Stored Heat
Calculated thermal energy stored in a volume of hot rock. It is calculated using the rock volume, porosity, rock density, specific heat of rock, and the difference between the reservoir temperature and the background temperature given by the geothermal gradient outside the resource area.
Geothermal Glossary
Word of the Week – Shear Fracture
Shear Fracture A pre-existing joint or fracture that accommodates shear displacement due to frictional slippage, wherein the rough surfaces on the fracture surface create permeability due to self propping.
Word of the Week – Silica Sinter
Silica Sinter Horizontally banded deposit of amorphous silica that precipitates around neutral pH hot springs that are close to boiling temperature.
Word of the Week – Slickwater
Slickwater Water that is injected during reservoir stimulation. It is modified with low concentrations of chemical additives, including polyacrylamide, that reduce friction and enhance fluid flow. Proppant (e.g., sand) is often added to help keep stimulated fractures...
