The Ghana National Petroleum Corporation (GNPC), has announced
the Okure-1 exploration well, drilled in the Deepwater Tano licence offshore Ghana encountered an oil bearing reservoir in a secondary objective.
The well, which was drilled to a total depth of 4,511 metres in water depth of 1,657 metres, encountered non-reservoir quality formations at the main objective levels below the Tweneboa, Enyenra and Ntomme cluster of discoveries.
However, the well discovered approximately 5 metres of net oil pay of Turonian age sandstone within an overlying secondary objective. Light oil with a 40 degree
API was recovered from this interval.
Integration of wireline logs and pressure data indicates that this oil accumulation is not connected to other hydrocarbon discoveries in the licence area.
According to the Director of Operation, Mr. Thomas Manu, “the small oil accumulation is encouraging in the license area and will be investigated further to establish its commerciality and potential increase in the hydrocarbon reserves of the block”.
Tullow operates the Deepwater Tano licence and the Jubilee Field and is partnered by Kosmos Energy, Anadarko Petroleum, PetroSA and the Ghana National Petroleum Corporation (GNPC).
