State-owned Qatar Petroleum (QP) has farmed in to an ultra-deepwater block off Angola operated by Total where plans are in hand to spud a delayed wildcat that will set a record for the deepest water depth in which a well has ever been drilled.

QP said on Tuesday it has entered into a farm-in agreement with Angola's national oil company Sonangol and Total to acquire a 30% participating interest in 3600-square kilometre Block 48 in the Congo basin.

The block has a drill-ready opportunity that "is expected to be drilled as part of a 2020/2021 drilling programme", QP said.
