摘要： Geologic modeling methods and systems are provided with a novel log segmentation approach and an improved conditioning technique for fitting geobody templates to associated well segments in multiple wells. One illustrative geologic modeling method embodiment includes: deriving a sequence of well segments from each logged well in a region of interest; associating well segments from different wells to form sets of associated well segments; populating a region of interest with geobodies by fitting a parameterized geobody template to each set of associated well segments; using the geobodies to specify a volumetric distribution of formation properties throughout the region of interest; and providing the volumetric distribution as a geologic model suitable for evaluating one or more well placement and production strategies.

摘要： A method and system are described for creating a subsurface model. In this method, a framework is obtained that includes various objects associated with a subsurface region. A background mesh is generated to enclose the framework and then cell splitting is performed to modify the background mesh into a watertight model. The watertight model may be assigned properties and utilized in simulations to assist in performing hydrocarbon operations.
