美國(guó)壓裂沙泵入量降至2017年以來(lái)最低水平

據(jù)美國(guó)彭博新聞社休斯敦報(bào)道，由于美國(guó)石油勘探公司調(diào)整以適應(yīng)石油需求和價(jià)格下降，壓裂工人3年來(lái)首次正在減少向頁(yè)巖井中泵入砂子。

根據(jù)科拉斯資源公司公布的統(tǒng)計(jì)數(shù)據(jù)，美國(guó)頁(yè)巖勘探公司在本季度期間平均每天向頁(yè)巖井泵入大約290萬(wàn)磅的沙子，沙子泵入量自2017年第4季度以來(lái)首次減少增加。泵入每口頁(yè)巖井的沙子數(shù)量是壓裂效率的一個(gè)關(guān)鍵測(cè)量，這是因?yàn)楸萌敫嗟纳匙油ǔＲ馕吨嗟膸r石裂縫允許原油流出。

科拉斯能源公司的創(chuàng)始人丹尼爾?克魯斯在周四（9月10日）的一份報(bào)告中寫(xiě)道：“本季度美國(guó)勘探與生產(chǎn)公司投入的壓裂作業(yè)沒(méi)有得到同樣的回報(bào)。如果壓裂效率繼續(xù)下降，它將給美國(guó)頁(yè)氣生產(chǎn)帶來(lái)更大的壓力。”

由于疫情大流行削弱了全球?qū)κ脱苌a(chǎn)品的需求，壓裂工人和其他石油行業(yè)雇傭的工人在這次歷史性的原油崩盤(pán)中遭受了最嚴(yán)重的打擊。全球服務(wù)巨頭斯倫貝謝公司和哈里伯頓公司正將注意力轉(zhuǎn)向北美以外的地區(qū)，未來(lái)國(guó)際銷(xiāo)售將占它們業(yè)務(wù)的更多份額。

科拉斯資源公司稱(chēng)，在美國(guó)壓裂作業(yè)隊(duì)伍的數(shù)量在5月中旬降到了100支低谷以后，已有40支壓裂作業(yè)隊(duì)伍重返工作，其中大部分壓裂作業(yè)隊(duì)伍重返位于西德克薩斯和新墨西哥州的二疊系盆地。

Frac pumping volumes lowest since 2017 as shale slowdown continues

Fracers are blasting less sand into shale wells for the first time in almost three years as oil explorers adjust to lower oil demand and prices amid the coronavirus pandemic.

Shale explorers are pumping an average of roughly 2.9 million pounds of sand a day during the current quarter, marking the first time since the final three months of 2017 that growth has subsided, according to Coras Research LLC. Sand per well is a key measurement of frac efficiency because more sand typically means more of the rock fissures that allow crude to flow.

“E&Ps are not getting the same bang for their frac buck this quarter,” Daniel Cruise, founder of Coras, wrote in a report on Thursday. If frac efficiency continues to decline, it “would put more pressure on U.S. shale production going forward.”

Fracers and other hired hands of the oil patch have been among the most beaten up during the historic crude crash as the global pandemic saps demand for oil-derived products. Global service giants Schlumberger and Halliburton Co. are turning their attention outside of North America, with expectations for international sales to make up more of their business going forward.

After the number of active U.S. frac crews bottomed out at 100 in mid-May, 40 crews have been put back to work, mostly in the Permian Basin of West Texas and New Mexico, according to Coras.
