Tullow Oil plc (Tullow) announces that the Joe-1 exploration well has successfully opened a new Upper Tertiary oil play in the Guyana basin. This discovery follows the company’s first successful well offshore the South American country – Jethro-Lobe – announced on August 12.
The Joe-1 exploration well was drilled by the Stena Forth drillship to a Total Depth of 2,175 metres in water depth of 780 metres. Evaluation of logging and sampling data has confirmed that Joe-1 has encountered 14 metres of net oil pay in high-quality oil-bearing sandstone reservoirs of Upper Tertiary age. Joe is the first oil discovery to be made in the Upper Tertiary and de-risks the petroleum system in the west of the Orinduik block, where a significant number of Tertiary and Cretaceous age prospects have been identified.
Tullow and its Partners will now evaluate data from the Joe-1 discovery alongside data from the Jethro-1 discovery announced in August 2019 and await the outcome of the Carapa well to determine the optimal follow-on exploration and appraisal programme.
Commenting on the discovery, Director of Guyana’s Department of Energy, Dr. Mark Bynoe said, “The Co-operative Republic of Guyana continues to be encouraged by the prolific rate of discovery in our country. Every Guyanese can be assured that the Government will continue to work conscientiously to pursue the most effective and efficient marketing strategies of Guyana’s crude entitlement to transform our economy and to implement sustainable development programmes from which all Guyanese can benefit.
“Guyana’s future is bright but more importantly, the time is ripe for all Guyanese to focus on how they want to see their oil revenues spent and invested”, Dr. Bynoe said.
The non-operated Carapa-1 well on the Kanuku licence (Tullow 37.5%) is scheduled to commence drilling in late September with the Rowan EXL II jack-up rig and will test the Cretaceous oil play with a result due in the fourth quarter of 2019.
Joe-1 was drilled on the Orinduik licence, offshore Guyana by Tullow’s wholly owned subsidiary Tullow Guyana B.V.
Tullow Guyana B.V. is the operator of the Orinduik block with a 60% stake. Total E&P Guyana B.V. holds 25% with the remaining 15% being held by Eco (Atlantic) Guyana Inc. On completion of operations, the Stena Forth drill ship will depart Guyana and return to Ghana.
