News in Brief

Tullow has submitted the TEN field Plan of Development to the Government of Ghana

The acid stimulation of certain Phase 1 production wells in the Jubilee field has proven to be successful and gross production has increased from 63,000 bopd at the middle of 2012 to a recent production rate of around 85,000 bopd, in line with expectations.

In addition, the Jubilee Phase 1A development project is progressing well with five of the eight wells drilled. All of the wells have encountered good quality reservoir on prognosis. Following extensive unplanned maintenance work on the Sedco Energy rig, well completion operations commenced at the end of October and Phase 1A production is expected to begin from one well in the near future. By the end of the year, an additional Phase 1A producer is expected to be brought on line and a further acid stimulation on a Phase 1 well is expected to be completed. This work is expected to take gross Jubilee production above 90,000 bopd by the end of the year and capacity production for the FPSO is expected to be reached in the first half of 2013 as further Phase 1A production and injection wells come on line.

In the second half of 2012, the Tweneboa, Enyenra and Ntomme (TEN) project made good progress and Tullow and partners submitted the Plan of Development to the Minister of Energy in early November 2012. The development is being designed with sufficient flexibility to allow both TEN resources and nearby discoveries to be tied into an FPSO. Following the Wawa discovery on the Deepwater Tano block in July 2012, an appraisal programme is now being evaluated. The Okure exploration well to the south of TEN is currently being drilled and a result is expected in the coming weeks. The rig will then move to drill the Sapele exploration well to the southwest of Jubilee. These wells will complete the exploration campaign on the block before the licence period ends in January 2013.

Production performance elsewhere in West & North Africa is in line with expectations. Three work-overs and one new production well have been successfully completed on the Ceiba field in Equatorial Guinea this year and five production wells are planned to increase current production levels. Appraisal and infill drilling has been very successful on Tullow’s Gabon assets during the year. The Tchatamba-South B9 well has been drilled and is now producing 1,100 bopd net and the more recent Limande-8 Hz development well is also producing 1,400 bopd net to Tullow. Production from the M’Boundi field in Congo (Brazzaville) has remained stable during the year following sustained water injection and the continued work-over and infill drilling campaign. Two recent wells successfully opened up and appraised a southeast extension of the field.

In Mauritania, the Banda gas field has been declared commercial and it is planned that the field will supply a power development. In September 2012, in advance of the major exploration campaign scheduled to commence in Q1 2013 across various licences, the second part of a 3D seismic acquisition in Block C-2 was completed.

Tullow has also entered into an exclusive negotiation with Hyperdynamics Corporation in respect of a potential farm-in by Tullow into a concession offshore Guinea.
