Abstract
A wireline cutter comprises a primary housing with a first axial bore configured to receive a wireline positioned within a well bore, and a first blade mounted within the primary housing and operable to cut the wireline. A method of cutting a wireline in a well bore comprises running a wireline cutter into the well bore, receiving the wireline within the wireline cutter, and cutting the wireline with the wireline cutter. A one-trip cutting system for use in a well bore comprises a wireline cutter, and a coiled tubing cutter. A method for cutting a coiled tubing with a wireline disposed therein comprises running a system comprising a wireline cutter and a coiled tubing cutter into the well bore, cutting the coiled tubing with the coiled tubing cutter, and cutting the wireline with the wireline cutter, wherein both cutting steps are performed in one trip into the well bore.
