BP issued an assay of its Gulf of Suez Blend crude oil in late 2008. Start of production from Saqqara field earlier that year prompted the new assay.
The Gulf of Suez Petroleum Co. (GUPCO), a joint venture owned equally by BP and the Egyptian General Petroleum Co. (EGPC), is responsible for oil and gas production in the Gulf of Suez, the Western Desert, and the Nile Delta
GUPCO operations include Hapi field and Akhen field, which lie 50 km from the Mediterranean coast. Production capacity of the two wells of Akhen field (WA-1 and WA-2), says BP's web site, is 80 MMcfd and 5,200 b/d of condensates. GUPCO owns Idfu field in the Gulf of Suez with production capacity of 20,000-25,000 bo/d with expected reserves of 30 million bbl of oil.
Saqqara field, discovered by GUPCO in 2003, lies 12.5 km offshore in the central Gulf of Suez. First oil was achieved on May 15, 2008, and following commissioning the field ramped up to more than 30,000 b/d.
Saqqara is developed with a jacket and unmanned topsides, four wells, and a 13-km pipeline to new dedicated onshore separation and gas processing plant at Ras Shukeir, Gulf of Suez.
