AS-4 10K Compression Set Packer


The T609 AS-4 Double Grip, Compression Set Packer is used for production, stimulation, TCP and testing. The AS-4 is ideally suited for installations where the packer is run, the well perforated, treated, swabbed and put on production. A large mandrel matching the tubing I.D. gives unrestricted flow and allows the passage of wireline tools and other accessories. An internal by-pass valve reduces the swabbing effect when running or retrieving the packer. Set down weight closes the by-pass valve, sets the upper and lower slips and energizes the packing elements. The by-pass, located near the packing elements allows debris to be washed from the upper slips when the packer is released. The AS-4 also features an upper slip releasing system that reduces the force required to release the packer.
