Wide Range Bridge Plug | ISO 14310 V0 Zero Leak | 7,500 PSI | 1.610"–5.044" Setting Range | Retrievable or Drillable

The Wide Range Bridge Plug (WRBP) is a specialized downhole isolation tool designed to seal off wellbore sections at a chosen depth, preventing fluid flow between upper and lower zones during well testing, stimulation, cementing, workover, abandonment, or temporary shutdown operations. Its defining feature is an ultra-wide setting range - from 1.610" to 5.044" with custom configurations available up to 20" - allowing a single plug model to adapt to a broad spectrum of casing sizes and weights, eliminating the need to stock multiple single-size bridge plug types and significantly reducing tool inventory, logistics complexity, and operational costs for service companies and operators. Validated to ISO 14310 V0 (the highest zero-leakage qualification level) and API Spec 11D1 standards, the WRBP delivers a maximum working pressure up to 7,500 PSI with standard temperature resistance up to 300°F (149°C), and high-temperature models available up to 500°F (260°C) for HPHT applications. The plug features a three-piece elastomer packing element system with metal backup rings that provide a reliable, pressure-tight seal even in high-temperature and high-pressure environments, while the ratchet lock ring stores and maintains setting force to ensure consistent sealing pressure and prevent premature release during pressure fluctuations. The case-hardened one-piece slips, ratchet, and mandrel components feature a hardened, non-corrosive finish for long service life in corrosive fluid environments. An integrated pressure equalization bypass valve automatically equalizes pressure above and below the plug before retrieval - closing during setting to maintain the seal and opening during retrieval to facilitate fluid bypass - minimizing the risk of premature release from trapped pressure and ensuring safe, efficient tool recovery. The WRBP can be set hydraulically using standard rig pumps (no dedicated high-pressure pumps required) or via wireline with Go, Baker, or Gearhart setting tools, providing deployment flexibility across different rig capabilities. Retrieval is by mechanical right-hand rotation with a standard retrieval tool, or the plug can be optionally drilled out for permanent isolation applications. The compact design with casing-drift outer dimensions allows smooth passage through wellbore restrictions, and the plug is compatible with all casing hardness types in vertical, horizontal, and high-angle wells. Whether for well abandonment, cementing, zone isolation, well testing, temporary well shutdowns for equipment maintenance, shale gas multistage fracturing, or geothermal well operations, the WRBP provides a secure, ISO 14310 V0-qualified pressure-tight seal that meets the rigorous demands of modern oil, gas, and geothermal operations - with deployment and retrieval typically 20–30% faster than standard bridge plugs.

1. Ultra-Wide Setting Range (1.610" – 5.044")

Compatible with casing sizes from 1.610" to 5.044" (customizable for larger sizes up to 20"), the WRBP adapts to diverse wellbore configurations with a single plug model - reducing the need for multiple tool inventories, simplifying logistics and warehouse management, and lowering capital and operational costs for service companies. The wide-range design is particularly valuable for workover and service rigs that encounter varied casing sizes across a field, eliminating the need to mobilize different plug sizes for each well.

2. Superior Sealing with ISO 14310 V0 Zero-Leak Qualification

Equipped with a three-piece elastomer packing element and metal backup rings, the plug delivers a reliable, pressure-tight seal even in high-temperature and high-pressure (HPHT) environments - validated to ISO 14310 V0 (zero leakage) standards, the highest qualification level for downhole isolation tools. The ratchet lock ring stores and maintains setting force, ensuring consistent sealing pressure during pressure reversals and preventing premature release. Maximum working pressure up to 7,500 PSI (51.7 MPa), with standard temperature rating to 300°F (149°C) and high-temperature models to 500°F (260°C).

3. Durable & Corrosion-Resistant Construction

Slip, ratchet, and mandrel components feature a hardened, non-corrosive finish, ensuring long service life in harsh downhole conditions including corrosive fluids (H2S, CO2, brine) and high temperatures, and minimizing wear during deployment and retrieval. The case-hardened one-piece slips provide secure casing engagement across the full setting range, and the corrosion-resistant alloy construction maintains structural integrity in sour service and acidic environments.

