Natural Gas Proved Reserves

This dataset contains information about world's natural gas reserves from 1980. Data from BP. Follow datasource.kapsarc.org for timely data to advance energy economics research. Notes:^ Less than 0.05. w Less than 0.05%. n/a not available.Total proved reserves of natural gas - Generally taken to be those quantities that geological and engineering information indicates with reasonable certainty can be recovered in the future from known reservoirs under existing economic and operating conditions. The data series for natural gas does not necessarily meet the definitions, guidelines and practices used for determining proved reserves at company level, for instance as published by the US Securities and Exchange Commission, nor does it necessarily represent BP’s view of proved reserves by country. Reserves-to-production (R/P) ratio - If the reserves remaining at the end of any year are divided by the production in that year, the result is the length of time that those remaining reserves would last if production were to continue at that rate. Source of data - The estimates in this table have been compiled using a combination of primary official sources and third-party data from Cedigaz and the OPEC Secretariat. Annual changes and share of total are calculated.

本数据集收录了自1980年以来全球天然气储备的相关信息。数据来源于BP公司。可通过访问datasource.kapsarc.org获取最新数据，以推进能源经济学研究。备注：数值小于0.05。w数值小于0.05%。n/a表示不可用。总探明天然气储备——通常指那些根据地质和工程信息，在现有经济和运营条件下，具有合理把握从已知储层中在未来可开采的量。天然气数据系列并不必然符合公司层面确定探明储备的定义、指南和实践，例如美国证券交易委员会发布的，也不必然代表BP对各国探明储备的看法。储备与产量（R/P）比——若将年末剩余的储备量除以当年的产量，所得结果即为在维持当前产量率的情况下，剩余储备可维持的时间长度。数据来源——本表中的估计值是通过结合初级官方来源以及Cedigaz和OPEC秘书处提供的第三方数据进行编制的。年度变化及总份额计算。
