Claim:
1. A method for fracking a well having a well bore through a formation comprising: installing a perforated liner in the well bore having a plurality of pre-formed openings therethrough; providing a packer having an inflatable element configured for inflation with a pressure sufficient to exert a mechanical force on the formation; installing the packer in the perforated liner at a first interval in the formation; packer jack fracking the first interval by inflating the packer with the pressure between 10,000 psia to 30,000 psia and deforming the perforated liner into the formation to form a first packer fractured formation having a plurality of primary packer jack fracs extending from the well bore and a plurality of secondary packer jack fracs; deflating and moving the packer to a second interval in the formation; inflating the packer to seal an up hole end of the first packer fractured formation; hydraulically fracturing the first packer fractured formation by injecting a fracking fluid through the packer and the openings in the perforated liner into the primary packer jack fracs and the secondary packer jack fracs to form a first hydraulically fractured formation; and packer jack fracking the second interval by inflating the packer and deforming the perforated liner into the formation to define a second packer fractured formation.
