Petrel play and arospect assessment is a map-based assessment workflow with a flexible setup that enables users to assess conventional and unconventional opportunities. Your company’s risk model from GeoX exploration risk, resource, and value assessment software’s database can be imported and used with different volume estimation methods. Assessment units can be defined using geopolygons, manually, or from the Play Chance Mapping package in Petrel subsurface software. The generated results then define the geological chance of success and resource potential for the units. The results can be saved into the corporate exploration portfolio in the GeoX software database.
