Frac Induced Failures and Investigations

Abstract:
This presentation reviews events and subsequent investigations related to tubular failures in horizontal multi-frac projects. Specific steps from initial information from the rig site or recovered (fished) pieces to material and fracture face examination are documented with photos for each step of the procedure. Participants will come away with an appreciation of how a failure can be turned into a learning opportunity and avoid similar mishaps in the future. A comprehensive data base allows us to not only show examples but characterize the most common causes of problems. Case studies picked from 40 years of failure investigations in the Permian, Eagle Ford, and Haynesville are reviewed for lessons learned.
