Summary: Summary
Naturally fractured reservoirs contain a significant amount of the
world oil reserves. A number of these reservoirs contain several
billion barrels of oil. Accurate and efficient reservoir simulation of
naturally fractured reservoirs is one of the most important,
challenging, and computationally intensive problems in reservoir
engineering. Parallel reservoir simulators developed for naturally
fractured reservoirs can effectively address the computational
problem.
A new accurate parallel simulator for large-scale naturally
fractured reservoirs, capable of modeling fluid flow in both rock
matrix and fractures, has been developed. The simulator is a parallel,
3D, fully implicit, equation-of-state compositional model that solves
very large, sparse linear systems arising from discretization of the
governing partial differential equations. A generalized dual-porosity
model, the multiple-interacting-continua (MINC), has been
implemented in this simulator. The matrix blocks are discretized into
subgrids in both horizontal and vertical directions to offer a more
accurate transient flow description in matrix blocks. We believe this
implementation has led to a unique and powerful reservoir simulator
