Single Slip Composite Bridge Plug | API 11D1 | 10,000 PSI | Easy Drill-Out

1. Single-Slip Anchoring with Zirconia Ceramic Teeth

The plug adopts a high-strength single-slip design with toughened zirconia ceramic slip teeth that firmly embed into the casing wall during setting, providing reliable anchoring without rotation during subsequent drill-out. Compared to multi-slip configurations, the single-slip structure simplifies installation, reduces overall plug length, and distributes anchoring force more uniformly - minimizing casing wall damage while maintaining secure locking performance under differential pressure up to 10,000 PSI (70MPa).

2. High-Performance Composite Material Construction

With the exception of the slip teeth, all structural components are manufactured from high-strength non-metallic composite materials engineered through specialized layer-weaving methods. The composite formulation is tailored to specific working conditions and mechanical performance requirements, delivering excellent chemical resistance, high tensile strength, low permeability, and resistance to downhole corrosion and fatigue. The composite construction also reduces plug weight by up to 60% compared to equivalent cast iron bridge plugs, lowering transportation costs and easing manual handling at the wellsite.

3. Rapid Drill-Out Efficiency

The composite body is specifically engineered for fast, efficient drill-out. A single plug can be drilled out in ≤20 minutes using conventional milling tools and operating parameters (recommended: 60–150 RPM, 5–15 kN weight-on-bit). This is significantly faster than cast iron bridge plugs, which typically require 45–90 minutes per plug. The composite material generates fine, easily circulated debris during milling, reducing the risk of stuck pipe and minimizing cleanout time. Total drill-out and cleanout time is typically reduced by 50–70% compared to cast iron alternatives.

4. Reliable Multi-Layer Sealing Performance

The plug is equipped with a three-element rubber sleeve (upper, middle, and lower sealing elements) and a pressure-adaptive sealing structure that ensures uniform stress distribution across the casing annulus. The seal system provides reliable gas-tight isolation at rated differential pressure of 10,000 PSI (70MPa), with the ability to withstand reverse formation pressure from below. The multi-element design provides redundancy - if one element is damaged during run-in, the remaining elements maintain sealing integrity.

5. Easy Installation with Standard Tool Compatibility

The plug is fully compatible with standard Baker and Owen hydraulic setting tools and uses a ball-drop hydraulic setting method, enabling one-time setting and release with conventional operating procedures. No specialized equipment or operator training is required. The compact single-slip design allows deployment through deviated wellbores and narrow casing restrictions, and the plug is suitable for vertical, horizontal, and deviated well applications across a range of casing sizes.

6. Cost-Effective and Customizable

The lightweight composite material reduces transportation, handling, and downhole operation costs, while the simplified single-slip structure lowers manufacturing and maintenance costs compared to multi-slip or dissolvable alternatives. Custom outer diameters, pressure ratings, temperature ratings, and material formulations are available to meet specific wellbore requirements. The composite bridge plug provides a cost-effective middle ground between low-cost cast iron plugs and premium dissolvable plugs - offering faster drill-out than cast iron at a fraction of the cost of dissolvable technology.

The Single Slip Composite Bridge Plug operates through a reliable hydraulic setting process, followed by zonal isolation service, and finally drill-out removal:

Step 1: Running and Positioning

The bridge plug is connected to a dedicated Baker or Owen hydraulic setting tool and run into the wellbore via wireline, coiled tubing, or jointed pipe to the predetermined target depth.

Step 2: Ball Drop and Hydraulic Setting

A setting ball is dropped from surface and seats in the setting tool, creating pressure differential. Applied hydraulic pressure activates the setting tool's push cylinder, which drives the upper push ring forward. This forces the single slip to expand radially along the cone, and the zirconia ceramic teeth embed firmly into the casing wall to form a secure anchor.

Step 3: Seal Compression

As setting force increases, the cone shears the shear pin and continues moving, compressing the three-layer rubber sleeve (upper, middle, and lower elements). The elastomer expands radially against the casing inner diameter, creating a pressure-adaptive gas-tight seal across the annulus between the bridge plug and casing.

Step 4: Setting Tool Release

After the plug is fully set and anchored, the setting tool releases from the plug and is retrieved to surface. The well is now ready for subsequent operations such as hydraulic fracturing, cementing, or formation testing.

Step 5: Zonal Isolation Service

During operations, the single-slip anchor maintains plug positioning and the multi-layer seal prevents fluid cross-flow between isolated zones, sustaining differential pressure up to 10,000 PSI (70MPa).

Step 6: Drill-Out Removal

After downhole operations are complete, the composite bridge plug is drilled out using conventional milling tools (coiled tubing or jointed pipe). The composite body drills out in ≤20 minutes per plug, generating fine debris that is circulated out of the wellbore, restoring full drift diameter for production or subsequent operations.

Every Single Slip Composite Bridge Plug is manufactured under an ISO 9001:2015 certified quality management system and designed in accordance with API 11D1 specifications for downhole packers and bridge plugs. Our quality assurance process covers the full product lifecycle:

Raw Material Control

Composite material batches are sourced from approved suppliers and accompanied by material test reports (MTR) verifying fiber content, resin system, and mechanical properties. Each batch undergoes tensile strength testing, hardness testing, and chemical resistance verification. Toughened zirconia ceramic slip teeth are inspected for dimensional accuracy and fracture toughness before assembly.

