  "definition": "1. A mappable volume of rock within the total petroleum system that encompasses fields (discovered and undiscovered) which share similar geologic traits and socio-economic factors. The fields within an assessment unit should constitute a sufficiently homogeneous population that the chosen methodology of resource assessment is applicable.\n\n2. A mappable volume of rock within a total petroleum system that encompasses accumulations (discovered and undiscovered) that share similar geologic traits and socio-economic factors. Accumulations within an assessment unit should constitute a sufficiently homogeneous population such that the chosen methodology of resource assessment is applicable. A total petroleum system might equate to a single assessment unit. If necessary, a total petroleum system can be subdivided into two or more assessment units in order that each unit is sufficiently homogeneous to assess individually. An assessment unit may be identified as conventional, if it contains conventional accumulations, or as continuous, if it contains continuous accumulations.\n\n3. An assessment unit is a volume of rock within the Total Petroleum System that encompasses fields, discovered and undiscovered, sufficiently homogeneous in terms of geology, exploration strategy and risk characteristics to constitute a single population of field characteristics with respect to criteria used for resource assessment.",
