Sandia and Atlas-Copco Secoroc Advance to Phase 2 in Their Geothermal Energy Project

In 2012, the partnership between Sandia and Atlas-Copco Secoroc was awarded a $3.4M DOE grant to develop a down-the-hole (DTH) hammer capable of low-cost, high-production drilling in the extreme heat of deep geothermal wells. The overall DOE goal is to increase the feasibility of geothermal energy production by lowering the cost and financial risk associated […]

Sandia-Developed Alloy Has Potential for Electronics in Wells

A few years ago, researchers asked Sandia’s geothermal group to develop electronics to monitor well conditions in field operations—withstanding high temperatures and pressures, excessive vibrations, and other extreme environments. Most brazing processes occur at a peak temperature above about 700° C, while most soldering occurs below 350° C, leaving high-temperature electronics few filler materials from which to […]
