Performance By The Numbers

ISO-Flex™ High-Expansion Retrievable Bridge Plug

Overcomes Well Obstruction During Temporary Abandonment Workover, Operator Saves Six Rig Days


  • Perform a temporary abandonment in an injection completion by restoring its secondary barrier within the well. During a caliper-logging run for a previous workover operation, an existing nipple-profile was confirmed to be fully corroded and unusable. This made it impossible to install a standard slickline plug that met the operator’s well- abandonment regulation needs.
  • Install a reliable well barrier beyond the corroded nipple-profile obstruction using through-tubing techniques to overcome the challenge of not having a proper setting-profile within the well.

Our Approach

  • Following a thorough pre-job analysis to assess operator objectives and specific wellbore challenges, Weatherford well-services specialists formulated a nippleless well-barrier solution to address workover issues. The team selected the ISO-Flex high-expansion retrievable bridge plug for its ability to create a V0-rated, temporary barrier below restricted tubing with recoverable convenience. The ISO-Flex provides a mechanical barrier and large, direct-to-the-wellbore equalization area that is ideal for sub-hydrostatic applications. Its multi-conveyance methods allows for deep or shallow deployment, setting, and retrieval using industry-standard conveyance techniques.
  • A drift run was performed to ensure the well was clear of any obstruction. In addition, a caliper run was made to confirm the tubing conditions at the plug’s setting depth. The Weatherford team deployed the plug using wireline conveyance and the ISO-EasySet setting tool with an electromechanical, non-explosive setter to establish the barrier. Once the intended depth was reached, a setting command was sent from surface and the ISO-Flex bridge plug was set as planned.
  • After releasing the wireline cable from the plug, a pressure test was performed per the operator’s specifications to confirm plug effectiveness and that the temporary abandonment was successfully achieved.

Value to Customer

  • The ISO-Flex solution effectively created a temporary barrier below the restricted area with recoverable simplicity. This allowed the operator to save 21 operational rig days over the minimum time required by heavy workover operations.
  • The robust API 11D1 V0 well-barrier solution was deployed in the same operational timeframe as a standard profile dependent barrier, but with a greater level of reliability for the well-abandonment project.
