Again, Tullow hits oil in Ghana

29 September 2011, Sweetcrude, Accra – London-listed Tullow Oil says it has encountered hydrocarbons in the Enyenra-3A appraisal well in the Deepwater Tano licence off Ghana.

Enyenra-3A was drilled to a total depth of 4031 metres, in water depths of 1102 metres, and testing showed the well intersected 17 metres of 35 degree API oil in high quality sandstone reservoirs.

Tullow added pressure data confirmed a continuous oil column of at least 365 metres and the oil at Enyenra-3A was in static pressure communication with both the Owo-1 discovery well and the Enyenra-2A appraisal well, which lie 6.5 kilometres and 14 kilometres to the south respectively.

Tullow’s exploration director, Angus McCoss, said: “This excellent result demonstrates that we are close to declaring the Enyenra and Tweneboa development commercial.”

“Although the ultimate extent of the fields are yet to be fully determined, confirmation of this up-dip extension and long oil column in Enyenra is very encouraging.”

Following the completion of drilling operations, Tullow will deploy pressure gauges in Enyenra-2A and Enyenra-3A to determine reservoir connectivity prior to flow testing the Enyenra field later this year.

Tullow said it planned to drill the Enyenra-4A well later this year, which will be lie about 6.8 kilometres south of Enyenra-2A and over 20 kilometres down-dip from the Enyenra-3A well, to further appraise the down-dip extent of the field.

Tullow is operator of the Deepwater Tano licence and holds a 49.95% stake along with partners Kosmos Energy and Anadarko Petroleum each on 18%, Sabre Oil & Gas holding 4.05% and the Ghana National Petroleum Corporation (GNPC) holding a 10% carried interest.
