Title (EN) THE METHOD OF IMPLEMENTATION OF VERSA FRACKING OF OIL AND GAS WELLS
(FR) PROCÉDÉ DE MISE EN ŒUVRE DE FRACTURATION INVERSE DE PUITS DE PÉTROLE ET DE GAZ
Abstract:
(EN) The disclosure in various embodiments is related to a method of versa fracking for increasing oil and gas production rate in well completion stage and obtaining total recovery of oil and gas in later stages of production. The method exposes existing cracks in addition to forming new cracks in the reservoir through a sharp hydrodynamic link in the bottom hole and tubing space filled with air under atmospheric pressure or connected to atmosphere. The method involves running tubing filled with air under atmospheric pressure or connected to the atmosphere into the bottom hole of the well using cable, closing the lower end of the tubing and impacting versa fracking in the reservoir.
(FR) L'invention concerne, dans divers modes de réalisation, un procédé de fracturation inverse destiné à augmenter le taux de production de pétrole et de gaz dans la phase d'achèvement de puits et à obtenir une récupération totale de pétrole et de gaz dans les phases ultérieures de production. Le procédé selon l'invention expose des craquelures existantes en plus de former de nouvelles craquelures dans le réservoir par le biais d'une liaison hydrodynamique nette dans le trou de fond et l'espace de tubage rempli d'air sous pression atmosphérique ou relié à l'atmosphère. Le procédé implique l'étendue du tubage rempli d'air sous pression atmosphérique ou relié à l'atmosphère dans le trou de fond du puits à l'aide de câble, la fermeture de l'extrémité inférieure du tubage et la création d'un impact de fracturation inverse dans le réservoir.
