Abstract:
A method and apparatus of plugging and abandoning a well includes using a plug apparatus and installing bentonite elements in an oil well production casing having a bore. The plug apparatus is lowered into the production casing bore to a selected elevation using a slick line or the like. The apparatus has a tool body and slip dies that are movably mounted upon the tool body to move between extended and retracted positions. Afer the tool body is positioned at a selected location within the casing bore, tension is applied to the slick line to move the slip dies to an extended position wherein the slip dies engage the casing and secure the tool body in a desired location. The casing bore is then displaced with water above the tool body. Bentonite elements are then dumped into the water filled wellbore. The bentonite elements are allowed to swell to form a plug.
