Russia’s Lukoil has presided over a major discovery at Iraq’s exploration Block 10, raising new expectations of ultimately producing over 300,000 barrels per day (bpd) from the Eridu field. Preliminary estimates suggest Eridu could hold between 7 and 10 billion barrels of reserves, which would make it one of the top seven largest fields in the country, according to two senior officials at the Dhi Qar Oil Company (DQOC), which is Iraq’s state partner in the development of Block 10.
