• Mechanical Set: Set by a simple 1/4 right-hand turn and subsequent weight-down on the tubing string. This mechanical setting is a field-proven method that is reliable and easy to operate.
• Double-Grip System: Features two sets of slips that hold against pressure from both above and below, providing a secure anchor for the tubing string.
• Hydraulic Hold-Down: An integrated hydraulic hold-down mechanism below the packing element prevents the packer from being unseated or moved by upward pressure differentials.
• Large By-Pass: A large internal by-pass allows for rapid fluid equalization during run-in and retrieval, reducing the swabbing effect and allowing for faster trip speeds.
• Long-Stroke Mandrel: The long-stroke mandrel simplifies fluid circulation and facilitates the setting and unsetting process without packer release, offering operational flexibility.
• Conventional Production Wells: The primary use for this reliable workhorse packer in a wide range of conventional production applications.
• Testing and Stimulation: Ideal for well testing, acidizing, and fracturing treatments where a secure, bidirectional seal is required for temporary operations.
• Tubing-Conveyed Perforating (TCP): A popular choice for TCP operations as it provides a stable anchor for the tubing and allows for pressure isolation.
• Multi-Zone Completions: Can be used as a temporary or permanent upper packer in multi-zone completions to isolate zones for selective production.
The Kriloha K-Packer™ Double Grip Retrievable Packer Model ‘R’ is a time-tested workhorse in the world of oil and gas completions, embodying the principles of rugged reliability and straightforward operation. It is one of the most widely used packers in our fleet, renowned for its versatility and proven performance. The Model ‘R’ is a mechanically-set packer that provides a robust, bidirectional seal against the casing, making it a staple for a broad range of production and intervention applications. Setting the Model ‘R’ is a simple and intuitive process: a quarter right-hand turn of the tubing string, followed by slacking off the required weight. This action engages the slips and compresses the three-element packing system, creating a secure, pressure-tight seal against the casing. This mechanical setting method is reliable, predictable, and provides clear surface indications, giving operators confidence in the integrity of their completion. The double-grip design is the key to the Model ‘R’s’ exceptional performance. Featuring two sets of slips—one above the packing element and one below—the packer is anchored securely against pressure from both directions. This is particularly important during stimulation treatments, where high pressures are applied from the surface, or in wells with high bottom-hole pressures that exert upward forces on the packer. The integrated hydraulic hold-down mechanism provides an additional layer of security. This feature, which is activated by tubing pressure, ensures that the packer remains securely anchored and prevents it from being pushed up the wellbore. The Model ‘R’ also boasts a large internal by-pass system. This by-pass remains open during run-in and retrieval, allowing fluids to equalize and preventing the “swab-off” effect that can prematurely set the packer or damage the sealing elements. The large flow path not only enhances safety and reliability but also allows for faster trip speeds, saving valuable rig time. Once the packer is set, the by-pass is automatically closed by a balanced sleeve, maintaining the integrity of the seal. The long-stroke mandrel is another feature that enhances the packer’s versatility. It allows for fluid circulation and spotting of chemicals without releasing the packer, which is a major advantage during well treatments or workovers. The Model ‘R’ is fully retrievable, and its unique J-slot mechanism automatically resets to the running-in position when the tubing is picked up and moved. This allows for multiple setting and unsetting cycles in a single run, making it an ideal tool for repeated testing or treatment applications. At Kriloha Ltd., the Model ‘R’ is more than just a packer; it’s a legacy of dependable performance. Its rugged design and simple operation make it the go-to choice for a wide variety of conventional well completions, providing a secure and reliable foundation for your production or intervention goals. Our commitment to quality ensures that every Model ‘R’ packer is built to last and perform flawlessly, delivering the peace of mind that comes with using a Kriloha product.
