Retrievable Compression Packer

Our Retrievable Compression Packer is a heavy-duty, mechanical-set, fully retrievable downhole tool, engineered for oil and gas well completion, workover, zonal isolation, and stimulation operations. Manufactured in strict compliance with API Specification 11D1 (latest edition)American Petroleum Institute, this packer delivers reliable bi-directional pressure containment, superior annular sealing performance, and simple one-trip setting and retrieval.

Designed for versatility, it adapts to conventional wells, deviated wells, horizontal wells, and even high-pressure high-temperature (HPHT) well conditions. Its reusable structure and efficient operation significantly reduce rig time, lower operational costs, and minimize workover complexity, making it a preferred solution for onshore and offshore oilfield operators worldwide.

1.API 11D1 Compliant Design with V3 Grade Validation : Meets international oil and gas industry standards, ensuring predictable and reliable performance in critical downhole operations
2.Bi-directional Carbide Slip Anchoring Mechanism : Firmly grips the casing inner wall, withstanding differential pressure from both above and below the packer, eliminating movement risk during high-pressure stimulation
3.3-Piece High-Performance Elastomer Sealing Stack with Anti-Extrusion Back-up Rings : Delivers zero-leakage annular sealing, even under extreme pressure and temperature fluctuations, with extended service life
4.Built-in Large-Bore Bypass Valve System : Minimizes swabbing effect during running and retrieval, prevents formation fluid surge, and enables fast pressure equalization for simplified release
5.Simple Mechanical Setting & Retrieval : 1/4 right-hand rotation + weight set-down setting; direct pick-up for one-trip retrieval, no milling or special downhole tooling required
6.High-Strength Alloy Steel Mandrel : Superior tensile and compression load capacity, supports tailpipe hanging and multi-operation combined trips to cut down rig time
7.Positive Rotational Lock Internal Connections : Transmits extreme left/right-hand torque through the packer without loosening, adapting to complex downhole operation demands
8.Reusable Structure : Main body components can be reused for multiple operations after replacing wearing parts, greatly reducing equipment procurement costs

Q: What industry standard do your Retrievable Compression Packers comply with?

A: All our retrievable compression packers are designed, manufactured, and tested in strict accordance with API Specification 11D1 (latest edition) for oil and gas industry packers and bridge plugsAmerican Petroleum Institute. We also hold API Q1 and ISO 9001 certifications, with full product qualification documentation available upon request.

Q: What is the difference between a compression set packer and a tension set packer?

A: A compression set packer is set by slacking off tubing weight to compress the sealing element, and is optimized to withstand pressure from below the packer, making it ideal for stimulation, testing, and production operations. A tension set packer is set by pulling tubing tension, and performs better with pressure from above. Our compression packer features a bi-directional slip design, enabling it to withstand pressure from both directions for wider application.

Q: Can this packer be used in deviated or horizontal wells?

A: Yes. Our retrievable compression packer features a compact, short-length design and a reliable mechanical locking mechanism, fully compatible with deviated wells, horizontal wells, and extended-reach wells. The built-in bypass valve minimizes swabbing during running in complex wellbores, and the positive locking structure eliminates premature setting risk.

Q: How many times can the packer be reused after retrieval?

A: The main body, mandrel, slips, and cones are made of high-strength alloy steel, which can be reused for multiple operations after proper inspection and maintenance. Wearing parts (sealing elements, O-rings, back-up rings) must be replaced after each use to ensure reliable sealing. With standard maintenance, the main structure can be reused for more than 5 well operations.

Q: What is the maximum pressure and temperature rating available?

A: Standard models have rated working pressures of 5,000 psi and 10,000 psi, with standard temperature ratings of 250°F and 300°F. For HPHT well conditions, we offer custom upgraded designs with a maximum pressure rating of up to 20,000 psi and a temperature rating of up to 500°F (260°C).

Q: Is the packer suitable for H2S and CO2 corrosive environments?

A: Yes. For formations containing H2S, CO2, and other corrosive media, we provide packers manufactured with corrosion-resistant materials including L80-13Cr, Duplex Stainless Steel (2205/2507), and high-nickel alloys. We also use HNBR and FKM sealing elements to ensure long-term reliable performance in corrosive downhole environments.

Q: Is special tooling required to set and retrieve the packer?

A: No special downhole tooling is required. Setting is completed via a simple 1/4 right-hand rotation of the tubing string and slacking off predetermined weight at the target depth. Retrieval is achieved by directly picking up the tubing string, with one-trip retrieval without milling or additional intervention. A detailed operation manual is provided with every shipment, and on-site operational guidance is available upon request.

Q: What casing sizes are available?

A: Our standard models cover the most commonly used casing sizes from 4-1/2" to 9-5/8". We also provide full customization for non-standard casing sizes to match your specific wellbore dimensions.

Q: Can multiple packers be run in series for multi-zone completion?

A: Yes. Our retrievable compression packer can be installed in series with other packers for multi-zone completion and stimulation operations. The stable locking mechanism and bi-directional pressure resistance ensure reliable isolation of each zone, and each packer can be retrieved individually after operations are completed.

Q: What is your production and delivery lead time?

A: For standard models, we maintain inventory for fast delivery within 3-7 working days. For customized models, the production lead time is typically 15-30 working days, depending on customization complexity and order quantity. We support global shipping via sea, air, and express, with full logistics tracking provided.
