ABSTRACT:
A gas well cap seal assembly adapted to seal the casing bowl of a gas well and to pressurize the annulus region between the inner surface of the well bore and the outer surface of the well casing which is filled with wet cement. The pressurized annulus aids in the prevention of forming gas bubbles and gas leakage paths in the annulus region.
