We investigate the potential of ground source heat exchangers (GSHE) for HVAC, particularly in cooling applications, in the tropical environment of Hawai‘i. Recent studies in Southeast Asia showcase the capacity of GSHE for space cooling in tropical environments (Yasukawa and Uchida, 2018). In Ha...

Much of the focus surrounding geothermal energy resource utilization has been on high enthalpy resources for electrical power generation – these systems are typically restricted to regions with high heat flow. However, there exists a much more extensive set of geothermal resources that can be emp...

With the increasingly serious environmental pollution, the utilization of clean resources such as geothermal energy is gradually increasing. Building heating is the main application mode of geothermal energy, but the existing geothermal energy heating system is mainly based on a single mode. Its ...

Fourth generation district heating (4GDH) materials technology and methods are making previously uneconomic conventional geothermal resources feasible for district heating development. Numerous low-temperature conventional geothermal resources exist near communities in the Western United States. ...

An intergranular aquifer in the Zeta Valley (Montenegro) represents one of the largest groundwater reservoirs in the region. The depth to the water table is around 20 m on average, so the temperature of the groundwater remains almost constant throughout the year (around 14°C). The quantitative an...

The harsh downhole conditions of high pressure and high temperature (HPHT) encountered in geothermal wells make the drilling operation a challenging task. Drilling in such environments requires a special drilling fluid formulation with high thermal stability and good rheological properties to ful...

The goal of this research is to develop wellbore barrier materials with robust zonal isolation, mechanical integrity and durability. In order to achieve the aforementioned objectives, oil cementing systems were selected based on their influence on strength retrogression, high temperature degradat...

Distributed Acoustic Sensing (DAS) is a recently developed method which utilizes short pulses of laser light to measure strain at thousands of locations along an optical fiber, effectively transforming fiber optic cables into massively distributed arrays of seismometers. We are exploring the use ...

Exploration for Geothermal Resources shares many of the same risks as exploring for minerals or oil. As such, the geothermal industry is also seeing the adoption of technologies developed in the oil exploration industry. De-risking the early phase of exploration for suitable geothermal sites requ...

Toward Constraining Major Fault Zone and Heat Source Structures Beneath the Mineral Mountains and Roosevelt Hot Springs Area, Utah

The Utah Frontier Observatory for Research in Geothermal Energy (FORGE) was selected in 2018 by the U.S. Department of Energy to explore the technological feasibilit...

In fracture-dominated reservoirs, studies allude to the spatial variation of fracture surfaces across different scales, and have demonstrated that variation in fracture aperture can lead to flow channeling. For geothermal energy production, the flow-wetted surface area is of particular interest, ...

Interpretation of In-Situ Stresses at the Utah FORGE Site using Pressure and Temperature Signatures

In Sept 2017, an injection program was carried out in the openhole toe (Zone 1) of Well 58-32 at the Utah FORGE site. Zone 1 in Well 58-32 encompasses all of the approximately 147 feet of open hol...
