Downhole Tool Apparatus with Slip Plate and Wedge

A downhole tool for use in a well bore, comprising:

• a center mandrel;
• a slip means configured to grippingly engage the well bore when activated, so as to prevent movement of the downhole tool within the well bore;
• a sealing member configured to sealingly engage the well bore to divide fluid within the well bore into at least two distinct fluid volumes, an upper fluid volume and a lower fluid volume;
• and
• a pressure equalization port configured to automatically equalize pressure between the upper fluid volume and the lower fluid volume during removal of the downhole tool from the well bore.
