Method for fracking wells using a packer to form primary and secondary fracs and seal intervals for hydrualic fracturing

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;
• installing a packer in the perforated liner at a first interval in the formation;
• packer jack fracking the first interval by inflating the packer 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 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 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.

• hydraulically fracturing the first packer fractured formation by injecting a fracking fluid through the packer and the openings in the perforated liner to form a first hydraulically fractured formation;
• deflating and moving the packer to a third interval in the formation;
• packer jack fracking the third interval and sealing the second interval by inflating the packer and deforming the perforated liner into the formation to form a third packer fractured formation;
• and
• hydraulically fracturing the second packer fractured formation by injecting the fracking fluid through the packer and the openings in the perforated liner to form a second hydraulically fractured formation.
