||1H 2013 Exploration and appraisal wells
||1H 2013 Success rate
In 2011, Tullow's E&A drilling activity was focussed on Uganda where 8 out of 9 wells successfully encountered hydrocarbons. By the end of 2012 more than 50 wells had been drilled in Uganda with only 5 unsuccessfully encountering hydrocarbons. Tullow is now leveraging the knowledge it has gained in Uganda and is applying that to the East African Rift Basin where it has acquired around 100,000 sq km of acreage in onshore Kenya and Ethiopia. The first well to test this new basin, Ngamia-1, successfully encountered over 200 metres of net oil pay and the second well, Twiga South-1, also made an oil discovery in October 2012. This was followed by a third successful well in the Lokichar Basin at Etuko-1, in July 2013 followed by a fourth, Ekales-1, in September 2013.
Significant seismic activity is taking place across both Kenya and Ethiopia with a major programme of over 10 E&A wells expected during 2013.
In August 2012, Tullow farmed in to area 2 and 5 in the Rovuma Basin offshore Mozambique and to date 2 exploration wells have been drilled in 2013.
