  • Constructing Geologic Models From Geologic Concepts
    Publication number: 20130246031
    Abstract: Method for constructing a geologic model of a subsurface region. A concept region and a geologic concept is selected (300). A design region is created corresponding to the concept region (310). A conceptual model is generated compatible to data in the design legion (320). The conceptual model is mapped from the design legion concept region (330). The conceptual interfaces and region properties may be adjusted to match data in the concept region (340).
