ABSTRACT:
This specification discloses a method of creating a horizontally disposed fracture in a subterranean formation that is penetrated by a wellbore. Two packers are set in the wellbore against the formation to be fractured to define with the wellbore and intermediate the packers a fracture treatment zone. Hydraulic pressure is applied to the fracture treatment zone in an amount slightly less than that required to create a vertical fracture in the formation. Acoustical energy is applied in the fracture treatment zone to form a resonant condition therein and to provide rigid coupling of acoustic stress pulses between the packer and the formation and form a horizontal fracture in the formation. The horizontal fracture is propagated into the formation by the continued application of the hydraulic pressure to the fracture treatment zone.
