最小勘探工作量与最小义务工作量辨析

The Relationships and Differences of Two Key Concepts in International Exploration: Minimum Exploration Workload and Exploration Obligation

最小勘探工作量与最小义务工作量是跨国油气勘探的两个关键概念。最小勘探工作量决定了勘探运营过程中的投资决策优化,而最小义务工作量作为勘探合同或许可证协议的关键参数,决定了勘探区块的基本沉没成本。理论上,任意勘探区块都存在可测算的最小勘探工作量。剩余风险前后的最小勘探工作量直接限定了最小义务工作量的技术上限和下限。作为合同杠杆的最小义务工作量除了遵循技术判定准则以外,还必须服从风险门槛准则、战略契合性准则和竞争结盟准则。基于这四项判定准则的层次分析方法,可以得到最小义务工作量的优化解。对最小勘探工作量与最小义务工作量的分析,不仅辨析了这两个概念之间的异同,同时也显示了理论和技术研究在理性决策中的作用。

Minimum exploration workload (MEW) and Exploration obligation (EO) are two key concepts in international exploration ventures. MEW requires the investment optimization of the exploration sector. EO encourages minimal expenditures for exploration contract agreements. It has been shown theoretically, that there is a MEW in any exploration sector. Technically, the remaining high and low risk MEW could be used as the lower and upper limits of EO. However, EO, the contract arm, must still meet three requirements other than the technical guidelines. These are risk limitation, and conformity with the oil company's strategy and competition goals. Based on the three rules, EO can be optimized by using the AHP method. The analysis of MEW and EO stated not only the relationships and differences, but also showed that technical research plays an important role in rational decision-making.
