Abstract
An apparatus for abrasive jet cutting comprises an abrasive jet perforating tool coupled rotatably to a tubing string and a horizontal indexing tool coupled connectably to the perforating tool. A tubing swivel, an extension tool with protective sleeve, and an anchor may also be used. A method for abrasive jet cutting comprises determining well parameters for a well; assembling, according to the well parameters, the apparatus for abrasive jet perforating; and using the perforating tool to perforate tubular members in the well. A horizontal indexing tool is used to rotate the perforating tool and the perforating tool is used to cut tubular members in the well. An extension tool with a protective sleeve is used to protect the apparatus. A tubing swivel may be used to allow the perforating tool to rotate freely and an anchor may be used to prevent the perforating tool from moving vertically.
