The team held a public Town Hall in Milford, UT to share the breakthroughs and future plans of Utah FORGE in a casual, relaxed setting.
Geothermal Glossary
Word of the Week – Granitoid
Granitoid A generic term referring to hard, coarsely crystalline plutonic rock that is produced by intrusion of magma followed by a long period of slow cooling and solidification below the...
Word of the Week – Heat Exchanger
Heat exchanger A device or engineered system that is used to transfer thermal energy in soil, rock or produced fluid to heat a closed loop through which another fluid is circulated. Heat...
Word of the Week – Heat Mining
Heat Mining The process of extracting geothermal heat by the heating of initially cold water that flows through fractures in hot rock below the surface. Heat transfer is achieved by...
Word of the Week – Helium Isotopes
Helium Isotopes Helium gas is a trace constituent of groundwater and thermal fluids, and the ratio of 3He to 4He can be measured with a high-precision mass spectrometer to determine whether...
Word of the Week – Hot Dry Rock
Hot Dry Rock Hot crystalline rock with essentially no porosity and lacking producible hot water. Geothermal production from hot dry rock reservoirs is the primary goal of EGS (enhanced...
Word of the Week – Hydraulic Fracture
Hydraulic Fracture A rock-hosted tensile fracture that is created by injection of fluid under high pressure.
Word of the Week – Hydraulic Gradient
Hydraulic Gradient The slope on the water table which promotes horizontal fluid flow in permeable rock units.
Word of the Week – Hydrothermal Eruption
Hydrothermal Eruption Rare explosive discharge of hot water and steam that is powerful enough to excavate a crater and lift rock fragments and its pulverized equivalents into the air to...
Word of the Week – Illite
Illite A potassium-bearing mica-like clay mineral that is a product of hydrothermal alteration. It commonly replaces feldspars and other alumino-silicate minerals and it forms above ~220°C....
Word of the Week – INSAR
INSAR Interferometric synthetic aperture radar is a technique that is deployed from aircraft or satellites in order to generate interferogram images. These are used to interpret surface...
Word of the Week – Interlayered Clay
Interlayered Clay A mixture of different clays such as illite, chlorite, and montmorillonite that are structurally interlayered and form via rock alteration at moderate temperatures in...
Word of the Week – Lava Flow
Lava Flow A product of an erupting volcanic cone or fissure made up of liquid molten rock that flows downhill and eventually solidifies due to cooling.
