Acknowledgments First I would like to thank my supervisor, Professor Mary F. Wheeler, for her support and supervision. She has guided my studies and encouraged my work in computational and applied science and engineering. She has not only mentored me academically as a researcher; she has also taught me valuable life lessons. All the work done in this(More)
We have ported a fully implicit EOS (equation-of-state) compositional parallel reservoir simulator to a cluster of PCs. We report on the performance of the cluster, both in terms of scalability and in absolute performance relative to an IBM SP. The simulator scales well through 16 processors, with each run taking less than twice as long as the comparable(More)
The recent development of tight oil reservoirs has led to an increase in oil production in the past several years due to the progress in horizontal drilling and hydraulic fracturing. However, the expected oil recovery factor from these reservoirs is still very low. CO2-based enhanced oil recovery is a suitable solution to improve the recovery. One challenge(More)
Laboratory measurements of saturation-dependent relative permeability are commonly used to construct reservoir models. However, because of sample size and paucity, their reliability to predict real-time production behavior of heterogeneous formations remains questionable. This paper introduces a new method to estimate near-wellbore hydrocarbon-water(More)
Since a large amount of nanopores exist in tight oil reservoirs, fluid transport in nanopores is complex due to large capillary pressure. Recent studies only focus on the effect of nanopore confinement on single-well performance with simple planar fractures in tight oil reservoirs. Its impacts on multi-well performance with complex fracture geometries have(More)
A complex fracture network is generally generated during the hydraulic fracturing treatment in shale gas reservoirs. Numerous efforts have been made to model the flow behavior of such fracture networks. However, it is still challenging to predict the impacts of various gas transport mechanisms on well performance with arbitrary fracture geometry in a(More)
