油气生产与开发公司Independent Oil and Gas plc近日宣布其已完成了位于北海北部9/21a区块的Skipper首井钻探作业，许可证编号为P1609，IOG对其拥有100%的所有权与经营权。
该井的垂直钻探总深度达到了5578英尺，整个过程保证了零安全事故的发生，实现了获取Skipper油层高质量石油样本的主要目标，也优化了Skipper的油田开发方案。IOG的管理层预计该样品油的粘度范围在50cP与150cP之间，这比Competent Persons Report (CPR)预测的结果要理想得多。样本已被送往亚伯丁检测中心进行检测，预计2016年9月就会得到初步的结果。一旦资产被批准，Skipper油田开发区将缩减油井数量，进而改善开发区经济。

Independent Oil and Gas plc, the development and production focused Oil and Gas Company, is pleased to announce the completion of its first operated appraisal well on the Skipper oil discovery which lies in Block 9/21a in licence P1609 in the Northern North Sea, of which IOG is 100% owner and operator.
The well was successfully drilled to a total vertical depth of 5,578ft with no safety incidents and achieved its primary objective of retrieving good quality reservoir condition oil samples from the Skipper reservoir in order to optimise the Skipper field development plan. The oil viscosity of the samples appears likely to be within the 50cP – 150cP range expected by the IOG management, much better than Competent Persons Report (‘CPR’) estimates. The samples are now being analysed in Aberdeen, with initial results expected in September 2016. Should these properties be confirmed the development of the Skipper field will require fewer development wells thereby improving the development economics.
The well’s secondary objective, to drill two mapped reservoir structures beneath the Skipper oil field in the Lower Dornoch and Maureen formations is now complete. The well did not encounter hydrocarbons in these horizons and will now be plugged and abandoned. The initial licence commitment on P1609 is to drill a well into the Maureen formation to a minimum depth of 1,700m (5,578ft). This commitment has therefore now been fulfilled.
