據管道&天然氣雜志網8月2日報道，大型頁巖油公司先鋒自然資源（Pioneer Natural Resources）首席執行官謝菲爾德（Scott Sheffield）周三援引沙特減產以及美國生產商投資不足表示，由于供不應求，今明兩年油價將在80至100美元/桶區間波動。

他的預期低于其今年早些時候預測的90至100美元區間。7月份油價出現反彈。

計劃于12月卸任的謝菲爾德表示，全球石油庫存將在年底前下降。他預計，沙特可能延長100萬桶/日的減產協議，而美國經濟的軟著陸可能有助于提振整體需求。

由于美國頁巖油生產商削減支出，近幾個月油價疲軟也影響了新油井的鉆井和完井。周三，全球原油交易價格約為每桶83美元，美國原油交易價格約為每桶79.36美元。

先鋒自然資源表示，今年年底的平均鉆機數可能持平，而此前的預測是每年增加1至2臺鉆機。

周三下午股價上漲2.3%至229.74美元，此前一天，先鋒公布了好于預期的季度利潤，并削減了資本支出。

US Shale Firm CEO Predicts $80-$100 a Barrel of Oil Through 2024

Oil prices will range between $80 and $100 a barrel this year and next as demand outpaces supply, Scott Sheffield, chief executive officer of top shale firm Pioneer Natural Resources, said on Wednesday, citing output cuts by Saudi Arabia and underinvestment by U.S. producers.

His outlook is lower than the $90-$100 range he had forecast earlier this year. Oil prices rallied in July has pledged measures to revive its economic growth.

Global oil inventories will fall through year-end, said Sheffield, who plans to step down in December. Saudi Arabia could extend its 1 million barrel-a-day cut and a soft landing for the U.S. economy could help fuel overall demand, he predicted.

Weak oil prices in recent months have also hurt drilling and completion of new oil wells as U.S. shale producers curb spending. The global oil benchmark was trading at about $83 a barrel and U.S. crude about $79.36 a barrel on Wednesday.

Pioneer said it may end the year flat on average rig count, compared with a previous forecast to add 1-2 rigs a year.

Shares were 2.3% higher at $229.74 on Wednesday afternoon, a day after Pioneer reported a better-than-expected quarterly profit and cut capital spending.
