ABSTRACT:
The invention describes a system for capping an abandoned well having production casing and surface casing. The system enables the effective sealing of the production casing volume from the surface casing volume such that any gases leaking from either volume can be independently released from independent valves. The system is particularly effective in improving the safety of re-entering an abandoned well.
