LUANDA, May 1 (Reuters) - U.S. firm Cobalt International Energy has discovered significant quantities of oil offshore Angola, state oil firm Sonangol said, calling the find the biggest so far in the promising pre-salt layer in the Kwanza Basin.
Oil drillers hope discoveries under a deep submerged salt crust off Angola known as pre-salt may match the prolific finds beneath similar deposits off Brazil on the other side of the Atlantic in recent years.
Analysts say Angola, Africa's No. 2 oil producer, could double its oil reserves, which are currently estimated at just under 13 billion barrels, if pre-salt drilling proves successful.
Drilling at Cobalt's Orca-1 well in Block 20/11 reached a depth of 3,872 metres and has successfully produced over 3,700 barrels of oil and 16.3 million cubic metres of gas per day, Sonangol said in a statement on Thursday.
