1. Company Positioning & Customer Awareness 

HAGRIEN — Professional Manufacturer of Dissolvable Magnesium Alloy Downhole Tools

HAGRIEN is a specialized manufacturer with full closed-loop capability in dissolvable magnesium alloy materials and precision downhole tools for the oil & gas industry. We control every stage: in-house alloy formulation, large-diameter extrusion (up to Ø300 mm), precision CNC machining, assembly, and CNAS-accredited HTHP laboratory testing. This positions us as a reliable OEM/ODM partner for operators and service companies seeking high-performance, traceable, and now visualizable zonal isolation solutions.

The Customer Challenge: Operating in the Dark

In today's multistage fracturing operations — especially in shale, tight gas/oil, HPHT, extended-reach, and increasingly digital/smart wells — operators face critical uncertainties:

• Is the bridge plug correctly set and sealed before pumping? (Risk of screen-out or poor isolation)

• When exactly will it dissolve? Too early = loss of isolation; too late = delayed production or stuck operations.

• How to verify dissolution progress without extra costly logging runs that increase NPT?

• How to meet increasingly strict regulatory traceability, environmental reporting, and supplier qualification requirements?

• For fiber-optic (DAS/DTS) equipped wells: How to leverage existing monitoring infrastructure for plug data?

Our Solution: Visualizable Dissolvable Magnesium Alloy Bridge Plug

The Visualizable Dissolvable Magnesium Alloy Bridge Plug is the next evolution of HAGRIEN's proven controlled-dissolution platform. It transforms operations from “blind” to “visible, measurable, and optimizable” by integrating three breakthrough capabilities while fully retaining all core advantages (no milling, full-bore restoration, eco-friendly dissolution, high-pressure integrity).

Core Differentiators (Unique Selling Points)

• Embedded Visualization & Traceability Marker — The white component visible in actual product photos is the primary visualization point. It provides visual, magnetic, or scannable identification for placement confirmation and full digital passport linkage (batch, lab data, simulation results).

• DAS/DTS Fiber-Optic & Logging Compatibility — Seamless integration with permanent or temporary fiber-optic monitoring systems and electromagnetic logging tools for real-time or post-job verification of position, sealing, and dissolution status.

• Predictive Dissolution Visualization Dashboard — Well-specific simulation software supplied with every order. Visualize exact dissolution timeline, particle behavior, and risk scenarios before running in hole. Enables data-driven frac design optimization.

• Full Retention of Proven Performance — >400 MPa tensile strength, 10,000–15,000 psi pressure rating, tunable dissolution 24h to several weeks, 6–12h safe deployment coating, complete dissolution into fine non-toxic particles — zero milling, zero debris, full-bore production path.

• Regulatory & Digital Oilfield Ready — Complete batch traceability, CNAS lab reports, and digital passport simplify compliance, audits, tenders, and supplier qualification. Future-proof for smart wells and AI/ML optimization initiatives.

2. Detailed Product Information & Specifications 

Product Overview

The Visualizable Dissolvable Magnesium Alloy Bridge Plug is engineered for multistage fracturing zonal isolation in cased-hole completions. It provides reliable high-pressure sealing during stimulation and then fully dissolves on a predictable schedule, restoring full-bore access without any milling or cleanout intervention. The addition of embedded traceable markers and monitoring compatibility makes it the ideal choice for modern digital oilfield operations where data visibility and operational certainty are paramount.

4. FAQS

Q1: How can I confirm the plug is correctly set without extra logging runs that increase cost and NPT?

A1: The Visualizable version features embedded traceable markers (visual/magnetic/scannable — the white component) that are compatible with standard logging tools, DAS/DTS fiber-optic systems, and select downhole cameras. You can verify placement and sealing integrity with minimal or no additional runs.

Q2: Can I monitor dissolution progress in real time or after the fracturing job?

A2: Yes. The plug is designed for seamless integration with permanent or temporary fiber-optic monitoring (DAS/DTS). Combined with our predictive visualization dashboard, you can observe dissolution behavior and wellbore condition without guesswork.

Q3: Will the visualization features affect mechanical strength or dissolution performance?

A3: No. The embedded markers and digital enhancements are integrated without compromising the proven >400 MPa tensile strength or controlled dissolution chemistry. All core performance remains identical to our standard dissolvable plugs.

Q4: My well already has fiber-optic cable installed. Is this plug compatible?

A4: Absolutely. It is specifically engineered for fiber-optic equipped wells and smart completions, enabling real-time or post-job data collection on plug position and dissolution status via the traceable marker.

Q5: How does this help with regulatory compliance, audits, and supplier qualification?

A5: Every plug comes with a complete digital passport linked to batch records, CNAS lab data, and dissolution simulation results. This greatly simplifies traceability, environmental reporting, and tender/qualification processes.

Q6: Dissolution timing is critical. What if it dissolves too fast or too slow?

A6: Our predictive dissolution visualization dashboard allows you to simulate and visualize the exact dissolution timeline based on your well’s temperature, salinity, and fluid chemistry before running in hole. We also offer custom alloy tuning for precise control.

Q7: Does it really eliminate milling and cleanout operations in all cases?

A7: Yes. Like our standard plugs, it fully dissolves into fine, flowable, non-toxic particles that are carried out with production fluids, restoring full-bore access with zero debris and no coiled tubing intervention.

Q8: Can you customize both dissolution rate and visualization features for my specific well conditions?

A8: Yes. HAGRIEN provides full engineering support for alloy customization and well-specific simulation dashboard configuration based on your temperature, salinity, and monitoring system requirements.
