DFIT
Diagnostic Fracture Injection Test. A subsurface well test in which pressure is monitored as a small volume of fluid is injected into a reservoir to develop a hydraulic fracture. Monitoring continues to produce a pressure versus time plot that is analyzed to determine reservoir properties, formation pressure, and stress regime.

Word of the Week – Stable Isotopes
Stable Isotopes Refers to non-radioactive isotopes of elements, including those of oxygen, hydrogen, carbon, sulfur, and nitrogen. In geothermal geochemistry, the stable isotope ratios of oxygen (18O/16O) and hydrogen (2H/1H) in thermal waters are used to trace its...
