US Patent 10151164 Single-trip casing cutting and bridge plug setting

A downhole tool may include a bridge plug releasably coupled to a casing cutting tool. The bridge plug may be set within a wellbore and the casing cutting tool may be used in a milling or perforating operation during a single downhole trip of the downhole tool. A method for using a downhole tool may include setting the bridge plug in a wellbore and performing a casing cutting operation during a same downhole trip. The casing cutting tool may be a section mill and a section milling operation may be performed before or after uncoupling the bridge plug from the section mill while downhole. The section milling operation may remove an entire portion of casing within a region of the wellbore for receiving a cement plug. The casing cutting too may be a perforation tool and perforating may be used to remove portions of casing.
