These GSB Packers feature the largest possible bore through combined packer and seal accessory. The GSB Packer is run to depth, connected to the tubing with a Model K or KC Anchor Tubing Seal Nipple, and is set by applied tubing pressure. This makes the packer ideal for use in high angle deviated wells common in offshore operations.
High-strength, slender structure, sealing elements resist suction.
Safety of flanged up completions permits displacing tubing before setting packer.
Two opposed sets of full-circle, full strength slips assure that the packer will stay where it is set.
Unique interlocked, expandable metal back-up rings contact the casing and create a positive barrier to packing element extrusion.
Improved ratchet lock rings ensure smooth setting and maintain setting unload.
The pipe string needs to be rotated or moved up and down while setting , which can reduce the length and setting problems.
All O-rings are backed by gaskets for improved long-term sealing reliability.
Improved mechanism design reduces packer leak points while ensuring adequate setting load.
The GSB packer is designed with a maximum pressure capacity of 10,000 psi.
Special joints can be provided to connect other components such as milling extension barrels to facilitate the milling and unsetting of the packer in special condition.
The one-piece alloy steel central tube meets the requirements of the hydrogen sulfide operating standard ISO15156-1-2015.
High pressure testing of anchorage seal assemblies, packers and other components can be performed before running.
