R-Type Casing Packer
Compression-set retrievable service packer
Description
The R-Type Casing Packer is a mechanical set double grip service Packer used in production, stimulation and testing applications. The Packer features a large internal bypass flow path to prevent swabbing during the trip in or out of the well.
Tubing pressure acts against the balance piston and engages the collete to prevent the bypass from being opened during injection operations. Additionally, tubing pressure engages the hydraulic hold down buttons into the casing to prevent the Packer from being pumped out of the well.
The Packer is set by right-hand rotation and slacking off the required weight to pack off the annulus. To unset the Packer, pick up the string to open the bypass. Continue pulling until the string is free. The J-Body Mechanism will automatically reset to the run-in hole position.
