LONDON, June 11 -- Tullow Oil PLC has tested 5,200 b/d of 36° oil and 5.3 MMcfd of associated natural gas from its Mahogany-2 well on Jubilee field off Ghana. The appraisal well is part of its program to assess the productivity and reservoir model.

The well, drilled by the Songa Saturn drillship, reached 3,443 m TD in 1,080 m of water on the West Cape Three Points license. Tullow said it was confident that Jubilee could flow more than 20,000 b/d when it comes on stream in 2010 (OGJ Online, May 26, 2008, p. 20).

Tullow Chief Executive Officer Aidan Heavey said the results support the decision by the Jubilee partnership to fast-track the project.

A single zone covering an interval of 17 m was tested through a 40/64-in. choke, resulting in a flowing tubing head pressure of 1,540 psi, Tullow said.

Later this year, the Blackford Dolphin and Eirik Raude deepwater rigs will carry out an appraisal, development, and exploration drilling program in both the West Cape Three Points and the Deepwater Tano licenses.
