Tree Jack Application
  • Safely separates & removes wellhead & tree components during P&A or major maintenance operations.

slide3
Why use the Tree Jack
  • Saves time and $$$ by separating and removing wellhead components without the use of work over rig.
  • Reduces rig up time.
  • Reduces shock load on cranes while attempting to separate tree from wellhead.
  • Safe System – Minimizes exposure of personnel to typical hazards associated with removing wellhead components.
  • Verifies that tubing hanger is free & tubing has been properly cut.

Requirements
  • Type H & National back pressure valve profiles are required.
  • An extended neck hanger is required for adapter flange removal.

slide5
How it works
  • Hydraulic forces pushing against back pressure valve

threads separating wellhead flanges or tree valves with

forces up to 160,000 lbs.

  • Tree Jack assembly is installed onto the threads of the

tree cap.

  • Separation can take place at any vertical run flange of

the tree assembly.

  • Separation is not limited at the tubing spool and the

tubing head adapter.

slide6
How it works
  • Determine Tree Jack pusher rod length by measuring

from back pressure valve threads to approximately two

thirds to three quarters of Tree Jack window.

  • Install push rod into back pressure valve threads.
  • Install Tree Jack over push rod and secure to tree cap

threads.

  • Apply pressure to the upper hydraulic connection

generating up to 160,000 lbs. of separation force.

  • Once tree is separated, dismantle Tree Jack and

remove tree from well.
