A Look Inside the Earth

Imaging subsurface geologies is critical in a variety of tasks: locating new sources of energy and water to power our everyday lives, protecting and safeguarding our environment by preventing subsurface contamination, and mitigating global warming through safe sequestration of carbon dioxide (CO2). Generally it is imaging of fluids present in geological formations that is of interest. Such fluids would include hydrocarbons, brines, steam, and magma present in high temperature geothermal systems, potable ground water, contamination plumes, and dissolved CO2 sequestered in porous rock formations.
In a recent article in XRDS (an Association for Computing Machinery publication), ESD’s Geophysics Department Head Greg Newman discusses the challenges inherent in looking inside the Earth’s subsurface, particularly the role that large-scale parallel computational resources can play in accurate, difference-making subsurface imaging.
