Nov 6 (Reuters) - Kosmos Energy Ltd said it expects to resume development drilling on Ghana's multi-billion dollar TEN deepwater oil and gas project in early 2018, rather than around the end of this year as it previously expected.
In September, the International Tribunal for the Law of the Sea drew an ocean boundary favouring Ghana in a maritime border dispute with its neighbour Ivory Coast, opening the way for development drilling to resume on the TEN project.
The decade-old row between the two West African neighbours has slowed the development of oilfields.
Tullow Oil Plc, Anadarko Petroleum Corporation , Ghana National Petroleum Corporation and PetroSA also have stakes in the TEN project.
Kosmos also estimated it would require two shutdowns in 2018, resulting in about four weeks of downtime, to stabilise the turret of the floating production, storage and offloading vessel at its Jubilee field in Ghana.
An issue with the turret bearing was identified in February 2016. The company had previously planned a shut down of 5-8 weeks in late 2017.
Planning for the rotation of the vessel in the Jubilee field is also ongoing, with work expected to begin around year-end 2018, Kosmos said.
During the third quarter of 2017, Kosmos said its gross sales volumes from Ghana averaged about 160,000 barrels of oil per day (bopd), including volumes from the Jubilee and TEN fields which averaged about 100,000 bopd and 60,000 bopd, respectively.
