Plasma pulse treatment of the reservoir
Novas Energy Services restores and creates filtration channels in the near-wellbore zone without chemical additives — at any water cut and in reservoirs of any geological complexity.
- 25 000–28 000 °C
- plasma discharge temperature
- 50–53 мкс
- pulse duration
- 1–12 000 Гц
- broadband source range
- > 1500 м
- channel formation radius from the treatment point
How it works
A directional plasma pulse in the perforated interval
A high-voltage current of 3,000–5,000 V is applied to electrodes shorted by a calibrated conductor. Its explosion creates plasma whose instant expansion forms a shock wave with overpressure many times above reservoir pressure.
The generator acts as a broadband non-linear exciter at 1–12,000 Hz: resonant oscillations clean existing filtration channels and create new ones more than 1,500 metres from the treatment point.
Advantages and applications
What the technology delivers in the field
- Environmentally clean: works in natural geological conditions without chemical additives
- Plasma pulse treatment (PPT) is applied at any water cut
- Improves permeability of the near-wellbore zone of producing and injection wells and of the pay zone as a whole
- Significantly increases oil flow rates at fields in a late stage of development
- Multiplies injectivity of injection wells regardless of their previous purpose
- Affects wells adjacent to the treated one, which respond with increased production
- Delivers positive results in reservoirs of any geological complexity
- Safe in operation
- Shortens well commissioning time and time to stable production
Field of application
- 01Inducing inflow during well completion in reservoirs of any geological complexity
- 02Increasing production rates of producing wells at any water cut
- 03Increasing production at fields in a late stage of development
- 04Increasing injectivity of injection wells in reservoirs of any complexity
- 05Levelling the injectivity profile of injection wells
