Administration

The Utah Geological Survey seeks to assist the public and professionals in finding information necessary to make informed decisions about geology. Our administration staff are the main contact to the different programs and qualified personnel in the UGS. They are necessary in interacting with the public, coordinating events, and making the UGS run smoothly behind the scenes.

Administration Staff

UGS Director | State Geologist

Bill Keach

Phone: (801) 537-3301
Email: billkeach@utah.gov

Bill is a scientist, educator, and expert in technology with over 30 years of experience in industry, academia, and regulatory state government. After earning a B.S. degree in Geology from Brigham Young University and an M.S. degree in Geophysics from Cornell, Bill spent over five years in offshore hydrocarbon exploration in the Gulf of Mexico and with SOHIO/BP in California. He then joined Landmark Graphics (now Halliburton) where he spent 17 years traveling the world developing 3D visualization technology and adoption. He returned to Utah in 2006 taking roles at both the Energy and Geoscience Institute at the University of Utah and Brigham Young University doing research and teaching courses on seismic interpretation and reservoir modeling. One of his favorite roles in academia has been the opportunity to develop and lead field courses taking students and professionals from around the world throughout Utah to see and learn its many wonders. In 2017 he accepted a role with California’s Division of Oil, Gas, and Geothermal Resources to evaluate reservoirs and bring technology into the division. The latter goal was recently realized with the introduction (first ever) of computer interpretation tools. Another goal was bringing in UAS (drone) technology and developing protocols for regulatory inspections. While in California he has continued his adjunct appointments with the University of Utah and Brigham Young University to satisfy his passion for teaching.
