A low pressure, high temperature composite bridge plug. The bridge plug comprises a mandrel with a plurality of slips disposed therearound. A wedge is initially attached to said mandrel and in planar contact with the slips for forcing the slips radially outwardly into gripping engagement with a wellbore. An elastomeric sealing element is disposed on the mandrel and compressed between the wedge and a shoulder on the mandrel to expand the packing element radially outward into sealing engagement with the wellbore. A plurality of ratchets retained in a ratchet body grippingly engage the mandrel to prevent the plug from unsetting. The mandrel, slips, wedge and ratchet body are preferably made of non-metallic, composite materials for easy drilling.
