  Abstract This presentation introduced visual protection in VR. It showed that most users preferred the alteration of a region of cells as opposed boxes. Blur was considered less useful, too much distortion of all detail. Illustrative method was thought have great potential but may need to adjust the illustrative rendering technique. It was needed […]

  Abstract In this presentation, new integrated method to characterize HF-induced seismicity was given.  Four major faults were identified by ant-tracking technique in good agreement with focal mechanism results of events clusters. The rock geomechanics and stress field with fluid flow inside fractures were coupled. Three types of trigger mechanisms for HF-induced seismicity were identified. […]

  Abstract This presentation shows that  a parallel simulator has been developed. Its results matched commercial simulator, CMG. The simulator can model giant reservoir models. The simulator has good scalability and performance improvement.

  Abstract This work shows that for large-scale highly heterogeneous reservoir simulation, CPR can be accelerated 6 times faster on average on Tesla C2050 GPU than on Intel Xeon X5570 CPU.  CPR has shorter running time than ILU0 on GPU. CPR has better convergence than ILU0 on GPU.
