Mechanical Set Single Grip Retrievable Packer (Single Grip R-3)

This is a Single grip, compression set and retrievable packer (Single Grip R-3)

This packer is a retrievable set-down packer that features a large bypass area. The bypass area is controlled by a face-seal type bypass valve which is actuated by a 30” inch stroke mandrel. The Packer is available in a single-grip version for use as a conventional long-stroke production packer and in a double-grip version (with hold-down buttons) for combination production and well stimulation operations. The double-grip packer are used where pressure differential from below the packer is anticipated, features an integral hydraulic hold-down buttons that is located below the bypass valve. The double-grip packer also incorporates a unique built-in “differential lock” that utilizes a balance sleeve actuated by pressure from below the packer. This pressure creates an additional downward force which, combined with set-down weight helps to maintain the force necessary to keep the bypass valve closed.

Features/Benefits:

• Differential lock helps keep the by-pass closed and locked to the mandrel during high pressure operations.
• Automatically returns to run-in position when moved up the hole.
• Hydraulic hold-down buttons for differential pressure from below.
• Long stroke mandrel simplifies circulation of fluids without releasing the packer.
• Large by-pass allows speedy equalization of fluids.
• Rocker type slips.
• Standard right-hand set, optional left-hand set.
• Parts are interchangeable with other manufacturers.
