发明名称 One-trip cut-to-release apparatus and method
摘要 Apparatuses and methods allow a downhole anchor device to be cut, released, and retrieved using a single one-trip cutter and removal assembly. The assembly preferably includes a cutter head recessed behind an anchor latch. The latch is landed to the anchor device to be removed and the cutter head is extended therefrom and activated. Once cut by the cutter head, the anchor device is retrieved upon a distal end of the assembly.
