Petroleum Reserves and Resources: Frameworks, Uncertainty & Economic Decision-Making (PBM53)

    Description

    Assessment of reserves and resources underpins economic decision-making in the upstream sector. Reserves are a subset of resources: they are volumes that are both technically recoverable and commercially viable. Estimation depends on production technology and economic conditions, not just subsurface characteristics.
    This course equips professionals to classify subsurface volumes using frameworks like PRMS and SEC, apply probabilistic methods, and assess both technical feasibility and commerciality. We focus on quantifying uncertainty, distinguishing between volume and value, and integrating reserves reporting into strategic investment decisions.

    Course Level: Skill
    Duration: 5 days
    Instructor: Babak Jafarizadeh
