Abstract
Wellbore tool assembly to open collapsed tubing includes a chisel head having a first end configured to be positioned within an end of a collapsed tubing portion of a tubular member. The chisel head has a second end opposite the first end. The second end has an outer diameter smaller than an outer diameter of an uncollapsed tubing portion of the tubular member. The chisel head is configured to expand a diameter of the collapsed tubing portion responsive to a movement of the chisel head toward the collapsed tubing portion. The assembly includes a packer attached to the chisel head. The packer is configured to expand responsive to fluidic pressure and to further expand the diameter of the collapsed tubing portion.
