• Simple Straight-Pull Release: A key feature is the adjustable straight-pull release mechanism, which is controlled by a set of shear screws. This allows for a simple and reliable method to unseat the packer with a pre-determined upward force, ensuring easy and predictable retrieval.
• Pressure-Activated Setting: The packer is set by applying tubing pressure, which is then locked in place by a body lock ring, eliminating the need for tubing manipulation or rotation.
• Integrated By-Pass: Features a large internal by-pass that minimizes the swabbing effect during run-in and retrieval, allowing for faster and safer operations.
• Adjustable Shear-Release Value: The number of shear screws can be adjusted on-site to control the release force, providing flexibility to match specific well conditions.
• Double-Grip System: This packer is designed with a double-grip system, utilizing slips to hold from both above and below, which securely anchors the tool in the casing and prevents movement under pressure.
• General Production and Injection Wells: A highly versatile packer suitable for a wide range of conventional production and injection applications.
• Well Stimulation: Used to isolate the treatment zone during fracturing, acidizing, or other stimulation operations where a secure but retrievable seal is required.
• Zonal Testing: Ideal for testing formation integrity or for temporary zonal isolation during wellbore evaluation.
• Perforating Operations: Can be used as a support packer during tubing-conveyed perforating (TCP) to anchor the tubing string and provide a stable platform.
The Kriloha K-Packer™ RHP-SPR Hydraulic Set Retrievable Packer is a testament to Kriloha Ltd.’s philosophy of combining robust performance with operational simplicity. This packer is a cornerstone of our completion equipment portfolio, designed to be the versatile workhorse for a wide array of production, injection, and well intervention applications. Its primary advantage is the simple and reliable hydraulic-set, straight-pull release mechanism. To set the packer, tubing pressure is applied from the surface. This pressure actuates the packer’s slips and sealing element, and a body lock ring ensures that the setting force is held securely, preventing accidental unsetting. This hydraulic setting method eliminates the need for jarring, rotation, or complex tubing manipulation, which saves valuable rig time and reduces the risk of tool damage. The true genius of the RHP-SPR lies in its straight-pull release. The packer is retrieved by applying an upward pull on the tubing string, which shears a series of screws and releases the slips. The shear value is fully adjustable on-site, allowing operators to fine-tune the release force based on specific well conditions and the expected differential pressure. This ensures that the packer can be released cleanly and predictably, without excessive force that could damage the tubing string or other downhole equipment. The RHP-SPR is engineered with a double-grip system, featuring slips that hold the packer securely against both upward and downward pressure differentials. This bidirectional anchoring provides superior stability and prevents packer movement during high-pressure stimulation treatments or periods of high production. A large internal by-pass is integrated into the design, which is a critical feature for mitigating the “swab-off” effect. As the packer is run into the hole or retrieved, the by-pass remains open, allowing fluids to equalize across the tool and preventing premature setting due to pressure buildup. Once the packer is set, the by-pass automatically closes, creating a positive seal. This feature not only enhances safety and reliability but also allows for faster trip speeds, further reducing operational time and costs. The RHP-SPR is suitable for virtually any production application and is particularly valuable in scenarios where multiple zones require isolation, or where repeated setting and retrieval is anticipated, such as in testing or stimulation programs. Its proven design and field-adjustable features make it a highly adaptable and economical choice for a variety of well completions. At Kriloha Ltd., we have engineered the RHP-SPR to be a packer that you can trust. It is designed and manufactured to the highest industry standards, ensuring its performance in the most challenging environments. With our dedicated technical support and a global inventory, we can provide the right solution for your specific needs, helping you maximize your well’s productivity and extend its operational life.
