The Evolution Model EW-2 Lock Mandrel has two up-facing locking dogs to prevent upward movement and a No-Go shoulder to prevent downward movement.

The Baker®-style EW-2 Lock Mandrel have a larger OD dimension near the top of the lock mandrel which No-Go’s with the top of the nipple profile sealing bore.  This prevents downward movement when locked in the nipple profile.

Operation

The EW-2 Lock Mandrel is run downhole with the EC-1 Running Tool with appropriate locator ring.

The made-up tool string is lowered in the well to just above the desired seating nipple, and then the tool string weight is now taken up.

The Lock Mandrel is then set in the seating nipple profile with moderate downward jarring. Upward strain will indicate the EW-2 has locked in the nipple. Subsequent upward jarring will shear the running tool pins, releasing the EC-1 Running Tool from the lock assembly. Once the shearing sequence is complete the EW-2 Lock Mandrel will be retained in the profile nipple.
