LONDON -- Tullow Oil has made an oil discovery with the Odum-1 exploration well off Ghana in 955 m (3,133 ft) of water. The well, drilled to 3,387 m (11,112 ft) deep, encountered a gross oil column of 60 m (197 ft) and 22 m (72 ft) of net pay. Samples from the reservoir indicate an oil gravity of approximately 29° API.
Odum-1 will be completed and suspended as a future development well. TheSonga Saturn drillship will move to Mahogany-2, the next appraisal well on the Jubilee field.
Meanwhile, due to persistent borehole instability, Tullow has decided to suspend the Ngassa-1 exploration well and re-drill it from an alternate location.
