Improving safety in wireline operations

The Well-Centric Wireline Indicator & Safe Recovery Device-Resettable, or WISARD-R, is an innovative but simple passive device designed to improve safety and efficiency in wireline operations.

Situated within the lubricator, directly below the stuffing box, the purpose of the WISARD-R is to:

  • Provide the winch operator with a visual indication the toolstring is at the surface
  • Allow the operator to selectively hold and release the toolstring in the lubricator
  • Catch and hold the toolstring in the event of a wire break arising from incorrectly pulling the toolstring into the stuffing box

The passive design means that there is no need to arm or disarm the system. It will work as designed every time.
