Word of the Week – Drill Cuttings
Drill Cuttings Small chips of rocks (e.g., <1/8 inch or <3 mm) obtained during drilling with a rotary bit that are continuously returned to the surface by the circulation of mud. Drill cuttings are the main source of geological and stratigraphic interpretation...
Word of the Week – Enhanced Geothermal System
Enhanced Geothermal System Unconventional geothermal resources that contain heat similar to conventional hydrothermal resources but lack the necessary groundwater and/or rock characteristics (e.g., permeability) to enable energy extraction without stimulation.
Word of the Week – Epidote
Epidote Alumino-silicate hydrothermal mineral having a distinctive yellow-green color that is used a mineral geothermometer, forming at temperatures above ~230°C. The first down hole occurrence of epidote commonly coincides with the top of a high-temperature...
