Hydraulic Set Dissolvable Bridge Plug

Hydraulic Set Dissolvable Bridge Plug - Engineered Isolation for Modern Well Completions

Shaanxi Hagrien Energy Technology Co., Ltd. delivers enterprise-grade Hydraulic Set Dissolvable Bridge Plug solutions built on fully integrated manufacturing—from alloy melting to precision machining. Our plugs achieve pressure ratings up to 10,000–15,000 psi with temperature stability from 80°F to 350°F. Constructed from engineered magnesium alloys (extruded up to Ø300 mm), each unit features adjustable dissolution rates tailored to your fluid chemistry and bottomhole temperature. ISO 9001 certified production ensures dimensional accuracy within ±0.001", while CNAS-accredited laboratory validation guarantees repeatable performance. Standard lead time: 2–4 weeks with full COA/COC documentation and batch traceability.

What Makes Our Dissolvable Bridge Plug Different

When you're planning multi-stage fracturing operations, traditional plugs create bottlenecks. You spend 24–72 hours milling out each stage, accumulate metallic debris, and tie up coiled tubing crews in extended-reach laterals.

Our solution changes that workflow entirely.

The Hydraulic Set Dissolvable Bridge Plug activates through tubing pressure alone. No wireline. No explosives. You pump pressure, internal pistons engage, and the plug anchors securely in your casing—whether it's 5.5-inch 20# or specialized P110 configurations.

Then the magic happens: controlled dissolution begins after fracturing completes. The magnesium alloy structure breaks down into microscopic particles that flow naturally to surface with produced fluids. You get full-bore access without milling.

How It Solves Real Wellsite Challenges

For Unconventional Shale Operations

Running 50+ stage completions? Traditional mill-out adds weeks to your Time-to-First-Oil. Our plugs eliminate that delay entirely. Set your isolation barrier hydraulically, complete your frac, and let chemistry handle cleanup while you move to production.

In Extended Reach Drilling

Ultra-long horizontals push coiled tubing past its mechanical limits. Helical buckling means you can't reliably reach total depth for mill-out. Since our plugs dissolve in wellbore fluids, you avoid that limitation completely.

Offshore and Remote HPHT Wells

Limited deck space and personnel constraints make milling operations expensive and risky. By removing the need for mechanical intervention, you reduce equipment footprint and crew exposure in high-pressure environments.

Technical Specifications That Matter

Why Material Engineering Matters

Not all magnesium alloys perform the same downhole. Your well conditions—temperature, salinity, pH levels, chloride concentration—directly affect dissolution timing.

We design alloy systems around your specific parameters. Higher temperatures accelerate breakdown. Acidic fluids trigger faster reactions. Protective coatings delay degradation until fracturing completes.

This isn't off-the-shelf material. It's application-engineered metallurgy.

Our closed-loop manufacturing controls every variable: alloy formulation, extrusion parameters, heat treatment cycles, surface finishing. That consistency means predictable performance across your entire well program.

From Raw Material to Verified Product

Step 1: Material Composition Analysis

X-ray diffraction (XRD) verifies the precise alloy blend before machining begins. Wrong composition means unpredictable dissolution.

Step 2: Hydrostatic Pressure Testing

We simulate maximum rated downhole conditions in our CNAS-accredited HTHP laboratory. Every Hydraulic Set Dissolvable Bridge Plug proves it can hold pressure at temperature before shipment.

Step 3: Shear Calibration

Shear screws must release at your exact calculated pressure. We test and document calibration to ensure hydraulic setting happens when you expect it.

Step 4: Dissolution Rate Mapping

Samples go into synthesized wellbore fluids matching your completion design. We map degradation curves against time and temperature, so you know exactly when full-bore access returns.

Step 5: Dimensional Verification

High-precision NOGO gauges confirm compatibility with your casing weight and grade. A plug that doesn't fit properly won't seal reliably.

Quality You Can Audit

Supplier qualification shouldn't feel like guesswork. Our verification-first approach gives you:

• ISO 9001/14001/45001 certified processes
• Full documentation packages with every shipment
• Batch traceability linking material origin to final inspection
• CNAS-accredited test data you can submit for regulatory approval

When auditors arrive or your operations team needs proof of performance, you'll have the records ready.

Customization for Your Well Design

Standard products work for conventional applications. Complex wells need tailored solutions.

We support drawing-based production and prototype development. Share your casing specs, fluid chemistry data, and temperature profile. Our engineering team will co-design the material and structural configuration to match.

Need faster dissolution in low-temperature wells? We'll adjust the alloy composition and recommend a KCl flush protocol.

Operating in extreme HPHT offshore zones? We'll optimize the protective coating system and anchor design for your pressure regime.

From prototype validation to scaled production, you get the same material consistency and dimensional accuracy.

Frequently Asked Questions

Q: What triggers dissolution in the product?

A: Contact with electrolytes in wellbore fluids—like KCl or NaCl brines—initiates the reaction. Higher bottomhole temperatures and acidity accelerate the process. The protective coating prevents premature degradation during fracturing operations.

Q: Can you use these plugs in low-temperature wells?

A: Yes. We formulate specific low-temperature alloys and recommend customized brine flush sequences to ensure timely degradation even when BHT stays below 120°F.

Q: How does hydraulic setting differ from wireline methods?

A: The plug converts tubing or casing pressure into mechanical setting force using internal piston areas. You control activation from surface without running separate setting tools or explosive charges. It simplifies logistics and reduces downhole complexity.

Q: Is there risk the plug dissolves too early?

A: No. The protective coating withstands initial fracturing fluids and high pump rates. Dissolution begins only after the well stabilizes at bottomhole temperature and the coating degrades naturally.

Q: Will residue damage production equipment?

A: The plug breaks down into fine, silt-like particles smaller than typical formation fines. These flow to surface with produced fluids and pass through separators without harming valves, chokes, or pumps.

Q: How long does complete dissolution take?

A: It depends on your well conditions. In 200°F brines with 10% salinity, typical dissolution completes in 5–14 days. We provide dissolution curves based on your specific fluid chemistry and temperature data.

Q: What documentation do you provide for regulatory compliance?

A: Every shipment includes Certificate of Analysis (COA), Certificate of Conformance (COC), and Safety Data Sheets (SDS). Batch traceability records link each plug to material origin, process parameters, and inspection results.
