Casing Deformation Workgroup

Welcome to the Casing Deformation Workgroup

SPE’s Well Integrity Technical Section is home to the Casing Deformation Work Group, which has a top-level mission of:
Reducing the impact and increasing the understanding of casing deformations limiting accessibility in multi-fractured horizontal wells.

Casing deformations occur in a wide variety of applications, including unconventional wells employing hydraulic fracturing technology. Deformations are more common in certain basins than others, are thought to have many sources, and can manifest in different ways during drilling, completion, and production operations. Although the issue is almost exclusively one of well functionality rather than well integrity, it is an important one for industry to continue to explore.

The Work Group is focused on achieving its mission by:

    • Capturing the industry’s current state of technology and best practices;
    • Identifying technology gaps and define future opportunities; and
    • Sharing and disseminating learnings.

Formed in 2021, the Work Group currently consists of a core group of volunteer SPE members that is committed to defining a path forward that will ultimately involve broader input from those interested in contributing to this effort. Initial work has focused on:

    • Defining common language that can be consistently used to describe casing deformations;
    • Surveying and organizing available literature and creating a compendium that can be broadly accessed; and
    • Establishing a structure for capturing key data related observed casing deformations that will facilitate root cause analysis, identification of key case studies, and provide a basis for future technical advancement.

The Work Group’s intent is to engage more broadly with SPE members though Conferences and by leveraging volunteer efforts as tasks are established.  See below for a list of our upcoming events:

Messages to the Workgroup Community

Building on ongoing activity within our Work Group and successful Special Sessions at HFTC 2022, ATCE 2022, and HFTC 2023, the following events are currently planned:

  • SPE Forum, Galveston, Texas – 2023-12-04 to 2023-12-07
  • HFTC 2024, The Woodlands, Texas – Special Session, 2024-02-08, 1 PM – 3 PM Central Time
    • This Special Session will involve presentations from Work Group members and other invited presenters, and will include a status update on its Technology Roadmap after the SPE Forum on the topic in December 2023.
