Running  The ELWE is run using an EC-1 Running Tool. Tool. It is run downhole until the no-go shoulder on the ELWE locates above the upper seal bore of a Sliding Sleeve. The trailing dogs in the ELWE expand into the locking profile in a Sliding Sleeve, securing the ELWE Separation Sleeve in place. Downward jarring shears pins in the Running  Tool, releasing it from the Separation Separation Sleeve.

Pulling  To pull an ELWE, run in with a model EA Guide Guide and an EA Equalizing Prong down onto the Separation Sleeve. The Equalizing Prong will break off an equalizing plug inside the bore of the Separation Sleeve, allowing equalization to begin. Retrieve the EA Guide/EA Equalizing Prong to surface, and when equalized, then run back downhole again with an ERB Pulling Tool having an attached EB probe.  This will latch onto the fishneck of the ELWE ELWE Lock Mandrel while simultaneously collapsing the locking dogs, releasing the Separation Sleeve to be retrieved from the well.
