Abstract: 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.

Abstract: A hierarchical conditioning methodology for building and conditioning a geological model is disclosed. In particular, the hierarchical conditioning may include separate levels of conditioning of template instances using larger-scale data (such as conditioning using large-scale data and conditioning using medium-scale data) and using smaller-scale data (such as fine-scale data). Further, one or more templates, to be instantiated to generate the geological bodies in the model, may be selected from currently available templates and/or machine-learned templates. For example, the templates may be generated using unsupervised or supervised learning to re-parameterize the functional form parameters, or may be generated using statistical generative modeling.
