Owo-1 wildcat intersects 'significant' column of light oil

London-listed Tullow Oil said the Owo-1 wildcat in the Deep-water Tano licence offshore Ghana had intersected a ‘significant’ column of light oil, establishing Owo as a major new oil field.

Tullow said Owo-1 was located in a water depth of 1428 metres and drilled to a final depth of 3891 metres.

The well encountered 53 metres of net oil pay in two zones of high quality stacked reservoir sandstones over an interval of 154 metres.

Tullow said following the completion of logging operations the well would be sidetracked 600 metres east to provide additional information on lateral reservoir distribution and to intersect a deeper part of the Owo channel system.

After completing work on Owo-1, Tullow said it planned to commence work on the Onyina-1 exploration well which will target a large channel system between the Tweneboa and Jubilee fields.

Tullow has a 49.95 per cent stake in the Deep- water Tano licence and is partnered by Kosmos Energy Ghana (18 per cent), Anadarko Petroleum (18 per cent), Sabre Oil & Gas (4.05 per cent) and the Ghana National Petroleum Corporation (GNPC) (10 per cent carried interest).
