Scalable flow simulation is an extremely useful reservoir engineering capability with applications to model calibration, uncertainty estimation, field optimization, and reservoir management. Recent examples have emphasized the formulation of simulation problems as pore volume/transmissibility networks to develop fast physics-based proxy models. In the study described in the complete paper, the authors develop an adaptive grid-coarsening approach based on constraints that honor reservoir structure and stratigraphy, preserve fluid volumes and contacts, and retain resolution near wells. The technique may be implemented within commercial reservoir simulators.
Problem Statement
The commercial simulator used includes several powerful features within its grid-coarsening implementation.
