• Single-Grip, Mechanical Set: Set by a simple 1/4 right-hand turn and applied weight. It features a single set of slips that hold the packer from above, making it ideal for applications with pressure from the production zone.
• Large By-Pass: A large internal by-pass is a key feature, allowing for rapid fluid equalization during run-in and retrieval, reducing the swabbing effect and increasing operational efficiency.
• Tubing Pressure Actuated Collet Lock: This feature eliminates the need for excessive set-down weight to maintain the pack-off, as tubing pressure is used to engage a collet lock, providing a secure setting.
• Simple Release: The packer is released by simply picking up the tubing string, which opens the by-pass and releases the slips. The J-slot mechanism automatically resets to the running position.
• Interchangeable Components: The design allows for interchangeable parts with other manufacturers, which can help reduce inventory costs and simplify logistics for operators with mixed fleets of equipment.
• Low-Pressure Conventional Completions: Ideal for wells where the pressure differential is from below the packer, such as in low-pressure production zones.
• Well Testing: A reliable choice for temporary zonal isolation during well testing and evaluation.
• Perforating Operations: Used to provide a stable anchor for the tubing string during perforating, especially when the well is expected to flow after perforating.
• As an Upper Packer: Can be used as an upper packer in dual or multi-packer completions where the primary seal is provided by a lower packer.
The Kriloha K-Packer™ Single Grip Retrievable Packer Model ‘R’ is the quintessential single-grip compression-set packer, expertly designed by Kriloha Ltd. to provide an economical yet highly reliable solution for a variety of well completions. While it shares the same robust DNA as its double-grip counterpart, the single-grip version is specifically tailored for applications where the primary pressure differential is expected to come from below the packer, such as in standard production or well testing scenarios. The mechanical setting procedure is both simple and effective. A mere one-quarter right-hand turn of the tubing string at the desired setting depth, followed by slacking off a pre-determined amount of weight, engages the slips and compresses the three-element packing system. This action creates a secure seal against the casing. The straightforward nature of this process makes it a favorite among rig crews and minimizes the potential for operational errors. A critical feature of the Single Grip Model ‘R’ is the tubing pressure-actuated collet lock. This innovative mechanism allows the operator to maintain the pack-off without the need for continuous or excessive set-down weight from the rig. As pressure builds in the tubing, the collet is locked into position, effectively holding the packer in its set state. This not only enhances the security of the seal but also reduces stress on the tubing string and improves the overall efficiency of the operation. The single-grip design with a set of slips above the packing element is perfectly suited for holding against upward forces, making it an ideal choice for low to moderate-pressure production wells where the reservoir is expected to provide the primary pressure from below. The packer also incorporates a large internal by-pass to facilitate fast and safe run-in and retrieval. This by-pass minimizes the “swab-off” effect, which is the pressure differential created by the tool’s movement through the wellbore fluid. By allowing fluids to equalize, the by-pass prevents premature setting and potential damage to the sealing element. The by-pass is automatically opened when the tubing is picked up to release the packer, ensuring a smooth and easy unsetting process. The retrieval of the Single Grip Model ‘R’ is as simple as its setting. A straight upward pull on the tubing string unsets the packer, and the J-slot mechanism automatically resets for the next run. This allows for repeated setting and unsetting in a single trip, making it an extremely versatile tool for wellbore cleanouts, repeated well testing, or zone isolation during stimulation. The Kriloha K-Packer™ Single Grip Model ‘R’ stands as a testament to our engineering prowess—a tool that is both highly functional and economically viable. We have built this packer to meet the demands of modern oilfield operations, providing a reliable, safe, and efficient solution for a wide range of completions. Our commitment to quality and comprehensive technical support ensures that every single-grip packer delivers the dependable performance that is the hallmark of a Kriloha Ltd. product.