4. Easy Deployment & Retrieval (20–30% Faster)

The compact design with casing-drift outer dimensions allows smooth passage through wellbore restrictions, including nipple profiles, restrictions, and damaged casing sections. The plug can be hydraulically set using standard rig pumps - no dedicated high-pressure pumps required - reducing equipment needs and setup time. Alternatively, it can be set via wireline with Go, Baker, or Gearhart setting tools for wireline-deployed operations. Retrieval is by mechanical right-hand rotation with a standard retrieval tool. The user-friendly design typically reduces deployment and retrieval operation time by 20–30% compared to standard bridge plugs, reducing rig time and labor costs.

5. Integrated Pressure Equalization Bypass Valve

Features an integrated bypass valve that automatically equalizes pressure above and below the plug before retrieval - minimizing the risk of premature release caused by trapped differential pressure and ensuring safe, efficient tool recovery. The valve closes during setting to maintain the pressure seal, and opens during retrieval to facilitate fluid bypass, allowing the plug to be retrieved without swabbing or pressure surging that could destabilize the wellbore or damage equipment. This is a critical safety feature for retrievable bridge plugs in high-pressure wells.

6. Drillable Design (Optional) for Permanent Isolation

Case-hardened one-piece slips and drillable components can be easily drilled out with PDC bits if permanent isolation is required, providing flexibility for both temporary (retrievable) and permanent (drillable) well operations from the same base tool design. The drill-out produces small, easily circulated cuttings with minimal casing damage. This dual-configuration capability allows operators to select retrieval or drill-out based on well objectives without changing tool type.

The Wide Range Bridge Plug operates in four phases - deployment, setting, isolation, and retrieval or drill-out:

Phase 1: Deployment

The WRBP is connected to the setting tool - either a hydraulic setting assembly run on tubing/work string, or a wireline setting tool (Go, Baker, or Gearhart compatible) - and run into the wellbore to the target setting depth. The compact casing-drift OD design allows the plug to pass through wellbore restrictions, nipple profiles, and casing damage without hang-up. The slips are retracted and the packing element is uncompressed during run-in, and the pressure equalization bypass valve is in the closed position. The wide-range design allows the same plug model to be used across multiple casing sizes within the 1.610"–5.044" range.

Phase 2: Setting

Once on depth, the plug is set by one of two methods: • Hydraulic Setting: Pressure is applied through the work string using standard rig pumps (no high-pressure pumps required). The pressure actuates the setting mechanism, driving the slip cone forward to expand the case-hardened one-piece slips outward against the casing wall, and compressing the three-piece packing element to form a pressure-tight seal. The metal backup rings support the packing element to prevent extrusion. • Wireline Setting: A wireline setting tool (Go, Baker, or Gearhart) is fired to generate the setting force, expanding the slips and compressing the packing element. In both methods, the ratchet lock ring engages during setting, mechanically storing and locking the setting force so that the seal is maintained even after the setting force is removed. The setting tool then releases and is retrieved to surface.

Phase 3: Isolation

Once set, the case-hardened slips and compressed three-piece packing element create a reliable pressure barrier qualified to ISO 14310 V0 (zero leakage), containing differential pressure up to 7,500 PSI from either direction. The ratchet lock ring maintains setting force during pressure fluctuations and reversals. The plug remains in place for the intended operation - well testing, stimulation, cementing, workover, abandonment, or temporary shutdown. The pressure equalization valve remains closed during the isolation period, maintaining the pressure seal.

Phase 4: Retrieval or Drill-Out

For retrievable applications: a standard mechanical retrieval tool is run on tubing, wireline, or coiled tubing and engages the plug. The retrieval operation first opens the integrated pressure equalization bypass valve, equalizing pressure above and below the plug to eliminate trapped pressure. Right-hand rotation is then applied to release the ratchet lock and slips, and the plug is pulled intact to surface. For permanent applications: when isolation is no longer required, the case-hardened slips and drillable components are milled out using PDC bits on coiled tubing or drill pipe, producing small, easily circulated cuttings.

Warranty

12-month warranty from date of shipment against manufacturing defects, with 24-hour technical support for setting procedure, retrieval optimization, and troubleshooting.

1. Temporary Zone Isolation

Isolate specific well zones for stimulation, acidizing, fracturing, or workover operations, ensuring operations are carried out safely without affecting other zones. The wide setting range allows the same plug to be used across different casing sizes in a multi-zone well, and the retrievable design allows recovery after the operation - eliminating drill-out costs for temporary applications. The ISO 14310 V0 zero-leak qualification ensures no fluid cross-flow during critical operations.

