EGS Participant Bio: Trenton Cladouhos

April 16, 2012

Trenton Cladouhos is the Senior Vice President of Research and Development at AltaRock Energy and manages most of the geologic and geophysical aspects of the Newberry Volcano EGS Demonstration.

What exactly does his job entail?

Trenton regularly works with experts in the field to collect and interpret the data we use to design and monitor the stimulation. He was the primary author on the Induced Seismicity Mitigation Plan, and he is quite involved with sharing information with the geothermal community and with the public.

“In many ways, from permitting to equipment selection to modeling, we are writing the how-to book on EGS,” said Trenton. “Sharing that knowledge with the geothermal community and the public is very rewarding, because almost everyone wants us to succeed, making it possible to greatly expand geothermal energy and make us less reliant on fossil fuels.”

What’s On Trenton’s Resume?

Trenton holds a B.Sc. degree in Geology from Stanford University and a Ph.D. in Geological Sciences from Cornell University. He’s worked on projects around the world, ranging form mining to enhanced oil and gas recovery to nuclear waste repository design and now to geothermal energy.

Fractured Rock + Biking To Work

Trenton describes his specialty as “mechanics and fluid flow in fractured and faulted rock through field work and modeling.”

So in 2008 when he was looking to get back into geology, he “couldn’t believe my luck that AltaRock, a Seattle-based geothermal company just a 10-minute bike ride from my house, was looking for a geologist who understood mechanics and fluid flow in fractured rocks.”

AltaRock has been quite pleased as well.

    Who is doing the drilling, and what depths are they looking penatration ? Thanks Jim Winney

      Thanks for your question.
      The five new boreholes for seismic monitoring will be drilled by water well rigs (Foremost DR24s) run by Tacoma Pump and Drilling out of western Washington. These holes will be 700-1000 feet deep, about 100 feet below the top of the water table, which is very deep on the flanks of Newberry. Borehole seismometers will be installed at the bottom of the holes.
      The geothermal production wells will be far deeper, probably 8000-12000 feet. The decision about whether to drill those wells and who will drill them will need to wait until have stimulated the existing injection well this fall.
