Mechanism of U-TEM – Sound-Electric Integrated
In the oil and gas layer, U-TEM technology integrates generators that can stimulate both transient electromagnetic and ultrasonic fields to affect the formation.
The sound-electric integrated actions can destroy the structure of the plug, generate new microfracture flow channels, reduce the interfacial tension of the fluid and the viscosity of the crude oil.
Ultrasonic sound source
After ultrasonic vibration (0-4min), original cracks on the rock sample developed into micro-cracks.
In severe conditions
- Scale creates a significant restriction, or even a plug, in the production tubing.
- Paraffin can also form at the perforations, or inside the formation, reducing oil production.
- Viscosity reducing
Crude oil emulsification
- Interfacial tension lowering
Periodic expansion and construction of pore diameter
Electric field force
After ultrasonic treatment for 30min, the viscosity of crude oil was greatly reduced by 30-50% at all temperatures
After 30 minutes of operation, the oil emulsified and the viscosity decreased.
Why you choose U-TEM
- Green and environment-friendly
U-TEM is a Pure physical method and new-fluid-free operation, it will not introduce any potential pollution and damage to the reservoirs;
- Significant effect for improving productivity
U-TEM is suitable for all types’ plugging removal of reservoir pollution and can overall solve the plugging problem of oilfields;
- Flexible Designed Operation
Pro-job design for each U-TEM operation ensures to meet all specific goals;
- Easy Operation
only need to connect to the wireline and then lower U-TEM to the target layer, which is simple and easy to operate.
