Controlled Degradation Frac Plug Assembly

Controlled Degradation Frac Plug Assembly 

The Controlled Degradation Frac Plug Assembly from Shaanxi Hagrien Energy Technology delivers proven downhole isolation without mill-out intervention. Built from precision-engineered magnesium alloys, our assembly withstands differential pressures up to 15,000 psi across temperature ranges from 70°F to 350°F. Leveraging our closed-loop manufacturing system—from alloy melting through precision machining—we produce large-diameter components up to Ø300 mm with uniform microstructure and dimensional stability. Each unit comes with full COA/COC documentation and batch traceability, ensuring audit-ready compliance. Standard lead times run 2–4 weeks, with customized solutions delivered in 4–8 weeks to match your completion schedules.

What Makes Our Solution Different

Engineered Material Science

Our Controlled Degradation Frac Plug Assembly uses proprietary magnesium alloy formulations tailored to your wellbore conditions. You get predictable dissolution rates adjusted for temperature, salinity, and fluid chemistry. This means reliable isolation during pumping, followed by complete degradation when you need flow-back.

Each alloy batch undergoes strict metallurgical control. We balance mechanical strength with controlled corrosion behavior. Your plugs won't fail prematurely during fracturing operations, yet they dissolve efficiently post-treatment.

Manufacturing Precision You Can Trust

We control every production step in-house:

• Alloy melting with real-time composition monitoring
• Extrusion for uniform grain structure
• CNC machining to tight tolerances
• CNAS-accredited testing for pressure and dissolution verification

This vertical integration eliminates third-party risks. You receive components with consistent quality, batch after batch.

Performance Under Pressure

Your operations demand tools that work flawlessly downhole. Our assemblies deliver:

• High anchoring force through precision-machined slips
• Zero bypass sealing during high-pressure pumping
• Geometric stability that prevents premature structural failure
• Temperature resistance maintaining integrity throughout frac stages

We validate each design through hydrostatic pressure testing per API 11D1 standards. Our HTHP laboratory simulates real downhole conditions before any product reaches your wellsite.

Technical Specifications

Where This Technology Excels

Extended Reach Laterals

In horizontal wells exceeding 10,000 feet, traditional milling faces severe challenges. Coiled tubing experiences helical buckling. Motors lose torque. Debris management becomes a nightmare.

Our dissolvable assembly eliminates these issues entirely. Set your plugs, pump your stages, then let chemistry do the work. The entire lateral opens to flow without mechanical intervention. You save rig time and reduce completion costs significantly.

High-Pressure, High-Temperature Environments

Deepwater completions demand absolute reliability. Intervention costs can exceed $1 million per day. You cannot afford tool failures or stuck mill assemblies.

The Controlled Degradation Frac Plug Assembly provides secure zonal isolation during stimulation. After your frac stages, it degrades autonomously. You move straight to production without subsea intervention, protecting your project economics.

Re-Fracturing Operations

When restimulating existing wells, internal diameter restrictions limit tool options. Permanent plugs create flow bottlenecks. Mill-out operations risk damaging existing completions.

Our slim-profile degradable design fits within restricted casing strings. It isolates zones during treatment, then disappears completely. You get effective stimulation without permanent flow restriction.

Multi-Stage Completions

Modern unconventional wells require 20, 30, even 50+ frac stages. Milling each plug adds days to completion schedules. Equipment failures compound delays exponentially.

Switching to dissolvable technology transforms your completion workflow. Pump all stages continuously. The plugs degrade on schedule, clearing the wellbore without intervention. Your well reaches production weeks earlier.

How We Ensure Consistent Quality

Material Verification

Every alloy batch undergoes Optical Emission Spectroscopy (OES) analysis. We verify composition against design specifications before machining begins. This prevents "hot spots" that cause unpredictable degradation behavior.

Dissolution Testing

We don't guess at degradation rates. Material coupons from each production run undergo laboratory testing in controlled brine solutions. You receive precise degradation curves for your specific wellbore conditions.

Dimensional Accuracy

CMM (Coordinate Measuring Machine) inspection ensures slip tolerances and seal geometries meet exact specifications. This guarantees bypass-free isolation during your frac operations.

Pressure Validation

Each assembly design passes hydrostatic testing at rated differential pressures. We simulate downhole temperatures in our HTHP laboratory. Only proven designs reach field deployment.

Full Traceability

Every component carries complete documentation:

• Material certificates (COA/COC)
• Inspection records
• Batch tracking numbers
• Safety data sheets (SDS)

This documentation package supports your supplier qualification and audit requirements.

Frequently Asked Questions

Q: How do you control dissolution timing?

A: We engineer alloy composition and surface treatment based on your wellbore parameters—temperature, salinity, and fluid chemistry. Higher chloride concentrations accelerate galvanic reactions in magnesium-based assemblies. For low-salinity wells, we formulate specialized alloys or recommend activator fluids. This gives you predictable degradation windows aligned with your completion schedule.

Q: Will plugs dissolve during the frac job?

A: No. We design an "incubation period" where surface coatings or material mass resist significant degradation for 24–72 hours. This exceeds typical frac stage durations. You get full isolation performance throughout pumping operations, with degradation beginning only after treatment completion.

Q: What happens in low-temperature wells?

A: We offer specialized low-temperature alloy formulations for wells below 100°F. These materials maintain efficient reaction rates in cooler environments. Share your wellbore conditions during the RFQ process, and we'll specify the appropriate material system.

Q: Can I use these in wells with minimal salinity?

A: Yes. For low-salinity environments, we recommend our modified alloy systems or coordinated activator fluid programs. During engineering discussions, we'll review your water chemistry and recommend the optimal material configuration.

Q: What about the slips and buttons after degradation?

A: The main magnesium alloy body dissolves into micro-particulates that flow to surface with produced fluids. We design any high-strength ceramic inserts to be small enough for fluid transport or settlement in the rat hole. They won't obstruct production or damage downstream equipment.

Q: Do you support custom sizes?

A: Absolutely. Our extrusion capability reaches Ø300 mm, and our precision machining handles complex geometries. Provide your casing dimensions and operating conditions. We'll engineer a solution that fits your specific wellbore requirements with a 4–8 week custom lead time.

Q: How do I verify quality before shipment?

A: We provide complete documentation packages including material certificates, dimensional inspection reports, dissolution test data, and pressure validation results. We also support Factory Acceptance Testing (FAT) at our facility if your procurement process requires witnessed verification.
