Abstract: The invention relates to a system and method for well abandonment, comprising installing a first steel plate comprising a hole having a pipe section attached above the hole, wherein a coupler may be installed to house a stopper which is then positioned below the surface casing having a second steel plate, the capping plate, affixed to the top of the surface casing. The stopper system then acts to prevent the exchange of wellbore fluid into the environment while allowing for proper venting of casing strings by pressure actuating the stopper system against the cap. The coupler further provides for attachment of various gas sampling or other monitoring equipment in for purposes of detection of leaks or other analytical objectives.
