The Hydraulic Tubing Anchor works on hydraulic pressure. When the differential pressure in the tubing string is greater than the pressure in the casing annulus, the piston will be actuated, pressing the live slip against the casing and holding the tubing string in tension.
The piston will start to move at 10 PSI with the holding power increasing as the differential pressure in the tubing string increases.
The holding power varies with depth and differential pressure between the casing and tubing. The anchor is individually sized for each application. A Load/Thrust calculation is run to ensure proper holding power in each installation.
Over 6000 Black Gold Hydraulic Anchors had been deployed worldwide, without any failing to work or lost in hole.
Black Gold Hydraulic Anchors have an o-ring and seal cup that work as the primary and secondary sealing components.
The seal cups and o-rings and made of 90 Shore, Military Grade Viton.
The Viton elastomers are good to 400 degrees Farenheit.
No, there are no restriction. The Anchor ID is slightly larger than the ID of the tubing.
As these anchors actuate on the differential pressure in the tubing string, they need to be placed above the pump. Place the hydraulic anchor as close to the pump as well conditions permit.
Yes, Tungsten carbide button fixed slips are available in most sizes and designed for P-110 casing.
Hydraulic anchors are sized dimensionally to casing drift. The amount of holding power needed is determined by the pump size and well conditions. You can go to the Black Gold app apps.blackgoldpump.com, submit the parameters and find out if the anchor you’ve selected has the proper holding power for your application.
No, that is not necessary. Since the anchor works off differential pressure when you draw the fluid level down and the tubing load increases the hydraulic tubing anchor will move down your casing, stretch the tubing, and all pull the tubing into tension. This is ideally for all applications to pull the tubing into tension slowly.
