Tullow Oil PLC will restart development drilling in the TEN oil fields offshore Ghana with the Maersk Venturer drillship, for which it has signed a contract for up to 4 years.
It also will use the ship for drilling in Jubilee oil field.
Drilling in the TEN development area was suspended by a border dispute between Ghana and Ivory Coast, which was settled in the International Tribunal of the Law of the Sea last September (OGJ Online, Sept. 25, 2017).
The first well in the revived TEN program will be a production well in Ntomme field. It will be followed by a Jubilee production well. The rest of the schedule is under development.
Tullow said it and partners are considering use of a second rig. The other TEN fields are Tweneboa and Enyenra.
Tullow expects the TEN fields to produce an average 64,000 b/d gross this year.
In the fourth quarter of 2017, Tullow signed an agreement with the government of Ghana to sell associated gas from the fields. It expects gross gas sales of 4,200 boe/d this year.
Partners in the TEN development area are Kosmos, Anadarko, Ghana National Petroleum Corp., and Petro SA.
