ABSTRACT:
A method and apparatus for conducting wireline operations in oil and gas wells under blowout conditions is disclosed, wherein a releasable annular wireline blowout preventer is provided, whereby wireline operations may be conducted under normal operating conditions by only using a short riser and a releasable annular wireline blowout preventer. Under blowout conditions, a second riser may be attached to the releasable annular wireline blowout preventer to quickly enable a wireline suspended tool to be safely removed from the well, along with the releasable wireline seal assembly means of the blowout preventer.
