Plasma Impulse Technology to Enhance Oil Recovery in HTR Reserves

The equipment was development by AO NPP VNIIGIS in cooperation with AO NPF GITAS

SCOPE OF APPLICATION

  • Treating of oil and gas well perforation intervals in the late stages of development
  • Treatment of filters at gas wells

FEATURES AND ADVANTAGES

A borehole source of directional periodic elastic oscillations with sufficient power (up to 96MPa) to destroy the sealed space, increase the mobility of the borehole fluid, on the other hand, preserving the integrity of the cement ring.  

In producing wells

  • cleaning of perforated intervals from colmated rock particles and drilling mud residues, its filtrate, as well as sediments of salts and asphaltene in the porous medium.
  • opening of natural reservoir fractures and formation of new ones. 
  • slight change in porosity with a significant increase in permeability    

In injection wells

  • injection profile control,
  • for redistribution of injected fluid over interlayers it is not necessary to carry out isolation, drainage measures with the use of various surfactants 

The effect lasts from 6 to 24 months and more, depending on reservoir properties and the stage of field development
