ABSTRACT:
A full bore fracture treating assembly is provided for use on oil and gas wells during a fracture treatment down casing to provide a full bore capability for running a casing packer or perforating gun with wellhead pressure remaining at the surface. The assembly includes a modified tubing hanger which isolates blowout preventors on the well from pressure during the treatment, a section of casing to extend through the blowout preventor stack, and a side outlet spool which enables the pumping of fracturing fluids into the well. In addition, a set of blind ram blowout preventors and a full bore lubricator or a valve can be placed on top of the spool as desired to contain pressure and provide full bore access into the well.
