Tullow Oil PLC has started oil production from Tweneboa, Enyenra, and Ntomme (TEN) fields offshore Ghana.
Tullow expects oil production to ramp-up gradually towards the Prof. John Evans Atta Mills floating production, storage, and offloading vessel’s capacity of 80,000 b/d of oil through the remainder of this year. The firm estimates TEN average annualized output for the year will be 23,000 bo/d gross and 11,000 bo/d net.
The first TEN discovery was made in 2009. The government of Ghana approved the project’s plan of development in 2013.
Tullow is operator of the TEN fields with 47.175% interest. Partners are Anadarko Petroleum Corp. with 17%, Kosmos Energy Ltd. 17%, Ghana National Petroleum Corp. 15%, and PetroSA 3.875%. Tullow also is operator of offshore Ghana’s Jubilee field, which has been on stream since 2010.
