Re-Fracturing - Candidate Selection and Design

Disciplines: Production and Operations

Course Description

This course discusses how to select a candidate that will benefit from a workover and the extra considerations involved in a treatment design.

  • What makes a good re-frac candidate
  • How depletion affects the re-fracture for good and bad
  • Re-fracture treatment design differences

Learning Level

Intermediate (Useful to be familiar with fundamentals of hydraulic fracturing)

Course Length

1 Day

Why Attend

If you are considering the possibilities of re-fracturing operations, it is critical to understand all the various conditions that must be considered. These include: geomechanics of how production from this and offset wells may have changed in situ stresses, how proppant from the original frac may impact fracture propagation for the re-frac, and understanding specifically what must be accomplished by the re-fracture treatment (make longer fractures, inject stronger proppant to restore kfw, fracture new rock, …).

Who Attends

This course is of interest to petroleum engineers involved (directly or indirectly) in candidate selection, design and evaluation of re-fracturing treatments. It would be beneficial for participants to have a basic understanding of hydraulic fracturing and well completion concepts. However, the course is also of interest/value for reservoir engineering and management to understand what potentially can (and cannot) be achieved with re-fracturing.


0.8 CEUs (Continuing Education Units) will be awarded for this 1-day course.
