越来越多的人声称，世界正在进入“天然气的黄金时代”，预计非常规资源的开采将改变全球天然气市场。但这些资源的未来开发受到多种不确定因素的影响，特别是在实物资源的规模和可回收性方面。本文评估了区域和全球非常规天然气资源规模的现有证据。特别是页岩气，它首先探讨了资源估计中使用的各种术语和定义的含义和适当解释，然后总结和比较迄今为止产生的不同区域和全球估计。它显示了这些估计数如何随着时间的推移而增加，并强调了它们的可变性、广泛的不确定性以及大多数研究对这种不确定性的处理不足。该文件还讨论了煤层气和致密气，并确定了对每个地区来说似乎最可靠的估计数。本文的结论是，非常规天然气可能占天然气剩余技术可采资源的40%，但不确定性极高，经济可采资源可能会大大减少。(C)2013爱思唯尔有限公司保留所有权利。
It is increasingly claimed that the world is entering a 'golden age of gas', with the exploitation of unconventional resources expected to transform gas markets around the world. But the future development of these resources is subject to multiple uncertainties, particularly with regard to the size and recoverability of the physical resource. This paper assesses the currently available evidence on the size of unconventional gas resources at both the regional and global level. Focussing in particular on shale gas, it first explores the meaning and appropriate interpretation of the various terms and definitions used in resource estimation and then summarises and compares the different regional and global estimates that have been produced to date. It shows how these estimates have increased over time and highlights their variability, the wide range of uncertainty and the inadequate treatment of this uncertainty by most studies. The paper also addresses coal bed methane and tight gas and identifies those estimates that appear to be most robust for each region. The paper concludes that unconventional gas could represent 40% of the remaining technically recoverable resource of natural gas, but the level of uncertainty is extremely high and the economically recoverable resource could be substantially smaller.
