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 Basins 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 important oil discovery in October 2012. Five further discoveries have been made in the basin to-date with over 600 mmbo being discovered.
Significant seismic activity is taking place across both Kenya and Ethiopia with a major programme of E&A wells planned during 2014 and 2015.
In August 2012, Tullow farmed in to area 2 and 5 in the Rovuma Basin offshore Mozambique with 2 exploration well drilled in 2013.
With over 120 leads and prospects across multiple basins there is significant prospectivity and follow-up potential in this pioneering campaign that has the potential to open up a significant new oil province in East Africa.
Appraisal and testing
Our licences continue to deliver multiple and attractive oil appraisal opportunities in support of our preparations for basin development.
