中国石化新闻网讯 据全球石油新闻网9月28日丹佛报道，曾被认为是美国下一个二叠纪盆地的SCOOP/STACK的钻井活动本周放缓到了近3年来从未见到过的速度。 美国能源业界著名咨询公司Enverus/DrillingInfo近日公布的统计数据显示，邻近的俄克拉荷马州中部页岩盆地的在用钻机数又减少了4部，减少到了57部。 俄克拉荷马州中部页岩盆地近期钻探活动的放缓伴随着今年油价的走软。最近几个月，基准的西德克萨斯中质原油(WTI)价格平均每桶在55至57美元左右。这些价格比2018年末的近75美元/桶高点有所回落。 仅在今年，在SCOOP/STACK的在用钻机数就下降了近44%，从1月份的105部在用钻机数高点暴跌。2018年第二季度，俄克拉荷马州中部页岩盆地的钻井速度已经达到其顶峰，在用钻机数一度达到了116部。 然而，今年更高的钻井成本、不同的岩石质量以及越来越难以预测、往往令人失望的回报率使得切萨皮克公司、西马雷克斯公司、德文能源公司、马拉松石油公司等主要油田拥有者纷纷停止钻探活动，尤其是在 Kingfisher County的油田。 统计数据显示，今年9月份，在STACK的半周期内部收益率估计在17%，而在SCOOP的半周期内部收益率估计不到11%。 李峻 编译自 全球石油新闻 原文如下： SCOOP/STACK drilling activity tumbles to three-year low Drilling activity in the SCOOP/STACK - a play once considered to be the next Permian Basin - slowed this week to a pace not seen in nearly three years. Rig count across the neighboring central Oklahoma shale basins dipped by another four, falling to just 57, data published Thursday by Enverus/DrillingInfo showed. The recent slowdown in drilling there has accompanied weaker oil prices this year, which in recent months have averaged around $55-$57/b at the benchmark WTI. Those prices are down from late 2018 highs at nearly $75/b. In 2019 alone, the number of active drilling platforms in the SCOOP/STACK has declined by nearly 44%, falling from a January high of 105 rigs. The pace of drilling in central Oklahoma had already reached its zenith in the second quarter 2018 when the rig count there briefly hit 116. This year, though, higher well costs, varying rock quality and increasingly unpredictable, often disappointing, rates of return have seen major acreage holders, such as Chesapeake, Cimarex, Devon, Marathon and others, move in droves to pause their drilling activity - particularly in the STACK of Kingfisher County. In September, half-cycle internal rates of return in the STACK were estimated at 17% and in the SCOOP at less than 11%, data shows.
