The goal of reservoir modeling is to
generate numerical representations of reservoir geology that honors both hard
(well and core) and soft (seismic and production) data collected from the
reservoir. Traditional numerical reservoir modeling approaches are limited in
their ability to include interpretive information and their resulting models
often lack geologic realism. A shifting modeling paradigm from 2-point
variogram-based statistical methods toward training image-based methods is
empowering modelers to integrate descriptive geological interpretations with
numeric field data. Advances in pattern-based modeling (Strebelle,2000; Arpat, 2005; Zhang, 2006) have made it possible to
mimic the geometry of complex geologic structures while conditioning to the
diverse suite of data typically encountered in hydrocarbon reservoirs,
presenting a greater opportunity to include qualitative geological
interpretations into the numerical reservoir model.
