Tullow Confirms Greater Tweneboa Area Resource Potential with Gas Discovery

Tullow's Tweneboa-3 appraisal well has encountered gas condensate in excellent quality sandstone reservoirs; and drilling results, wireline logs and fluid samples from the well confirm the greater Tweneboa area resource base potential.

The well was planned with two deviated boreholes to test separate areas of the Tweneboa field, stated the operator. The first leg was drilled to calibrate the potential of an area with a weak seismic response. This leg encountered thin reservoir sands and about 30 feet (9 meters) of gas condensate pay. The well was then sidetracked about 1,804 feet (550 meters) west, targeting the Ntomme anomaly, an area of strong seismic response. This leg encountered a gross vertical reservoir interval of about 213 feet (65 meters) containing 112 feet (34 meters) of net gas condensate pay in two zones of high-quality stacked reservoir sandstones.

Currently, work is underway to integrate seismic, pressure and hydrocarbon data in order to progress development options for the Tweneboa and Enyenra (Owo) fields in the greater Tweneboa area. Drilled by the Deepwater Millennium drillship, the well reached a total depth of 12,815 feet (3,906 meters) in a water depth of 5,253 feet (1,601 meters).

Once operations are completed, the well will be suspended for future use in the field's development. The rig will remain in the block to drill the top-hole section of the Tweneboa-4 appraisal well. Tweneboa is located in the Deepwater Tano License offshore Ghana on Block 2, and is operated by Tullow Oil.
