John McLennan: Utah FORGE: Hydraulic Fracturing for an Enhanced Geothermal System (EGS)

Prof. John McLennan of U. of Utah presents "Utah FORGE: Hydraulic Fracturing for an Enhanced Geothermal System (EGS)" at the MIT Earth Resources Laboratory on 11/03/2021. "In 2014, the U.S. DOE initiated a multi-year initiative, known as the Frontier Observatory for Research in Geothermal Energy (FORGE) to develop technologies for characterizing, creating, and sustaining an EGS. Since its inception, multiple vertical monitoring wells -for geophone emplacement – have been drilled, along with a 65° lateral. This inclined well, 16A(78)-32, drilled in late 2020, will be stimulated in three stages near its toe. A second inclined well will be drilled in 2022 to penetrate microseismic clouds from these treatments. These three stages will test open hole versus cased-perforated completions, low viscosity versus temperature tolerant higher viscosity fluids, temperature tolerant isolation and perforation technologies, and an assessment of the role of natural fractures during stimulation in crystalline formations. The FORGE project is updated – status, plans, and opportunities. Areas of technology transfer from oil and gas activities – and upcoming challenges - are indicated. These include drilling, cementing, isolation, treatment strategies, conductivity and connectivity development, and challenges related to conformance and immunity to undesirable seismicity. Modeling, simulation, and methods for evaluation of in situ properties are also highlighted briefly." Since October 2009, Professor John McLennan has been a faculty member in the Department of Chemical Engineering at the University of Utah. He has a Ph.D. in Civil Engineering from the University of Toronto, awarded in 1980. He has more than thirty-five years of experience with petroleum service and technology companies. He worked for Dowell and Dowell Schlumberger in Denver, Tulsa, and Houston, with TerraTek in Salt Lake City, Advantek International in Houston, and ASRC Energy Services in Anchorage. He has worked on projects concerned with subsurface energy recovery and storage (hydrocarbon, geothermal) in a variety of reservoir environments throughout the world. He is a co-principal investigator for the DOE FORGE project (Frontier Observatory for Research in Geothermal Energy).
