Coupled prolongation in multi-scale pressure solver for high-contrast heterogeneous reservoir simulation

Efficient multi-scale methods for reservoir simulation require constructing a set of prolongation operators that interpolate solutions from a coarse spatial resolution to a grid resolution. An improved algorithm captures strong contrasts in geological properties better for this objective. Utilizing the new algorithm, operators can obtain better linear and nonlinear convergence rates than previously.
