The application of plasma pulsing has a two fold effect. In the near wellbore region, it cleans the completed interval of mechanical and chemical damage caused during construction, completion and production operations. In the far field region, the effect of a plasma-pulse in producing strata lies in the initiation of resonance oscillation, which will in turn enhance oil migration to well systems.

Novas Energy’s plasma pulse streamer tool repeatedly releases pulses of stored energy which translate into resonance oscillations in the reservoir. At the nearly instantaneous discharge, a sudden release of energy generates a phase change in the surrounding fluids and results in the release of a “shock wave” with an initial pressure that exceeds the stratum strength by many times but not high enough to damage wellbore tubulars.

The tool operates to create forced periodic fluctuations of considerable amplitude in the strata that is being treated. The Plasma Pulse streamer tool allows for the “shock wave” to propagate controllably through the completed interval and then radiates outward in the producing strata. The plasma-pulse action creates parametric resonance throughout the well system.

The Plasma Pulse Streamer is an ideal broadband, non-linear exciter. The resonance vibrations created in the productive stratum make it possible to clean existing filtration channels and to create new ones at a distance over 1500 meters from the point of initiation of the plasma pulse action.

In addition to the large-scale action as discussed above, this creation of plasma also allows local problems such as poor well drainage to be resolved as paraffin , asphaltenes, scales and other materials are cleaned away.

This plasma-pulse technology can be applied in vertical, deviated and horizontal wells, with the proper conveyance techniques.
