Can Electromagnetic Technology Replace Chemical Wax Inhibitors in Offshore Oil Production?
Yes—And It’s Already Working on Shengli Oilfield’s Offshore Platform.
Offshore oil wells in the Shengli Oilfield face a persistent challenge: high-wax crude oil (wax content up to 20.8%) causes rapid deposition in tubing and flowlines, leading to increased back pressure, frequent hot washes, and costly workovers. Traditionally, operators relied on daily chemical inhibitors and thermal cleaning every 15–120 days—costly, labor-intensive, and environmentally taxing.
But what if wax prevention could be achieved without chemicals, without extra energy input, and with zero moving parts?
That’s exactly what happened when Jingtao Energy deployed its Active Frequency-Conversion Electromagnetic Wax & Viscosity Control System on an offshore platform in the Shengli Oilfield.
Before Installation:
- Daily chemical inhibitor dosage: 5 kg
- Hot wash frequency: Every 15–20 days
- Back pressure: Rising steadily, risking shutdown
- Maintenance cost: ~RMB 95,000 per cleaning cycle (including vessel, labor, and lost production)
After 12+ Months of Operation:
- Zero chemical additives used
- Hot wash interval extended to >120 days
- System operated continuously with zero failures
- Tubing pressure stabilized; back pressure reduced by 0.1–0.3 MPa
- Estimated annual savings: Over RMB 1 million per well
The system leverages pulsed electromagnetic fields (60–80 mT) to alter wax crystal formation at the molecular level—delaying precipitation, reducing viscosity by 30–80%, and increasing dissolved wax capacity by over 5.5×. With an effective range of ≥1,500 meters and magnetic hysteresis lasting >4 hours, it ensures long-lasting protection even after power interruption.
Unlike mechanical or thermal methods, this solution is fully automatic, explosion-proof, and compatible with photovoltaic power systems—making it ideal for remote or offshore environments.
Result? Stable production, lower OPEX, zero pollution, and a future-proof alternative to legacy wax control.
