Abstract:
The present invention is to a packer plug that can be tripped into a particular location in a well bore and set using slips or expansion rings and packer elements. The plug presents little flow resistance because of its wide inner diameter throat through the mandrel. A ball seat at an upper end allows for the sealing of the interior passage. The ball can be flowed upward or dissolved to remove the seal and allow flow through the plug.

Claim (Index 6):
A method of sealing a well bore comprising:\n providing a bridge plug having a mandrel with a tubular body, collet and a passageway through the tubular body; providing a ball seat at an upper end of the mandrel for receiving a ball to seal flow through the mandrel body; mounting a packer element to the mandrel for selectively sealing flow outside the mandrel body; slidably mounting an upper conical body on the mandrel; slidably mounting a lower conical body on the mandrel; providing at least one friction ring mounted between the upper conical body and lower sub; providing a setting tool for compressing said lower conical body and said upper conical body; setting said bridge plug in place in a casing by compressing the lower sub towards said upper conical body to force said friction ring along a sloped surface of the upper conical body to expand said friction ring into engagement with said casing to lock said bridge plug in place relative to said casing.
