|Ian J Duncan|
Expertise in geomechanic and geochemistry applied to: risks associated with CO2 sequestration; hydraulic fracturing for shale gas production; environmental impact of hydraulic fracturing; and the water-energy nexus. Current research focuses on the scientific, environmental and public policy aspects of unconventional natural gas production, the water-energy nexus, and carbon capture and storage. He has a particular interest in risk analysis, decision making, and legal/regulatory issues related to fracing, CO2 sequestration, CO2-EOR, and energy production.

Dr. Helper is a field geologist, a generalist whose interests span igneous and metamorphic petrology, structural geology, tectonics, mineralogy and planetary field geology. His current research explores geochemical and isotopic similarities of Proterozoic and Archean crust in East Antarctica and the southwestern U.S., the Precambrian geology of Texas, and the origin of epidote blueschists in the Klamath Mountains of northern California. Recent senior honors theses under his supervision have examined the mineralogy of Texas ...

Are rocks elastic? Not really... especially when saturated with multi-phase fluids. Did you know that a seismic wave is able of mobilizing the liquid saturating rocks and that such a process reduces the seismic wave strength? Yes, this phenomenon, called Wave-Induced-Fluid-Flow could be used to improve subsurface imaging. How? The absorption of elastic energy varies with frequency, this means that certain frequencies are attenuated and other maybe not. Why is this important? Well, adding information ...
