Tullow Discovers Oil, Gas-Condensate At Tweneboa-2, Ghana

UK-based company Tullow Oil has discovered an oil and gas-condensate field on the Tweneboa-2 well of

A combined hydrocarbon column of at least 350mt has been established between the lowest known oil in Tweneboa-2 and the top of the gas-condensate at Tweneboa-1. It is hoped additional drilling will reveal a turbidite fan system.

After the completion of logging operations, the well will be deepened to test further exploration potential beneath the Tweneboa field. The well will then be suspended for future use in appraisal and development, the company said.

The Atwood Hunter semi-submersible drilled Tweneboa-2 in the Deepwater Tano block to an interim depth of 3,860mt in water depths of 1,321mt. On completion of operations on Tweneboa-2, the rig will move to drill the Dahoma-1 exploration well in the West Cape Three Points block east of the Jubilee field.

Tullow (49.95%) operates the Deepwater Tano licence and is partnered by Kosmos Energy (18%), Anadarko Petroleum (18%), Sabre Oil & Gas (4.05%) and the Ghana National Petroleum Corporation (GNPC) (10% carried interest).