2. Well Abandonment & Cementing

Provide permanent isolation for well abandonment (P&A) or cementing operations, ensuring long-term wellbore integrity and environmental compliance. The optional drillable configuration allows the plug to be milled out if future re-entry is required, and the wide size range covers both production and intermediate casing abandonment. The ISO 14310 V0 qualification meets regulatory P&A requirements for zero leakage.

3. Well Testing & Pressure Testing

Seal off well sections to conduct pressure testing of production tubing, wellheads, BOPs, or completion equipment. The hydraulic setting method using standard rig pumps is ideal for well testing operations where wireline equipment may not be available, and the pressure equalization valve ensures safe retrieval after testing without pressure surges.

4. Temporary Well Shutdown

Securely shut in wells for completion equipment servicing, Christmas tree maintenance, BOP repair, or emergency repairs, minimizing downtime and operational risks. The retrievable design allows the well to be returned to service quickly after maintenance without drill-out, and the compact drift design allows deployment through existing completion equipment.

5. Shale Gas & Geothermal Well Operations

Ideal for multi-zone fracturing, zone isolation, and acidizing operations in shale gas wells, supporting efficient reservoir development with fast deployment and retrieval. Also suitable for geothermal well operations, where high temperatures (up to 500°F with HT models) and corrosive geothermal fluids require durable, corrosion-resistant isolation tools. The wide setting range is particularly valuable in geothermal wells where casing programs may vary from standard oilfield designs.

Q: What does "wide range" mean and how does it reduce my costs?

A: The Wide Range Bridge Plug has an ultra-wide setting range of 1.610" to 5.044" (customizable up to 20"), meaning a single plug model can be used across multiple casing sizes within that range - unlike conventional bridge plugs where each casing size requires a dedicated plug model. This reduces the number of plug sizes you need to stock, simplifies logistics and inventory management, and lowers capital costs for service companies and operators that work across fields with varied casing sizes.

Q: What is ISO 14310 V0 and why is it important?

A: ISO 14310 is the international standard for qualifying downhole isolation tools (packers and bridge plugs). V0 is the highest qualification level - it requires zero visible gas leakage at rated pressure and temperature, verified through rigorous testing including pressure reversals and temperature cycling. Most bridge plugs on the market are qualified to V3 (allowing some leakage) or lower. Our WRBP's ISO 14310 V0 qualification means it provides a zero-leak seal, which is critical for well abandonment, sour gas wells, underground gas storage, and regulatory-compliant operations where any leakage is unacceptable.

Q: How is the plug set and what equipment is needed?

A: The WRBP can be set by two methods: (1) Hydraulic setting using standard rig pumps - no dedicated high-pressure pumps required - applied through the work string; or (2) Wireline setting using Go, Baker, or Gearhart wireline setting tools. Both methods expand the slips and compress the packing element to set the plug. The choice depends on available rig equipment and operational preference. Retrieval is by mechanical right-hand rotation with a standard retrieval tool.

Q: What is the pressure equalization valve and why is it important?

A: The integrated pressure equalization bypass valve is a safety feature that automatically equalizes pressure above and below the plug before retrieval. It closes during setting to maintain the pressure seal, and opens during retrieval to allow fluid bypass - eliminating the risk of trapped differential pressure that could cause premature release, swabbing, or pressure surges during retrieval. This is particularly important in high-pressure wells where trapped pressure can make retrieval dangerous or cause well control issues.

Q: What are the pressure and temperature ratings?

A: Maximum working pressure is up to 7,500 PSI (51.7 MPa), qualified to ISO 14310 V0. Standard temperature rating is up to 300°F (149°C), with high-temperature models available up to 500°F (260°C) for HPHT and geothermal applications. Exact pressure ratings may vary slightly by casing size within the setting range - contact our engineering team for size-specific ratings.

Q: What is the MOQ, delivery time, and payment method?

A: The MOQ is 1 unit for standard models, with flexible MOQs for custom orders. Standard models ship within 7–10 working days; custom orders require 15–25 working days depending on complexity. We ship from Shanghai or Ningbo port. Payment terms include T/T (30% deposit, 70% before shipment), L/C at sight, and Western Union. Sample testing units available for qualified customers.

Q: Can the WRBP be used in horizontal and high-angle wells?

A: Yes. The WRBP is designed for use in vertical, horizontal, and high-angle wells, with a compact casing-drift OD design that ensures smooth deployment through restricted and deviated wellbores. The hydraulic setting method is particularly reliable in highly deviated wells where wireline setting may be less consistent, and the pressure equalization valve ensures safe retrieval regardless of well trajectory.
