據(jù)油價網(wǎng)2021年6月28日報道，美國能源信息署(EIA)估計，自去年6月達到峰值以來，美國頁巖探區(qū)已開鉆但未完鉆 (DUC)井數(shù)量已經(jīng)下降了27%。

　　DUC井可以讓勘探和生產(chǎn)公司以更低的成本開采原油和天然氣，所以DUC井數(shù)量自去年6月達到峰值以來下降27%也就不足為奇了。 當時，由于低油氣價格以及全球石油需求在新冠肺炎疫情大流行期間的暴跌，運營商關閉了油氣生產(chǎn)。 自去年年初新冠肺炎疫情爆發(fā)以來，勘探和生產(chǎn)公司已經(jīng)收緊了鉆井活動的支出，他們正在開發(fā)更多的DUC井以維持產(chǎn)量。

　　據(jù)EIA估計，去年6月，美國DUC井存貨量達到了8874口的峰值。 近一年后，也就是今年5月，EIA估計，美國在7個主要的致密油和頁巖氣盆地(二疊紀, 鷹福特、阿納達科、 阿帕拉契亞、巴肯、尼奧巴拉和海恩斯維爾)約有6521 口DUC井。

　　EIA估計，從去年6月到今年5月，美國的DUC井總數(shù)下降了27%或2353口。

　　EIA說：“自COVID-19大流行開始以來，勘探和生產(chǎn)公司已經(jīng)削減了資本支出，部署了更少的鉆機，并減少了石油和天然氣產(chǎn)量，以應對需求下降和價格下跌。 DUC井幫助作業(yè)者以更低的成本生產(chǎn)石油和天然氣。”

　　EIA 6月中旬發(fā)布的最新鉆井生產(chǎn)力報告顯示，4月至5月間，美國DUC井數(shù)量減少了247口。 該報告還顯示，來自美國7個最高產(chǎn)頁巖盆地的頁巖產(chǎn)量將環(huán)比日增3.8萬桶。

　　Number Of U.S. Drilled But Uncompleted Wells Drops 27% In A Year

　　The number of drilled but uncompleted wells (DUCs) in the U.S. shale patch has declined by 27 percent since the peak in June 2020, the Energy Information Administration (EIA) has estimated.

　　DUCs allow exploration and production companies to pump crude oil and natural gas at a lower cost, so it’s no surprise that the number of DUCs has dropped since the peak in June 2020. Back then, operators shut in production because of the low oil and natural gas prices and the crash in global oil demand in the pandemic. E&P firms have tightened spending on drilling activity since the COVID outbreak early last year, and they are tapping more DUCs to maintain production rates.

　　According to EIA estimates, the U.S. inventory of DUCs peaked at 8,874 such wells in June 2020. Nearly a year later, in May 2021, the most recent month available, the EIA estimated that the United States had about 6,521 DUCs in the seven major tight oil and shale natural gas basins—the Permian, Eagle Ford, Anadarko, Appalachia, Bakken, Niobara, and Haynesville.

　　Currently, almost 40 percent of DUCs, or 2,616 DUCs, are in the Permian Basin.

　　The total number of DUCs in the U.S. fell by 27 percent, or by 2,353 DUCs, between June last year and May this year, the EIA has estimated.

　　“Since the COVID-19 pandemic began, exploration and production (E&P) companies have cut capital expenditures, deployed fewer rigs, and reduced oil and natural gas production in response to lower demand and lower prices. DUCs help operators produce oil and natural gas at a lower cost,” the EIA noted.

　　The EIA’s latest Drilling Productivity Report from mid-June showed that the number of DUCs fell by 247 between April and May. The report also showed that U.S. shale output from the seven most prolific shale basins is set to grow by 38,000 bpd month over month.
