The Rumaila Operating Organization (ROO), composed of BP, PetroChina and the South Oil Company of Iraq, announced that the Rumaila oilfield has produced 3b barrels of oil since the joint venture began operating in January 2010, Rigzone reported.

Accordingly, Iraq has received an estimated $200b in revenue from Rumaila during the years of operations. Currently, the field’s oil production is at its highest rate at more than 1.45mb/d, up from 1mb/d. The production increase was achieved despite challenging geological conditions and aging infrastructure and equipment, informed E&P Magazine.

Under ROO’s management, the number of producing wells at Rumaila has risen by about 50%, with more than 240 new wells drilled and an ongoing well work-over program implemented to counter the mature field’s natural rate of decline. Real-time well logs, advanced core sample analysis, 3-D subsurface maps and other cutting-edge technologies have improved well performance, drilling accuracy and efficiency.

Iraq’s Minister of Oil, Jabar Ali al-Luaibi, said: “Rumaila is a crucial oil field and we look to our international partners and Iraqi colleagues to continue to increase production from the field in the years to come.”
