Numerical reservoir simulation is one of the effective tools for complex fluid analysis in the oil industry. This paper analyzed the principle of thermal recovery simulation, and designed and implemented a parallel program of the thermal recovery simulation based on PESTc toolkit. The improved domain decomposition with load-balance control was presented to partition the computation into different processing units efficiently. Compared with the serial program, our implementation can gain 8.16 times speedup using 16 cores over a large-scale reservoir test case.
