石油设备网讯 据烃加工在线6月17日消息称，联合杰克石油公司是一家专注于英国陆上油气生产、开发和勘探的公司，该公司宣布了最近在英国西约克郡西牛顿A-2常规评估井的初步结果，该井位于PEDL 183内，由Rathlin能源(英国)有限公司运营。联合杰克公司持有该许可证16.665%的权益，包括西牛顿A-1发现井和西牛顿A-2鉴定井。
西牛顿A-2井于2019年4月26日开钻，2019年6月9日达到2061米的总深度（TD）。从主要目标层成功提取岩心28米，Kirkham Abbey组和所有计划的测井作业均已完成。
在Kirkham Abbey地层中发现了65米的纯烃饱和层段，表明存在大量的油气聚集，包括一个重要的液体组分。
钻井作业现在已经结束，生产套管已经开始作业，准备对这一延长的时间间隔进行测试，并已获得规划同意。拟议的延长试井将确定流量，并将有助于确定西牛顿项目未来的钻井和开发计划。测试预计将于2009年第3季度开始。
西牛顿A-2井的原始岩石物理资料与西牛顿A-1常规发现井的结果正相关。在西牛顿A-2井钻探之前，德勤编制的一份称职人士报告对应急资源的最佳估计为1890亿立方英尺天然气当量。在进行进一步的岩心和测井分析后，将首先更新产量预期，然后再进行扩展试井。
该井还遇到了深层Cadeby地层中的烃源岩，这是一个次生目标。该交点与西牛顿A-1井相吻合，西牛顿A-1井的岩心为饱和油。该地层计划在未来与西牛顿-B井位相交，预预计将进行最优储层开发，规划许可已经到位。

Union Jack Oil announces gas discovery in West Newton, UK
Union Jack Oil, a UK-focused onshore hydrocarbon production, development and exploration company, has announced positive preliminary results in respect of the recently drilled West Newton A-2 conventional appraisal well in West Yorkshire, UK, located within PEDL 183 and operated by Rathlin Energy (UK) Ltd. Union Jack holds a 16.665% interest in this licence containing the West Newton A-1 discovery well and West Newton A-2 appraisal well.
The West Newton A-2 well was spudded on 26 April 2019 and on 9 June 2019 reached a total depth (TD) of 2061 m. 28 m of core has been successfully extracted from the primary target, the Kirkham Abbey formation and all planned logging operations have been completed.
A net 65 m hydrocarbon saturated interval has been encountered from within the Kirkham Abbey formation indicating a substantial hydrocarbon accumulation, including a significant liquids component.
Drilling operations have now concluded, and production casing has been run in preparation for testing of this extended interval, for which planning consent has been received. The proposed extended well test will establish flow rates and will help determine the future drilling and development programme at the West Newton project. Testing is expected to commence in 3Q19.
The initial petrophysical data obtained from the West Newton A-2 well correlates positively with the results from the West Newton A-1 conventional discovery well. Prior to the drilling of the West Newton A-2 well, a Competent Person`s Report compiled by Deloitte, had a Best Estimate Contingent Resource of 189 billion ft3 of gas equivalent. Volume expectations will initially be updated following further core and log analysis, then again following the extended well test.
The well also encountered hydrocarbon shows within the deeper Cadeby formation, a secondary target. The intersection is consistent with the West Newton A-1 well from which an oil saturated core was recovered. The formation is planned to be intersected in the future from the West Newton-B well location, where optimal reservoir development is expected, and planning permission is already in place.
