Indeed , reserves of gas already stand at 87 percent of oil reserves in terms of energy content 的确如此，就能源存量而言，天然气的蕴藏量已经达到石油的87 %了。
The arab nations and their allies in the middle east control 55 percent of the world ' s proved oil reserves 阿拉伯各国以及他们的中东盟国拥有世界石油已知蕴藏量的55 。
Campbell and others assert that these estimates are far too high because countries exaggerate the amount of petroleum still in the ground 坎贝尔与其他学者认为，这些估计数字都偏高太多，因为有许多国家过度夸大剩馀的原油蕴藏量。
Supported the establishment of a licensing permit system and urged afcd to institute a quota system based on actual assessments of stocks 支持成立发牌许可证系统及促请渔农自然护理署执行按实际渔业资源蕴藏量而发出的限额分配制度。
Using the endowment , discoveries , and consumption data , model the depletion or degradation of the commodity over a long horizon using resource modeling principles 利用资源模型化原则，使用蕴藏量，已发现储量，每年消费额的数据，建立一个世界范围的日常消耗或退化的模型。
Although the resource base of other fossil fuels such as oil sands , heavy oil and oil shale is very large , they are likely to supply only small amounts of energy before the year2000 虽然其他的矿物燃料如油砂、重油和油页岩的蕴藏量很大，但在2000年前，似乎只能供应能量中的一小部分。
Natural gas reserves are large enough to meet projected demand , provided the incentive are sufficient to encourage the development of extensive and costly intercontinental gas transportation systems 天然气有很大的蕴藏量，足够满足有计划的需求，假如能有足够的利益刺激开发昂贵的洲际天然气运输通道。
Companies also have a stake in exaggeration , as in the recent case of the royal / dutch shell group , which admitted that its “ proven reserves ” were 20 percent less than originally stated 石油公司本身也参与这样的夸大行为，最近的例子是荷兰皇家壳牌石油集团承认其确定蕴藏量比当初宣称的数字少20 % 。
Unlike fossil fuels such as coal and oil , renewable energy will never run out . it is abundant in the environment , and can come from the sun , wind , running water , waves , and biomass 可再生能源与化石燃料（例如煤及石油）不同之处，在于前者可让我们用之不竭，而且在周围环境中蕴藏量极多，可来自太阳、风、流水、海浪及生物质能等。
Pinnau believes that in the future , high - performance membranes could separate unwanted hydrocarbons from methane ? a feat that could make the exploitation of vast untapped natural gas deposits considerably more economical 皮诺相信，未来的高效能滤膜可以滤除甲烷中无用的碳氢化合物，使得让蕴藏量丰富的天然气，在开采与储存上都更符合经济效益。
