been injected into Haftkel oilfield for the first time to enhance the field's recovery rate, managing director of Masjed Soleyman Oil & Gas Producing Company announced, IRNA reported.

 Masjed Soleyman Oil & Gas Producing Company accounts for six percent of the country's total oil production, Ebrahim Piramoun said, adding that the company can increase its output to 200 million barrels of oil. Gas injection into Haftkel oilfield was aimed at increasing the field's production. The field is located in the Southern part of Iran, with two carbonate reservoirs, Asmari reservoir on the top and Bangestan in the bottom.

Gas injection or miscible flooding, is presently the most-commonly used approach in enhanced oil recovery through introducing miscible gases into the reservoir. A miscible displacement process maintains reservoir pressure and improves oil displacement because the interfacial tension between oil and water is reduced.

Pointing to Masjed Soleyman oilfield, which is the oldest in the Middle East, the official said 17.5 percent of the field's reserves have been extracted so far. The field is estimated to contain 6.5 billion barrels of oil. So far 367 wells were drilled in the field, of which only 16 are currently operational.
