One of the many obstacles for hopeful settlers is the need for power and heat on these barren landscapes. Some geologists and other scientists theorize that geothermal energy may be the answer.
Geothermal Resource Group (GRG) is a geothermal resource and engineering consulting company that has provided consulting engineering and on-site management services in over 16 countries and at over 95 geothermal development projects worldwide. They have been a partner in the FORGE Utah project since the beginning, providing technical and design advice, and planning and supervision in the drilling of all deep wells, including 58-32, 68-32 and 78-32. They are currently working on the design of the first deep deviated well which will commence later this year.
GRG plays a critical role in the management, organization and running of a range of pre- and post-drilling and stimulation activities to ensure that project managers, contractors, and researchers are well informed of scheduling and onsite activities. A key goal is to ensure that everyone involved is fully briefed on the operations so that all tasks are executed to the highest professional and technical standard an in a timely manner that keep the project on schedule and within budget.
In Phase 3, GRG is working within the drilling team to specify the materials needed for the planned deep, highly deviated, injection well that represents one of the pillars of the Utah FORGE research facility. This involves many considerations that are not typical to conventional geothermal wells. In addition, specifications are being prepared for the drilling of additional seismic monitoring holes, as are plans for supervision of field activities later this year.
GRG’s involvement with Utah FORGE is led by Principal Drilling Engineer Bill Rickard, Senior Engineer Ernesto Rivas, and Geologist Mary Mann. GRG brings with them many decades of cutting edge expertise hard granite drilling technology, and they were instrumental in the drilling and completion of deep wells at Newberry and Raft River. GRG is excited to be a part of the Utah FORGE project and looks forward to ensuring continued drilling successes.
