(Reuters) - Oil major BP Plc agreed on Monday to sell a 20% stake in Oman's Block 61 to Thailand's PTT Exploration and Production for $2.6 billion.
The London-listed firm said it would continue as an operator of the block, which contains a large tight-gas development in the Middle East, with a 40% interest.
"We are committed to BP's business in Oman – this agreement allows us to remain at the heart of this world-class development while also making important progress in our global divestment programme," said BP's Chief Executive Bernard Looney.
Block 61 already had two phases of development - Khazzan tight gas project, one of the largest upstream projects in the small Gulf state, and Ghazeer project which began production in October, BP said.
