Method and System to Protect Legacy Production and to Mitigate the Risk of an Uncontrolled Release from Oil and Gas Wells

摘要

A tool system is provided that can seal perforations or entrance points in a wellbore and reinforce the structure of the wellbore in a single run before a new, nearby wellbore is drilled and stimulated. Embodiments of the present invention comprise a body and bladder combination that is lowered into a wellbore to a predetermined position. In some embodiments, the bladder is positioned around an outer surface of the body and then inflated to seal and reinforce the wellbore. In various embodiments, the bladder is positioned in the body and then flushed to a second predetermined position and filled with a fluid to seal perforations and reinforce the wellbore. A two-reel system can be used to lower the combined body and bladder as well as only the bladder. The bladder-on-body embodiments and the bladder-in-body embodiments can be used in either vertical or horizontal wellbores.
