High-Power Mineral Insulated Heat Tracing for Oil Wells, Customizable Watt Density & Lengths
Engineered for extreme conditions, our High-Power Mineral Insulated Heat Tracing System delivers uncompromising performance in oil well temperature maintenance applications. This robust heating solution features a durable stainless steel sheath and high-density magnesium oxide insulation, providing superior thermal conductivity and corrosion resistance. With customizable watt density (20-60 W/m) and variable lengths, our system ensures precise temperature control in downhole environments where conventional heating methods fail.
Key advantages include:
- ✓ 600°C thermal endurance – withstands oil well operating extremes
- ✓ Uniform heat distribution – eliminates cold spots in well casings
- ✓ Intrinsic safety – mineral insulation prevents short circuits
- ✓ Reduced maintenance – resistant to chemical degradation and physical damage
Technical specifications include:
| Parameter | Standard Range | Custom Options |
| Maximum Exposure Temperature | 600°C | Up to 800°C |
| Voltage Rating | 240V AC | 120-480V AC |
| Sheath Material | 316 Stainless Steel | Inconel 600 |
The concentric conductor design ensures consistent heat flux along the entire length, critical for preventing paraffin deposition and maintaining optimal fluid viscosity. Installation flexibility allows deployment in vertical, horizontal, or coiled tubing configurations without compromising thermal efficiency. Field-proven in shale formations and deepwater wells, our system reduces power consumption by up to 35% compared to conventional skin-effect tracing.
For challenging environments, we offer:
- ▶ Corrosion-resistant alloy sheaths for sour gas wells
- ▶ Explosion-proof terminations for Class I Division 1 areas
- ▶ Continuous monitoring systems with RTD sensors
Optimize your well production with a heating solution that withstands extreme pressures, corrosive fluids, and thermal cycling. Our engineering team provides comprehensive thermal design analysis to ensure precise heat requirements are met without oversizing.

FAQ:
Q: What makes mineral insulated cables suitable for downhole applications?
A: The hermetic stainless steel sheath prevents moisture ingress while magnesium oxide insulation maintains stable dielectric properties even at extreme temperatures encountered in wellbores.
Q: Can the system be installed in existing wells?
A: Yes, our flexible MI cables can be deployed through tubing hangers and attached to production tubing without major modifications.
Q: How are maintenance requirements minimized?
A: The solid construction eliminates moving parts while corrosion-resistant materials prevent degradation from H₂S, CO₂, and brines.
Q: What control systems are compatible?
A: Standard SCR controllers or advanced PLC-based systems with temperature zoning capabilities.
Q: Are custom lengths available for offshore platforms?
A: We manufacture continuous lengths up to 1,500 meters to minimize splices in critical applications.
