中国石化新闻网讯 据管道&天然气杂志网8月2日报道，大型页岩油公司先锋自然资源（Pioneer Natural Resources）首席执行官谢菲尔德（Scott Sheffield）周三援引沙特减产以及美国生产商投资不足表示，由于供不应求，今明两年油价将在80至100美元/桶区间波动。
他的预期低于其今年早些时候预测的90至100美元区间。7月份油价出现反弹。
计划于12月卸任的谢菲尔德表示，全球石油库存将在年底前下降。他预计，沙特可能延长100万桶/日的减产协议，而美国经济的软着陆可能有助于提振整体需求。
由于美国页岩油生产商削减支出，近几个月油价疲软也影响了新油井的钻井和完井。周三，全球原油交易价格约为每桶83美元，美国原油交易价格约为每桶79.36美元。
先锋自然资源表示，今年年底的平均钻机数可能持平，而此前的预测是每年增加1至2台钻机。
周三下午股价上涨2.3%至229.74美元，此前一天，先锋公布了好于预期的季度利润，并削减了资本支出。

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.
