Interpreting Diagnostics Fracture Injection Tests (DFIT)
Disciplines: Completions | Reservoir
Course Description
Diagnostic fracture injection tests (DFITs) are fracture-injection tests used to estimate stress, pore pressure, and permeability. In a typical procedure, 5-300 bbl of fluid is injected to create a small fracture. Then, pressure is monitored for hours, days, or weeks after shut-in. In this course, I outline modern best-practices for estimating key parameters from a DFIT. Topics include: (a) preparing data and understanding context, (b) diagnosing trends in the pressure transient, (c) the influence of permeability, injection volume, and wellbore orientation on the observed transient, (d) estimating stress, (e) estimating pore pressure, (f) estimating permeability, and (g) identifying common 'gotchas'. The course covers the fundamental physics and derivations that explain DFIT phenomena. Finally, the course reviews interpretation of DFIT-FBA, flowback tests that can be used to accelerate the test.

Instructor
Mark McClure established ResFrac in 2015 to help operators maximize value through the application of advanced geomechanics and reservoir simulation. Before founding ResFrac, Mark was an assistant professor at the University of Texas at Austin in the Department of Petroleum and Geosystems Engineering. After earning a Bachelor of Science in chemical engineering and a Master of Science in petroleum engineering from Stanford University, Mark earned a PhD in energy resources engineering at Stanford. Mark has earned multiple awards, including the Hank Ramey Award from Stanford University, Best Paper in Geophysics, three outstanding paper awards at URTeC, Hart Energy 40 Under 40, SPE Regional Awards for Completions Optimization and for Young Member Service, and SPE’s TWA Energy Influencers award. On four occasions, he has received recognition from journals as an outstanding reviewer. Mark is the Chairperson for the SPE Golden Gate Section and the 2024 Western Regional Meeting.
