简介：世界介绍需求因为油和气体为超过60%全球油和煤气的供应仍然在一个快速的生长时期，和传统的油和煤气的资源报道。美洲是第二最大的生产和液体的消费中心造成的世界，并且也是世界最大的天然气制片人。在2016，美洲有853亿大量证明的油储备和证明天然气储备的18.7万亿m3，它说明35.4%世界和10.0%分别地总计储备。它生产了油的1267.1山和天然气的11254亿m3，它分别地说明28.9%世界和31.7%总数生产。原油和天然气储备主要在美国，加拿大和委内瑞拉被散布。美国是在页岩气体探索和开发的最早、很成功的国家，并且它的页岩气体在南部、中央、东方的美国被集中，包括Marcellcus页岩，Barnett页岩，EagleFord页岩，Bakken页岩，Fayettevis页岩，Haynsvill页岩，Woodford页岩和Monterey/Santos页岩。在美洲的潜在的油和煤气的资源主要在西方的加拿大沉积的盆在Williston盆，主导的stratigraphic陷井和很少结构的陷井在北方斜坡盆，古生代的Madsion组白云石和石灰石的中间上面的侏罗记斜坡免职在背斜和stratigraphic陷井被集中，始新世structural-stratigraphic烃联合，结构不顺从的陷井和结构的烃联合，和上面的Miocen另外，地震subsalt成像技术的突破使subsalt成为东方Barzil的深海的海区域重要的油和煤气的潜在的区域。
