Single Grip Retrievable Packer

Our Single Grip Retrievable Packer (Model R-3S/GR-3S Series) is a field-proven, compression-set mechanical production packer, widely recognized as the industry-standard downhole tool for conventional oil and gas well completion and workover operations. Designed with a single-direction rocker slip anchoring system and high-reliability sealing assembly, this packer delivers robust annulus isolation between the tubing and casing, with simple rig-site operation, excellent retrievability, and repeatable setting performance.

With a streamlined structure and universal interchangeable design, our single grip retrievable packer is compatible with most international mainstream brand equipment, significantly reducing your inventory cost and maintenance downtime. It is the ideal cost-effective solution for low-to-medium pressure oil and gas production operations worldwide, both onshore and offshore.

1.Field-proven 3-element packing system : Ensures reliable, long-term sealing under downhole conditions; standard NBR elastomer rated to 148°C (300°F), with high-temperature HNBR/FKM options available up to 204°C (400°F) for extreme well environments.
2.Large-area bypass valve with equalizing function : Enables rapid pressure equalization across the packer, minimizes swabbing effect during run-in and retrieval, accelerates tripping speed, and prevents accidental damage to the packing element.
3.Rocker-type slip with carbide inserts : Anchors securely in all casing grades (including premium casing), delivers stable holding force, and ensures smooth, jam-free release with zero stuck-pipe risk.
4.Automatic J-type locking mechanism : Enables one-step setting and releasing, supports multiple resetting operations downhole without pulling the tubing string, drastically reduces rig time and operation cost.
5.Standard 1/4 right-hand turn setting : Extremely simple operation with minimal training required for rig crews, eliminates human error and ensures consistent setting performance.
6.Differential lock design : Automatically locks the bypass valve closed during high-pressure operations, maintains sealing integrity, prevents production loss, and avoids unnecessary workover operations.
7.Long-stroke mandrel : Allows fluid circulation without releasing the packer, simplifies wellbore circulation procedures and improves operational flexibility.
8.100% interchangeable parts with global mainstream brands : Full compatibility with Baker Hughes, Halliburton, and Weatherford equivalent models, reduces your spare parts inventory pressure and replacement cost.

Q: What is a Single Grip Retrievable Packer, and how does it differ from a double grip packer?

A: A Single Grip Retrievable Packer is a compression-set mechanical downhole tool with a single-direction slip anchoring system, designed to isolate the tubing-casing annulus in conventional oil and gas production. It is set via tubing weight, ideal for low-to-medium pressure operations where pressure differential is primarily from above the packer. In contrast, a double grip packer features bi-directional slips to withstand pressure from both directions, making it suitable for high-pressure stimulation operations. The single grip model offers a simpler structure, easier operation, and lower cost, making it the preferred choice for routine production applications.

Q: What is the maximum working pressure and temperature of your Single Grip Retrievable Packer?

A: Our standard model has a rated working pressure of 35MPa (5000psi) and a standard temperature rating of 148°C (300°F). For extreme well conditions, we can customize high-performance versions with a pressure rating up to 70MPa (10000psi) and a temperature rating up to 204°C (400°F) to meet your specific downhole requirements.

Q: What casing sizes are available for this packer?

A: Our standard production range covers 4" to 9 5/8" casing sizes, which are the most widely used in global oil and gas fields. We also provide full customization for non-standard casing sizes to fit your unique wellbore specifications.

Q: Can this packer be reset multiple times downhole?

A: Yes. Equipped with an automatic J-type locking mechanism, our Single Grip Retrievable Packer supports multiple setting and releasing operations downhole without pulling the tubing string. This feature significantly reduces rig time and operation costs, especially for multi-zone operations that require repositioning.

Q: Are your packer parts interchangeable with other international mainstream brands?

A: Yes. All components of our Single Grip Retrievable Packer are designed to international universal standards, and are 100% interchangeable with equivalent R-3S series models from Baker Hughes, Halliburton, Weatherford, and other global mainstream brands. This compatibility greatly reduces your spare parts inventory pressure and replacement costs.

Q: How to choose the right Single Grip Retrievable Packer for my well?

A: To provide you with the optimal model and configuration, please supply the following key well parameters: casing size and weight, wellbore inner diameter, tubing thread connection type, required working pressure, maximum downhole temperature, and well fluid properties (including H2S/CO2 content for corrosive environments). Our technical team will tailor the perfect solution for your specific operation.

Q: What is the lead time for standard and customized orders?

A: For standard size Single Grip Retrievable Packers, we maintain sufficient inventory for immediate delivery. For customized orders, the typical lead time is 15-30 working days, depending on the complexity of the customization and order quantity. We will provide a detailed delivery schedule upon order confirmation.

Q: What after-sales support do you provide?

A: We provide full lifecycle after-sales support, including 24/7 technical consultation, on-site operation guidance, and maintenance training. Our engineering team can also provide customized downhole operation solutions and troubleshooting support to ensure the smooth operation of our products in your well.

Q: Is this packer suitable for deviated and horizontal wells?

A: Our standard Single Grip Retrievable Packer is suitable for vertical and low-angle deviated wells. For high-angle deviated and horizontal wells, we can provide optimized designs with enhanced slip anchoring and setting performance to ensure reliable operation in complex well trajectories.

Q: What testing is performed on each packer before delivery?

A: Every unit undergoes a full series of factory tests before delivery, including hydrostatic pressure test (to verify sealing performance), dimensional inspection (to ensure compliance with API standards), magnetic particle inspection (MPI), and ultrasonic non-destructive testing (to detect material defects). We provide a full set of test reports with each shipment for your quality traceability.
