Abstract:
In one system, there is an emergency pipe stroker tool, wherein the emergency pipe stroker tool is configured to act as a first mechanical barrier for a well. Further, there is an emergency quick disconnect tool in communication with the emergency pipe stroker tool, wherein the emergency quick disconnect tool comprises a connector assembly and a fluid conduit in communication with the well, and further wherein the connector assembly is configured to simultaneously detach from the well and to seal the well. Further still, there is a cement retainer in communication with the emergency quick disconnect tool and the emergency pipe stroker tool, wherein the cement retainer is configured to act as a second mechanical barrier for the well, wherein, the emergency pipe stroker tool, the emergency quick disconnect tool, and the cement retainer act in coordination to seal a well while establishing the multiple mechanical barriers.

Claim (Index 18):
A method of sealing a well with multiple mechanical barriers, wherein the method comprises the steps of:\n i) providing a blowout preventer system with an emergency pipe stroker tool for insertion into the well, wherein the emergency pipe stroker tool is configured to act as a first mechanical barrier for well control operations; ii) attaching a perforating gun to a cement retainer comprising at least one flapper valve, at least one check valve, or combinations thereof, and running the cement retainer comprising the at least one flapper valve, the at least one check valve, or combinations thereof and the perforating gun into the well, wherein the cement retainer comprising the at least one flapper valve, the at least one check valve, or combinations thereof, is configured to act as a second mechanical barrier for well control operations; iii) inserting a work string of tubulars with a stinger into the well; iv) forming an opening in the cement retainer comprising the at least one flapper valve, the at least one check valve, or combinations thereof, with the stinger; v) attaching the blowout preventer system within the well; vi) inserting the emergency pipe stroker tool into the opening in the cement retainer comprising the at least one flapper valve, the at least one check valve, or combinations thereof, wherein the emergency pipe stroker tool is in an extended position, and wherein the emergency pipe stroker tool is in mechanical communication with the blowout preventer and the cement retainer at the opening to provide the first mechanical barrier; vii) gripping at least one tubular of the work string of tubulars with a gripping mechanism for holding the work string of tubulars within the well; viii) attaching an emergency quick disconnect tool to the well, wherein the emergency quick disconnect tool is in mechanical communication with the emergency pipe stroker tool; ix) closing at least one blowout preventer of the blowout preventer system and lowering the emergency pipe stroker tool further into the well and within the cement retainer; x) firing the perforating gun to create a plurality of perforations into a surrounding formation proximate to the well; and xi) depositing a material into the plurality of perforations for sealing the well with multiple mechanical barriers.
