原标题：Stena钻井船到达秘鲁 中国石化新闻网讯 据1月10日Offshore Energy报道，澳大利亚能源公司Karoon Energy表示，在秘鲁通贝斯盆地Z-38区块钻探马里纳1号探井之前，Stena4号钻井船已经抵达秘鲁卡亚俄港。 Karoon公司与钻探承包商Stena drilling和图洛石油公司签署了具有约束力的协议，将于2019年11月为Karoon公司的Marina-1井承租Stena Forth钻井船。该钻井船已经在图洛在圭亚那近海的运营区块内钻探了两口井。 Karoon是运营商，在Z-38区块拥有40%的净权益。该公司此前表示：Stena Forth钻井船将在卡亚俄港停留一到两周，补充燃料并更换船员，然后继续前往马里纳1号井处。 该公司预计，这艘船将在未来几周内通过海关检查，并获得最终许可。预计该井将在2020年1月的最后一周开使钻探。 Marina 油田预期资源总储量达2.56亿桶石油(净储量为1.02亿桶)。 Marina勘探区块由一个大型断层封闭结构组成，目标位于水下900米至2900米的多个层面。目标位于第三纪上新世La Cruz到Cardalitos地层。 根据Karoon的说法，三维地震可以很好地定义结构。附近的烃类渗漏表明流动的烃类是存在的，受地震AVO异常的支持，表明Marina区块存在石油。 邹勤 摘译自 Offshore Energy 原文如下： Stena drillship arrives in Peru ahead of Karoon well Australia’s Karoon Energy has said that the Stena Forth drillship has arrived in the Port of Callao Lima Peru ahead of drilling the Marina-1 exploration well located in Block Z-38 Tumbes Basin, Peru. Karoon executed binding agreements with drilling contractor Stena Drilling and oil company Tullow Oil to contract the Stena Forth drillship for Karoon’s Marina-1 well in November 2019. The drillship has already drilled two wells for Tullow offshore Guyana. Karoon is the operator and has a 40% net interest in Block Z-38. The company said in an update on Thursday that the Stena Forth would remain at the Port of Callao for one to two weeks to refuel and change the crew before continuing on to the Marina-1 well location. “Karoon expects the vessel to clear customs and final permits to be received over the coming weeks. The well is expected to spud during the last week of January 2020,” the company said. The Marina prospect has a gross prospective resource best estimate of 256 million barrels of oil (net to Karoon 102 million barrels). The Marina prospect comprises a large fault-bounded structure with targets at multiple levels from 900m subsea to 2900m. The targets are in the Tertiary Pliocene La Cruz to Cardalitos formations. According to Karoon, the structures are well defined by 3D seismic. Nearby hydrocarbon seeps demonstrate that migrating hydrocarbons are present, supported by seismic AVO anomalies indicative of trapped oil at Marina, Karoon said. |
