Geothermal energy is being pursued as a potentially abundant, renewable energy source. Geothermal becomes attractive over some other renewable sources because of its potential scalability to provide a significant replacement of base-load electrical demand through use of advanced technology known as Enhanced Geothermal Systems (EGS). EGS are fractured, hot-rock reservoirs that have been extract heat by the circulation of water between injection and
production wells. Based on a sponsored MIT study, the US DOE has identified seven key technology areas critical to commercial demonstration and operation of EGS. Among these are high-temperature well logging tools and sensors, including downhole temperature, pressure, flow and seismic sensors to better monitor fracture and water injection. Theses sensors must operate up to 300°C installed in well depths over 10,000 feet. The industry looks to refinement of high temperature oil and gas well sensors to bring into EGS.
QOREX has been very active in the development and successful launch of optical thermal and pressure sensors in the thermal recovery sector of oil and gas, that operate up to targeted EGS temperature and pressure regimes. QOREX is working with EGS partners to address the challenges unique to deploying these sensors in the required depths and well completion design.
