About Tullow in Kenya

View Kenya Map

Tullow has a track record of discovering significant oil resources in East Africa. The Group first started exploring in Uganda in 2006, successfully opening the Lake Albert Rift Basin, which has discovered resources of some 1.7 billion barrels of oil. Tullow has taken its knowledge and understanding of the geology in Uganda across into neighbouring Kenya. Since 2012, Tullow’s successful exploration and appraisal drilling campaigns in Kenya have resulted in the opening of a second new tertiary rift play in the South Lokichar Basin. Following a full assessment of all the exploration and appraisal data, Tullow estimates that the South Lokichar basin contains the following recoverable resources: 240 – 560 – 1,230 mmbo (1C–2C–3C) from an overall discovered STOIIP of up to 4 billion barrels. 


The Ngamia-1 exploration well in Kenya marked the start of a significant programme of drilling activities across the acreage. In 2012, the Ngamia-1 well successfully encountered over 200 metres of net oil pay, the second East Africa onshore tertiary rift basin opened by Tullow. This has since been followed by further exploration success in the South Lokichar Basin at the Amosing, Twiga, Etuko, Ekales-1, Agete, Ewoi, Ekunyuk, Etom, Erut and Emekuya oil accumulations. 

A total of 21 appraisal wells have been drilled in the South Lokichar basin and Tullow has also conducted extended well tests, water injection tests, well interference tests and water-flood trials, all of which have proved invaluable for planning the development of the oil fields.

Development planning 

Tullow and its Joint Venture Partners have proposed to the Government of Kenya that the Amosing and Ngamia fields should be developed as the Foundation Stage of the South Lokichar development. This stage would include a 60,000 to 80,000 bopd Central Processing Facility (CPF) and an export pipeline to Lamu. This approach brings significant benefits as it enables an early FID of the Amosing and Ngamia fields taking full advantage of the current low-cost environment for both the field and infrastructure development and provides the best opportunity to deliver First Oil in a timeline that meets the Government of Kenya (GoK) expectations. The installed infrastructure from this initial phase can then be utilised for the optimisation of the remaining South Lokichar oil fields, allowing the incremental development of these fields to be completed at a lower unit cost post-First Oil.

The Foundation Stage is currently planned to involve an initial 210 wells through 18 well pads at Ngamia and 70 wells through seven well pads at Amosing. This stage will target volumes of around 210 mmbo of the total estimated 2C resources of 560 mmbo and a plateau rate of 60,000 to 80,000 bopd. The incremental development of the remaining 2C resources and the significant upside potential is expected to increase plateau production to 100,000 bopd or greater. It is anticipated that the FEED and baseline Environmental and Social Impact Assessments (ESIA) for the foundation development will commence in the second quarter of 2018, with FID targeted for 2019 and First Oil for 2021/22. Total gross capex associated with the Foundation Stage is expected to be $2.9 billion, of which $1.8 billion is investment in the upstream and $1.1 billion is for the pipeline. 

Tullow and its Joint Venture Partners, following the extended election period, have re-engaged with representatives of the Government of Kenya on the overall approach and timelines for progressing the development.

Early Oil Pilot Scheme (EOPS)

The EOPS Agreement between the Joint Venture Partners and the Government of Kenya was signed on 14 March 2017 allowing all EOPS upstream contracts to be awarded. Initial injectivity testing has started at Ngamia-11 and oil production and water injection facilities are being constructed in the field ready to commence production/injection in the first quarter of 2018. Oil produced is being initially stored until all necessary consents and approvals are granted and work is completed for the transfer of crude oil to Mombasa by road.


Our history in Kenya

Tullow entered Kenya in 2010, after signing agreements with Africa Oil and Centric Energy to gain a 50% operated interest in five onshore licences; 10BA, 10BB, 10A, 12A and 13T. In 2012, Tullow farmed in to onshore Block 12B with 50% and increased its interest in Block 12A to 65%. Since then our interest in Block 10A has been relinquished and in October 2015. Tullow currently has a 50% interest in Blocks 10BA, 10BB, 12A, 13T & 100% in Block 12B.
