Drilling Activity Summary


Tullow Oil has tested exploration well #1-Joe and according to the London-based company, has opened a new Upper Tertiary oil play in offshore Guyana’s Guyana Basin. The well was drilled to 2,175 m and is in 780 m of water. Evaluation of logging and sampling data has confirmed that the venture encountered 14 m of net oil pay in high-quality, oil bearing sandstone reservoirs of Upper Tertiary age. The #1-Joe is the first oil discovery to be made in Upper Tertiary and de-risks the petroleum system in the west of the Orinduik block, where a number of Tertiary and Cretaceous age prospects have been identified. The data from #1-Joe will be evaluated with a previous discovery at #1-Jethro. A follow-up well is planned at #1-Carapa on the Kanuku license. Tullow is the operator of the block with a 60% interest, along with partners Total (25%) and Eco Atlantic (15%).