In-Process Manufacturing Control

Composite body components are manufactured using documented layer-weaving and curing processes. Critical dimensions - including outer diameter, seal groove dimensions, slip tooth positioning, and cone angles - are inspected at first-article, in-process, and final inspection stages using calibrated micrometers, bore gauges, and coordinate measuring machines.

Performance Testing

• Hydrostatic Pressure Seal Test: Each plug is assembled and tested at rated differential pressure (10,000 PSI / 70MPa) with zero visible leakage as the pass criterion

• Setting Function Test: Sample plugs from each production lot are set in test casing to verify slip expansion, seal compression, and shear pin release

• Drill-Out Efficiency Test: Representative samples are drilled out to verify ≤20 minute drill-out time and debris characteristics

• Tensile and Compression Testing: Composite material samples tested to verify mechanical properties meet specification

Warranty and Support

We provide a 12-month warranty from the date of shipment against manufacturing defects in materials and workmanship. Our engineering team provides 24-hour online technical support for product selection, running procedures, drill-out parameter optimization, and field troubleshooting.

1. Multi-Stage Hydraulic Fracturing (Plug-and-Perf)

The single slip composite bridge plug is widely used as a zonal isolation barrier in plug-and-perf (PnP) multi-stage fracturing operations for shale gas, tight oil, and low-permeability reservoirs. The plug isolates previously fractured zones, allowing pressure to build and effectively stimulate new reservoir intervals. After all fracturing stages are complete, the plugs are drilled out in a single coiled tubing run - with ≤20 minutes per plug - restoring full bore access for production. The lightweight composite design reduces transportation and handling costs compared to cast iron alternatives.

2. Well Cementing Operations

The plug serves as a temporary flow barrier during primary and remedial cementing operations, ensuring accurate cement placement around the casing annulus without displacement by formation fluids or U-tubing. After cement curing, the composite plug is quickly drilled out to enable well perforation and hydrocarbon production. The rapid drill-out capability minimizes rig time between cementing and completion operations.

3. Temporary Zonal Isolation for Testing and Stimulation

The plug isolates specific wellbore sections for formation testing, acid stimulation, or production logging, preventing fluid cross-flow between different zones and ensuring the accuracy of test results and effectiveness of stimulation treatments. After the operation, the plug is drilled out and the well returns to full production. The single-slip design is particularly suitable for deviated wells where multi-slip plugs may have difficulty setting uniformly.

4. Well Abandonment (P&A) and Suspension

For temporary well suspension or as a component in plug-and-abandonment (P&A) operations, the composite bridge plug provides reliable pressure-rated isolation of hydrocarbon-bearing zones, aquifers, or depleted formations. When used in conjunction with cement plugs and cast iron bridge plugs as part of a multi-barrier abandonment system, the composite plug offers a cost-effective, easily removable intermediate barrier. For permanent abandonment requiring no future access, cast iron or cement plugs are typically specified as the primary permanent barrier.

Q: What is the difference between a composite bridge plug and a cast iron bridge plug?

A: The primary difference is material and drill-out speed. A composite bridge plug uses a high-strength non-metallic composite body that drills out in ≤20 minutes per plug with minimal fine debris, while a cast iron bridge plug is metallic and typically requires 45–90 minutes per plug to drill out, generating larger metal cuttings. Composite plugs are also up to 60% lighter, reducing handling and transportation costs. Cast iron plugs are generally lower in unit cost and may be preferred for permanent abandonment where drill-out speed is less critical.

Q: What is the difference between a composite bridge plug and a dissolvable (soluble) bridge plug?

A: A composite bridge plug requires mechanical drill-out after use (≤20 minutes per plug), while a dissolvable bridge plug degrades completely in wellbore chloride fluids without any intervention. Dissolvable plugs eliminate coiled tubing mill-out entirely but are significantly more expensive. Composite plugs provide a cost-effective middle ground - faster and cleaner drill-out than cast iron, at a fraction of the cost of dissolvable technology. The choice depends on well economics: dissolvable plugs are preferred for extended-reach wells where coiled tubing access is limited, while composite plugs are ideal for standard wells where drill-out cost is manageable.

Q: What certifications does the Single Slip Composite Bridge Plug have?

A: The plug is designed and manufactured to API 11D1 specifications for downhole packers and bridge plugs, and our facility is ISO 9001:2015 certified.

A: Standard sizes include 4½" (114.3mm), 5" (127mm), and 5½" (139.7mm) casing, with corresponding plug outer diameters of 90mm, 98mm, and 105/110mm respectively. Custom outer diameters and specifications for other casing sizes can be manufactured to order.

Q: What is the maximum pressure and temperature rating?

A: The rated differential pressure is 10,000 PSI (70MPa). The plug is suitable for a wide range of downhole temperatures; specific temperature ratings depend on the composite material formulation and elastomer grade selected. Standard formulations cover typical well temperatures up to 150°C (300°F), with high-temperature elastomer options available for hotter wells.

Q: What is the drill-out time and what parameters are recommended?

A: The composite body drills out in ≤20 minutes per plug using conventional milling tools. Recommended drill-out parameters are: rotation speed 60–150 RPM, weight-on-bit 5–15 kN, with sufficient circulation rate to carry fine composite debris out of the hole.
