Rumaila oilfield achieves three-billion-barrel production landmark

24th January 2017

The Rumaila Operating Organisation (ROO), composed of BP, PetroChina and the South Oil Company of Iraq, have announced that the Rumaila oilfield has produced three billion barrels of oil since the joint venture began operating in January 2010.

During the past six years, the oil produced from Rumaila has provided the Iraqi state with an estimated USD200 billion dollars in revenue.

Oil production at Rumaila is now at its highest rate in 27 years, producing over 1.45 million barrels per day, up from 1 million in 2009.

The production increase was achieved despite challenging geological conditions and ageing infrastructure and equipment within the 40-year-old field. Addressing these issues has seen the ROO partnership develop a performance-led culture, empowering the local Iraqi workforce to deploy new and more advanced technologies.

Under ROO’s management, the number of producing wells at Rumaila has risen by about 50 per cent, with more than 240 new wells drilled and an ongoing well workover programme implemented to counter the natural rate of decline of the mature field. Cutting edge technologies such as real-time well logs, advanced core sample analysis and 3D subsurface maps have improved well performance, drilling accuracy and efficiency.

In addition to the active drilling programme, one of the world’s largest water injection projects was completed to boost output in areas where reservoir pressure had fallen after half a century of production. Between March 2013 and October 2016, water injection increased from 60,000 to 900,000 barrels per day following renovation of the Qarmat Ali water treatment plant, five pumping stations and associated pipelines.

The refurbishment of other facilities also continues across the field. Rumaila’s degassing stations now treat around 1.8 million barrels per day of oil and produced water - volumes of fluids not seen since 1979. Investment in new oil, gas and water separation units, dehydrators and desalters, and produced water disposal units are proving vital in helping to sustain facilities, many of which date back to the 1970s.
