Total has scrapped plans to buy assets that had belonged to Anadarko Petroleum in Ghana.
Tullow Oil has slashed spending in 2020 and set out major disposal plans in an attempt to weather the storm.

Kosmos Energy notched up $16 million in net income for the third quarter, while also celebrating a discovery offshore Equatorial Guinea.
