Constructing and refining complex reservoir models are challenging and time-consuming tasks that entail a high degree of uncertainty. Conventional modeling work flows have remained essentially unchanged for the past decade. Such work flows are poorly suited to rapid prototyping of a range of reservoir-model concepts, well trajectories, and development options and to testing of how these might affect reservoir behavior. A new reservoir-modeling and -simulation approach, termed rapid reservoir modeling (RRM), allows such prototyping and complements existing work flows.
Introduction
Hydrocarbon reservoirs typically contain an array of complex geologic heterogeneities that are at or below the resolution of seismic data, so their geometry and spatial distribution are uncertain.
