SYSTEMS AND METHODS FOR SECONDARY SEALING OF A PERFORATION WITHIN A WELLBORE CASING |
摘要 |
Systems and methods for secondary sealing of a perforation present within a wellbore casing associated with a primary sealing agent. The wellbore casing defines a casing conduit present within a wellbore that extends between a surface region and a subterranean formation. The systems and methods include a sealing apparatus that retains a charge of sealing material with a secondary sealing agent and is conveyed within the casing conduit to within a threshold distance of the perforation. The systems and methods further include selectively releasing the charge of sealing material from the sealing apparatus, such as by a release mechanism, to deliver the charge of sealing material to the perforation, to supplement the primary sealing agent (and/or a seal formed thereby), and/or to decrease a flow rate of a fluid from the casing conduit through the perforation. |
