墨西哥湾漏油事件造成的误工可能会削减近几年近海盆地的石油产量。但是,由于新兴陆上油田的数量增长,正在帮助美国填补这一时期的石油缺口。石油和天然气公司,利用近几年掌握的从页岩及其它致密岩石中提取天然气的技术,从德克萨斯州至北达科他州地区的致密岩石建造中成功地提取到大量石油。在持续攀高的油价的同时,低价页岩气却充实着美国的市场。 False labor caused by the Gulf of Mexico oil spill may cut oil production in offshore basins in recent years. However, the growing number of new onshore oil fields is helping the United States to fill the oil shortfall of this period. Oil and gas companies, using techniques known in recent years to extract natural gas from shale and other tight rocks, have succeeded in extracting large amounts of oil from dense rock formations in Texas to North Dakota. As oil prices continue to rise, low-cost shale gas fills the U.S. market.
