4 Type H & National back pressure valve profiles are required. Type H & National back pressure valve profiles are required. An extended neck hanger is required for adapter flange removal. An extended neck hanger is required for adapter flange removal. Requirements Copyright by B&B Oilfield Services, Inc. 2009

5 Hydraulic forces pushing against back pressure valve Hydraulic forces pushing against back pressure valve threads separating wellhead flanges or tree valves with forces up to 160,000 lbs. Separation can take place at any vertical run flange of Separation can take place at any vertical run flange of the tree assembly. Separation is not limited at the tubing spool and the Separation is not limited at the tubing spool and the tubing head adapter. Tree Jack assembly is installed onto the threads of the Tree Jack assembly is installed onto the threads of the tree cap. How it works Copyright by B&B Oilfield Services, Inc. 2009

6 Determine Tree Jack pusher rod length by measuring 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 push rod into back pressure valve threads. Install Tree Jack over push rod and secure to tree cap Install Tree Jack over push rod and secure to tree capthreads. Apply pressure to the upper hydraulic connection Apply pressure to the upper hydraulic connection generating up to 160,000 lbs. of separation force. Once tree is separated, dismantle Tree Jack and Once tree is separated, dismantle Tree Jack and remove tree from well. How it works Copyright by B&B Oilfield Services, Inc. 2009
