美国石油工程师学会(SPE)和世界石油大会(WPC)不久前对油气储量作出新定义。储量(Reserve)被定义为“预计从给定日期以后从已知储层中可商业采出的那部分石油的数量”。储量的所有估计值均包含不同程度的不确定性。显然,不确定性程度取决于评估时地质和工程数据的质量,以及对这些数据的解释。为明确这种不确定的程度,SPE 和 WPC 保留了储量定义的两个 The American Petroleum Institute (SPE) and the World Petroleum Congress (WPC) recently made a new definition of oil and gas reserves. Reserve is defined as “the amount of oil that is expected to be commercially produced from a known reservoir after a given date.” All estimates of reserves contain varying degrees of uncertainty. Obviously, the degree of uncertainty depends on the quality of the geological and engineering data at the time of the assessment, as well as the interpretation of these data. To clarify this level of uncertainty, both SPE and WPC retained two definitions of reserves
