P&L R-3 DOUBLE GRIP PACKER

P&L R-3 DOUBLE GRIP PACKER
The P&L R-3 Double Grip Packer is a heavy-duty, retrievable, compression-set mechanical packer designed for high-performance production, stimulation, and testing applications. Engineered to withstand severe differential pressures, it delivers reliable downhole isolation, easy pressure equalization, and seamless retrieval across demanding wellbore environments.

Key Features & Advantages

  • Integrated Hydraulic Hold-Down: Secures the tool against high differential pressures from below, preventing upward movement during stimulation or production cycles.
  • Internal Differential Lock: Keeps the by-pass valve firmly closed and locked to the central mandrel under high-pressure operations to maintain reliable seal integrity.
  • Extended Stroke Mandrel: Simplifies fluid circulation and well control operations without releasing the setting mechanism.
  • High-Volume By-Pass: Features large fluid bypass channels to minimize swabbing during tripping and enable rapid pressure equalization prior to unseating.
  • Rocker-Type Slips: Ensures uniform load distribution against the casing wall for exceptional holding power and easy, reliable release.
  • Automatic Re-engagement: Returns directly to the run-in position when moved up the hole, enabling smooth repositioning or pulling out of the hole (POOH).
  • Universal Interchangeability: Fully compatible with industry-standard replacement parts, simplifies inventory management and field maintenance.
  • Flexible Configurations: Standard right-hand set control with optional left-hand set designs, along with large-bore variants (45RDL).

Operating Procedures

Setting Procedure
  1. Run-In: Lower the packer with the by-pass valve open to permit unrestricted fluid circulation through and around the tool. Run approximately 1 ft below the target setting depth.
  2. Positioning: Pick up the tubing string to the exact setting depth.
  3. Engagement: Rotate the tubing string to the right and apply set-down weight. This moves the J-pin clear of the J-slot and drives the cone under the slips.
  4. Packing Off: Apply the required set-down weight to close the bypass valve, set the upper/lower slips, and fully energize the packing element assembly:
    • 4-1/2″ – 5-1/2″: 7,000 lbs
    • 5-1/2″ x 2-7/8″: 5,000 lbs
    • 7″: 9,000 lbs
    • 8-5/8″: 11,000 lbs
    • 9-5/8″: 15,000 lbs
Releasing & Retrieval Procedure
  1. Unseating: Straight pick-up of the tubing string opens the internal by-pass valve, allowing fluid and pressure to equalize across the tool.
  2. Resetting to Running Position: Raising the tubing full-length pulls the slips off the casing wall and engages the J-pin back into the running slot automatically.
  3. POOH / Reposition: Once unseated, the packer can be safely repositioned higher up the wellbore or pulled to surface with open circulation.
