Exascale computing to plan future oil and gas production and environmental security

length of scales for a single geoscience computation

The approach illustrated here involves length scales for a single computation shown by the circles, with the full range of scales (nm to km) covered by different overlapping models.

Like a sponge below the surface of the Earth, porous sedimentary rock traps petroleum and natural gas in reservoirs until these resources are pumped through manmade wells and extracted. Increasingly, sophisticated simulators that model the flow of water, oil, and gas are being used to analyze extraction strategies as well as potential environmental impacts of energy production in the United States. Modeling and simulation is also enabling scientists to explore the safe and efficient use of subsurface geology for carbon dioxide sequestration and nuclear waste isolation.

However, scientists need more computing power to model the many length and time scales important to predictions of reservoir resources and long-term integrity—from micron-sized pores in rock, to small fractures, to fluid flow, to mechanical stressors like seismic activity and drilling. At exascale, researchers will be better able to resolve these multiple scales and their impact on each other over long periods of time.
