[54] PARALLEL SOLUTION OR FULLY-COUPLED FULLY-IMPLICIT WELLBORE MODELING IN RESERVOIR SIMULATION
[57] Abstract: Computer processing time and results are improved in fully-coupled fully-implicit well-reservoir simulation system using Jacobian matrix methodology. Approximate inverse preconditioners are provided which treat a well influence matrix at comparable accuracy and robustness to those for the grid-to-grid flow terms of system matrix. The methodology is highly parallelizable and the data processing can be performed faster, as fewer solver iterations are required to converge to the same acceptable tolerances.
