Fremgangsmåte for å bedre en jordformasjons permeabilitet

摘要

A method for improving the permeability of an earth formation zone surrounding a wellbore formed in the earth formation utilizing hydraulic shockwaves. The selected zone is isolated and fluid is pumped downhole to fracture the earth formation, the fluid extending into the fractures. A shock wave is then created in the fracturing fluid to reduce the presence of illite clays in the formation interstices.
