探明储量
探明储量(英语:proven reserves)被定义为“根据现有地质和工程数据的分析,利用现有设备和现有操作条件。以合理的确定性估计,从已知的油藏中开采的储量” [1]. 如果有至少 90% 的储量可以通过有经济效益方式进行开采,则该储量被定为探明储量。因此探明储量和运营条件有关, 包括价格、监管和合同条件等。如果一个储量的资源可以使用当前的技术进行回收,但在经济上没有利润,那么它被定认为“技术上可采储量” [2]。可采储量低于 90% 但超过 50% 被视为“概略储量”(英语:probable reserves),低于 50% 为“可能储量”(英语:possible reserves) [3]。
