Creating concepts for static and dynamic uncertainty modeling

Important You can use a simulation concept as direct input to a simulation case. This way you propagate the information of the domain models (e.g., porosity model, fluid model) to the simulation case which ensures that models are geologically consistent and model dependencies are retained.

Performing simulation studies with the integrated workflow between JewelSuite and CMOST, is only possible for CMG simulators IMEX, GEM and STARS.

Setting up one or more concepts is the first step to set up uncertainty modeling for static/volumetric calculations , or dynamic simulation . With the functionality of the concept strip you define one or more reservoir descriptions, where each reservoir description represents one concept. More specifically, a concept is a set of interdependent domain models (e.g., a stratigraphic model, structural model, 3D grid, fluid model) representing one conceptual idea of your reservoir model. The concepts you create with the concept strip are required as input to the volumetric study (study > Volumetrics > Volumetrics Study) and simulation study (jewellabs > Simulation Study) workflows, where the actual uncertainty run is set up in more detail.

The domain models contained in your volumetric or simulation concept contain the parametric uncertainties that will be sampled during the uncertainty calculations. You either already have specified these parametric uncertainties when creating the volumetric or simulation concept, or you can specify them when setting up the study. For more on uncertainty calculations in JewelSuite 2026.1 Subsurface Modeling, see Incorporating uncertainty in static or dynamic modeling.

For volumetric uncertainty modeling, you can have multiple concepts in one uncertainty calculation. Combining multiple concepts into one volumetric uncertainty run allows you to incorporate conceptual uncertainty, where each concept has its own, user-defined probability. Uncertainty in dynamic simulation, however, always runs with one single concept and uncertainty comes from the geological uncertainties (e.g., porosity and permeability) assigned to the domain models of the concept.

A set of Concept Tools are available in the strip that allows you investigate the input dependencies of the associated domain models in a volumetric concept, and create an automated JewelScript that models the entire concept modeling workflow from 3D structure to the saturation model.
