Abstract:

As one of the main energy resources, oil plays an important role in transportation, industrial production and daily life. A large number of technologies have been developed to maximize oil production. For instance, polymer flooding has been widely applied in China. The simulation of polymer flooding in naturally fractured reservoirs is vital to sustainable oil production and extension of the life of oil fields. We develop a scalable parallel reservoir simulator to simulate real oil production in naturally fractured reservoirs using polymer flooding technology, with which reservoir engineers can study production technologies using powerful parallel computers and optimize oil production. Comparison with commercial software shows that our simulator is correct and efficient. Besides, numerical experiments demonstrate that our simulator is scalable and can calculate large-scale reservoir models with hundreds of millions of grid blocks by using thousands of CPU cores.
