Extended Reach Dissolvable Bridge Plug

Extended Reach Dissolvable Bridge Plug: Advanced Isolation for Ultra-Long Laterals

When you're completing extended-reach wells beyond 3,000 meters, traditional plugs create serious intervention challenges. The Extended Reach Dissolvable Bridge Plug from Shaanxi Hagrien Energy Technology solves this problem with engineered magnesium alloys that vanish completely after use. Our plugs deliver reliable pressure ratings up to 15,000 psi (105 MPa), operate across temperatures from 40°C to 150°C, and offer customizable dissolution timelines from 24 hours to 14 days. With extruded rods up to Ø300mm and CNAS-accredited HPHT testing, we provide full traceability and predictable lead times of 2-4 weeks for standard configurations.

What Makes Our Dissolvable Bridge Plugs Different

You need tools that work the first time in challenging environments. That's why our approach starts with material science.

Engineered Alloy Performance

We don't just supply off-the-shelf materials. Your well conditions determine our alloy formulation. High-purity magnesium matrix (99.9% Mg) forms the foundation. Then we adjust composition based on your specific salinity, temperature profile, and required dissolution window.

This means you get predictable degradation behavior. No surprises downhole.

Large-Diameter Manufacturing Control

Our closed-loop manufacturing system produces extruded billets up to Ø300mm diameter. Uniform microstructure throughout every piece. Dimensional stability you can machine with confidence.

This capability reduces your scrap rates and speeds up prototype-to-production cycles.

Technical Specifications

Why Extended Reach Wells Need This Solution

Traditional milling operations hit a wall in ultra-long laterals. Literally.

The Friction Problem

Coiled tubing loses mechanical effectiveness beyond certain lateral lengths. When you can't reach the toe plugs, you face difficult choices. Leave hydrocarbons behind. Or risk expensive fishing operations.

The Extended Reach Dissolvable Bridge Plug eliminates this constraint entirely. Deploy your full stage count. Complete your fracturing program. Then let chemistry do the cleanup work.

Zero-Residue Completions

Dissolved magnesium becomes ionic solution in your wellbore fluids. It flows back to surface as liquid. No solid debris to create bridge-off risks in low-energy reservoirs.

Your production tubing stays clear. Flow assurance improves from day one.

Key Advantages for Your Operations

1. Suitable for Ultra-Long Lateral Programs

We've engineered these plugs specifically for wells exceeding 3,000 meters. Compact design navigates casing doglegs smoothly. High strength-to-weight ratio reduces running risks during high-speed RIH operations.

2. Temporary Isolation with Controlled Degradation

You define the dissolution window based on your completion schedule. Need 48 hours for fracturing? Or 7 days for complex multi-well pad operations? We adjust alloy chemistry to match your timeline exactly.

3. Reduced Post-Frac Cleanout Complexity

Eliminate 48-72 hours of milling time per well. Cut coiled tubing mobilization costs. Reduce HSE exposure from mechanical intervention. Your breakeven timeline shortens significantly.

4. Service Company Qualification Ready

We understand your procurement requirements. Full verification documentation packages support supplier qualification processes. CNAS-accredited HPHT testing validates every performance claim. ISO 9001/14001/45001 certifications ensure manufacturing consistency.

5. Backed by Integrated Manufacturing Capability

From alloy melting to final CNC machining, we control every critical process step. This vertical integration means you get repeatable quality batch after batch. No surprises. No excuses.

Application Scenarios

High-Density Multi-Stage Fracturing

When you're pumping 50+ stages in a single lateral, composite debris volume becomes a serious concern. Each traditional plug leaves material in the wellbore. Accumulation creates bridge-off risk.

Dissolvable plugs solve this elegantly. Zero solid residue means zero accumulation. Your flow path stays clear regardless of stage count.

Re-Fracturing Aged Wells

Older casing can't always handle the vibration and torque of aggressive milling. Dissolvable isolation protects compromised infrastructure. You stimulate the formation without stressing the casing.

This extends field life and unlocks stranded reserves safely.

Shale Gas Completions Beyond 5,000 Meters

These ultra-extended wells represent the frontier of unconventional development. Friction limits make traditional intervention nearly impossible.

Our Extended Reach Dissolvable Bridge Plug turn impossibility into routine operations. Deploy your full completion design. Access the entire lateral's productive potential.

Quality Control You Can Verify

Material Homogeneity Testing

Every batch undergoes ultrasonic inspection and X-ray diffraction analysis. We're checking for impurities that could cause premature failure. Uniform microstructure means predictable mechanical properties.

HPHT Hold Testing

We simulate your worst-case downhole conditions in our CNAS-accredited laboratory. Maximum rated pressure. Peak temperature. Extended duration. Zero leakage across elastomer seals. That's our standard before any plug ships.

Controlled Degradation Verification

Weight-loss testing in specific brine concentrations validates dissolution curves. Electrochemical analysis confirms galvanic behavior matches design parameters. You get predictable performance based on real data, not marketing claims.

Full Traceability

From raw alloy melt through final inspection, we document every process step. Heat maps. Batch tracking. Dimensional inspection records. When your procurement team needs audit support, we're ready.

Frequently Asked Questions

Q: How does water salinity affect dissolution of the product?

A: Higher chloride concentrations accelerate the galvanic reaction naturally. But we've developed proprietary coating technology for low-salinity environments. Even fresh water wells get consistent degradation performance.

Q: Is there risk of pre-setting during high-speed run-in-hole?

A: No. Our design includes high-strength anti-preset shear rings. They exceed hydraulic drag forces encountered in extended-reach laterals. You can run at optimal speeds without setting concerns.

Q: What if well temperature is lower than expected?

A: We provide low-temperature activators that ensure consistent degradation even below 50°C. Temperature variations won't derail your completion schedule.

Q: Will dissolved material damage reservoir formation?

A: Not at all. Magnesium ions and hydrolyzed polymers dissolve into brine. They produce back as liquid. Zero solid residue means zero formation damage. Your permeability stays intact.

Q: Can these plugs maintain 15,000 psi for extended periods?

A: Yes. We test every design under ISO 14310 V3 standards. Sustained pressure hold capability is validated before commercial release. Your isolation integrity stays secure throughout fracturing operations.

Q: How do I specify the right dissolution timeline?

A: Share your wellbore fluid chemistry, temperature profile, and operational timeline with us. We'll recommend alloy formulations that match your needs. Engineering support is included with every order.
