DRILLING ThermaSource Drilling engineer and project management company ThermaSource is currently drilling in Klamath Falls, Oregon, on Oregon Institute of Technology’s (OIT) campus. OIT is developing the geothermal resource for electric power generation, which will make the campus the world’s first to have all of its energy needs met using geothermal energy. OIT’s total well depth is between 3,000 and 6,000 feet, depending upon the quality of the resource. ThermaSource is proud to be the drilling contractor at OIT, as it is a great sign of OIT’s commitment to renewable energy, which should inspire similar geothermal/renewable energy projects around the world. www.thermasource.com

Atlas Copco Available in America for the first time is the Atlas Copco Mustang 4-F1, a down-the-hole, track-mounted rig that is compact and equipped with everything needed for drilling geothermal holes. Mustang 4-F1 can reach where others can’t, such as a basement of a high-rise or a fenced-in back yard. It makes its way around landscaping with minimal disturbance. Cuttings are blown directly into a waste container, reducing debris. Mustang 4-F1 has a Tier 3 Deutz diesel engine with low fuel consumption. The quiet-running compressor puts out 350 psi, 700 cfm air, and the lubricating system allows adequate lubrication of the DTH hammer, keeping the risk of soil pollution down. The Mustang can drill down to 490 feet and runs up to 125 rpm with torque of up to 4,200 foot pounds. With a pull length of 12.8 feet, the rotation unit can effortlessly lift the drill string up. www.atlascopco.us 66

Cryostar Cryostar is an international company, part of the Linde group, specialized in cryogenic rotating machinery equipment for industrial gas, natural gas, and biogas liquefaction plant. Based on this experience and on the trend to produce clean energy, Cryostar has recently expanded its activities with the development of its Lo-C (low carbon) products line, and is now offering expertise for CO2 free power generation (pressure-let-down, geothermal, waste heat recovery) with a full range of turbo expanders. Its installed base comprises of over 130 radial inflow turbines and more than 60 MW installed over the world, including 20 machines on a natural gas distribution network. For instance, in Unterhaching geothermal project (Germany), Cryostar has played a role supplying a TG-500 expansion turbine—capable of producing up to 3.7 MW of electricity—adapted to the Kalina-based power plant cycle. In Soultz-sous-Forêts (France), Cryostar also supplied a TG-400 for the Hot Dry Rock
ORC project, capable of producing 2.5 MW electricity. Those turbines were adapted from the existing Cryostar range of turbogenerators. Cryostar also provides geothermal turnkey power plants based on ORC process. www.cryostar.com Fuji Electric Fuji Electric is a manufacturer of highly efficient and reliable steam turbines, generators, and related services for the geothermal industry. www.fujielectric.com
