Diagnostic fracture injection test in a Cartesian plot.

Aside from the diversity of terminology, the diversity of plotting techniques is the aspect of DFIT analysis that most often causes confusion. Why don’t we just make a Cartesian plot of pressure […]

Diagnostic Fracture Injection Tests: The Basics

A typical pressure response during injection in a DFIT.

In a diagnostic fracture injection test (DFIT), a relatively small volume of fluid is injected into the subsurface, creating a hydraulic fracture. After the end of injection, the pressure in […]
