DFIT Diagnostic Fracture Injection Test

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 – Scale

Word of the Week – Scale

Scale Refers to deposition of minerals (e.g., calcite, silica, anhydrite, clays) in the well and reservoir that reduce permeability and block fluid channels.

Word of the Week – Seismometer

Word of the Week – Seismometer

Seismometer An instrument that records ground movement most often caused by earthquakes, volcanic eruptions and quarry or mine blasts. Short period seismometers detect seismic events that occur within a few hundred kilometers, whereas broadband seismometers detect...

Word of the Week – Shear Fracture

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.
