Super basins are sedimentary basins with more than 5 billion BOE cumulative production and at least 5 billion BOE remaining recoverable resources. Super basins are characterized by two or more source rocks, stacked reservoirs, mature infrastructure, established service sectors, large amounts of data, and access to markets. Super basins commonly have multiple operators that form a community whose competitive atmosphere helps drive efficiency and performance. In an effort to identify sources for future oil and gas supplies, studies of the geology, hydrocarbon richness, and above-ground factors for 400 global basins led to the super basin concept. Super basins have continuous organic-rich mud rocks and other tight reservoirs that heretofore were not considered commercial targets. Based on analogy with proven resource plays in North American super basins, it is now possible to unlock substantial hydrocarbon potential in these tight rocks by employing horizontal drilling and multistage fracturing technologies.Super basins exist both onshore and offshore. The largest super basins are onshore, dominantly in forelands and passive margins, and have both conventional and tight rock potential. This paper focuses on the top 25 onshore super basins that are estimated to have 859 billion BOE of incremental technically recoverable resources. Offshore basins do not have the massive tight rock potential as onshore basins because of higher infrastructure costs. The archetype for the onshore super basin is the Permian Basin (west Texas) with 37 billion BOE produced and 60 billion bbl of oil and 300 TCF gas remaining.With huge resources, super basins can serve as supply disrupters and act as a regulator for the global price of crude oil and natural gas. Super basin concepts have caused geoscientists to think differently about petroleum basins. Super basins should be viewed as ecosystems that have below- and above-ground questions and technology and market considerations that must be resolved to assure commercial success.

超级盆地—石油和天然气供应的新范例

超级盆地是沉积盆地,其累计产量超过50亿桶油当量,剩余可采资源至少有50亿桶油当量。超级盆地的特征是两个或多个烃源岩,堆积的储层,成熟的基础设施,已建立的服务部门,大量的数据以及进入市场的机会。超级盆地通常有多个运营商组成一个社区,其竞争氛围有助于提高效率和绩效。为了确定未来的石油和天然气供应来源,对400个全球盆地的地质,油气富集度和地上因素进行了研究,从而形成了超级盆地概念。超级盆地具有连续的富含有机物的泥岩和其他致密的储层,而这些储层迄今尚未被视为商业目标。基于在北美超级盆地中已探明资源储量的类比,现在可以通过采用水平钻井和多阶段压裂技术来释放这些致密岩石中的大量碳氢化合物潜力。超级盆地存在于陆上和海上。最大的超级盆地在陆上,主要分布在前陆和被动边缘,具有常规和致密的岩石潜力。本文着重于排名前25位的陆上超级盆地,这些盆地估计有8590亿桶油当量的增量技术可采资源。由于基础设施成本较高,近海盆地没有像陆上盆地那样巨大的致密岩石潜力。陆上超级盆地的原型是二叠纪盆地(德克萨斯州西部),生产了370亿桶油当量,剩余600亿桶石油和300吨TCF天然气。超级盆地可以充当供应中断者,并充当全球原油和天然气价格的监管者。超级盆地概念使地球学家对石油盆地的看法有所不同。超级盆地应被视为具有地下和地面问题以及必须解决的技术和市场考虑因素的生态系统,以确保商业成功。
