A Variable-Switching Method for Mass-Variable-Based Reservoir Simulators
A Variable-Switching Method for Mass-Variable-Based Reservoir Simulators is a scholarly work, published in 2018 in ''SPE Journal''. The main subjects of the publication include dependent and independent variables, finite element method, block, computer science, enhanced oil recovery, design matrix, mathematical optimization, Reservoir simulation, process, variable, nonlinear system, applied mathematics, Jacobian matrix, component, and algorithm. Results indicate that in some models the total number of NR iterations, linear-solver (LS) iterations, and timestep-size cuts (caused by the nonconvergence of the NR procedure, also known as backups) are reduced when using natural variables instead of mass variables.
