Center for Subsurface Imaging and
Fluid Modeling (CSIM) Consortium
• Goal: Develop innovative and integration of computational
•
methods for seismic imaging and subsurface fluid flow
modeling. Examples include 3D waveform inversion, 3D RTM,
TI modeling, reservoir fluid simulator.
Advantages More than $2,000,000 in KAUST research
funds, tightly coupled visualization+supercomputer resources
+ reservoir fluid modeling+ seismic imaging
Computers: IBM Blue Gene 225 Tflop, Intel+GPU Clusters
:
•
GPU+IBM experts
• Benefits: Yearly Houston meeting, annual reports, access to
student interns, expert in fluid flow modeling, seismic, and
eventually EM imaging
• Collaborations: UT Austin (Stoffa+TTI), PSU+UU (GPU)
Research Goals
G.T. Schuster (Columbia Univ., 1984)
Seismic Interferometry: VSP, SSP, OBS
Multisource+Preconditioned RTM+MVA+Inversion+Modeling:
TTI 3D RTM, GPU: Stoffa+CSIM, UUtah K. Johnson SCI, PSU, KAUST

Research Goals
Shuyu Sun (UT Austin, 2005)
Modeling of multiphase flow in porous media
(new approaches for fractures, diffusion, capillarity …)
Advanced finite element methods
(dynamic mesh adaption, multiscale resolution,
element-wise conservation, efficient linear solvers, …)
Computational thermodynamics of reservoir fluid
