The Abu Safah field (Arabic: حقل أبو سعفة) is a joint petroleum reservoir between the waters of Bahrain and Saudi Arabia.
Discovered in 1963 and beginning production in 1966, the field helped spur expansion of the Qatif Project from 150,000 barrels/day to its current 300,000 barrels/day capacity.
[2] Since 1996, the Kingdom has granted all production in the field to Bahrain, but Saudi Aramco markets it through the port of Ras Tanura and distributes the revenues equally between the two.
Before this, Bahrain would produce 37,000 barrels/day and import up to 217,000 barrels/day through an undersea pipeline between Saudi Arabia and a refinery on the Bahraini island of Sitra.
[3][4] The Abu Safah reached its full 300,000 barrels/day in 2004, after $1.2 billion was spent to raise the capacity to that level.
