ABSTRACT:
A pressure packer assembly adapted for positioning in a bore of a gas or oil well, and having a compressible sealing element which when actuated prevents fluid flow from below the compressed sealing element, with the packer assembly including the sealing element, having a lateral opening therethrough so that fracturing fluid passes through such lateral opening in the packer assembly into fracturing contact with the well bore. A notch gun coacting with the packer is also disclosed. A method is also disclosed of fracturing the formation traversed by the well, and comprising positioning the packer assembly in the well at a selected zone and actuating the packer sealing element into pressurized engagement with the interior periphery of the well, and then pumping fracturing liquid via the lateral opening in the packer assembly directly into fracturing engagement with the confronting area of the zone of the formation, to fracture the formation at such zone commencing at the opening and extending outwardly therefrom. The packer assembly can be rotated about its lengthwise axis relative to the fractured portion of the zone, whereby the opening in the packer assembly faces a different section of the periphery of the well to provide for further fracturing of the formation commencing at the opening and extending outwardly therefrom in a direction different from the direction of fracturing of the first fracturing location.
