In Mauritania, Tullow has exploration, development and production activities across a number of offshore licences. Tullow has a significant exploration acreage position extending along some 750 km of coastline and a small producing interest in the Chinguetti oil field.
EXPLORATION & APPRAISAL
Tullow identified a number of offshore exploration opportunities in Mauritania building on the knowledge it gained from the successful Ghana campaign and began to build on its existing acreage position. In June 2012, Tullow signed the new C-18 exploration licence which lies directly west of its existing Block 7 licence. Tullow’s further enhanced its exploration acreage with the signing of the shallow water C3 licence in April 2013.
Tullow commenced a two well exploration programme in 2013/14. In 2013, Frégate-1 in Block 7 encountered up to 30 metres of net gas-condensate and oil pay. In 2014, Tapendar-1 in Block C-10 was a dry hole and was plugged and abandoned. Tullow has been reviewing and integrating this well data to determine future drilling targets which are likely to include opportunities in the shallower shelf play.
Seismic activity has continued over the past few years and is an important part of the long term exploration strategy to quantify the exploration potential and to build up a future prospect inventory. In June 2014, a 1,786 km 2D seismic line was acquired as part of the C-18 licence work programme. Acquisition of further 2D seismic was in progress during Q1 2015 in the C-3 licence where approximately 1,800 km of data had already been shot in Q4 2014. In February 2015, Tullow agreed to farm down a 40.5% interest in the C-3 licence to Sterling Energy with Tullow retaining 49.5%.
DEVELOPMENT & OPERATIONS
Production first began from the offshore Chinguetti in 2003 which is now operated by Petronas. Currently the field makes a very small contribution of around 2% to Tullow’s overall Group production and this is set to reduce as a percentage of Group volumes as production from Ghana continues to grow.
Whilst significant progress was made on the Banda development project in 2014, following a review of the Group’s capital budget, it was decided that funding would not be allocated to Banda in 2015. The Government of Mauritania and the other key stakeholders have been informed and are working on alternative approaches to completing the upstream section of the project.
