据世界石油网伦敦报道，英国著名的独立油气公司图洛石油公司(Tullow Oil PLC)经营的Joe-1勘探井日前在圭亚那盆地成功开辟了一个新的上第三纪石油远景区。
Joe-1勘探井的钻井作业由《Stena Forth》号钻井船完成，此井完钻时总深度为2175米，水深780米。测井评价和取样数据证实，在上第三纪优质含油气砂岩储层中，Joe-1勘探井在钻进中先后钻遇了14米厚的净含油层。Joe-1井是在上第三系地层中获得的第一个石油发现，这个石油发现降低了奥林杜伊克区块西部石油系统的风险，该区块确定了大量第三纪和白垩纪年代的远景构造。
图洛石油公司及其合作伙伴现在将评估Joe-1发现井的数据以及今年8月宣布的 Ethro1发现的数据，并等待Carapa油井的结果，以确定最佳的后续勘探和评估计划。
Joe -1勘探井是由图洛石油公司旗下的全资子公司图洛石油圭亚那公司在位于圭亚那近海的奥林杜伊克许可证区块内钻探的。图洛石油圭亚那公司是奥林杜伊克区块的运营商，拥有60%的股份。法国道达尔E&P 圭亚那公司持有25%的股份，其余15%股份由埃科 (大西洋) 圭亚那公司持有。

Tullow opens a new oil play offshore Guyana
Tullow Oil’s Joe-1 exploration well has successfully opened a new Upper Tertiary oil play in the Guyana basin.
The Joe-1 exploration well was drilled by the Stena Forth drillship to a Total Depth of 2,175 meters in water depth of 780 meters. Evaluation of logging and sampling data has confirmed that Joe-1 has encountered 14 meters of net oil pay in high-quality oil bearing sandstone reservoirs of Upper Tertiary age. Joe-1 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 program.
The non-operated Carapa-1 well on the Kanuku license (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 license, 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.
