TekMark’s new perforator punches four 5⁄8-inch holes at equal distance around the casing with each stroke. It can be operated from a cable, drop pipe or drill string, and it can be converted for casing sizes from 65⁄8 inches to 24 inches, with wall thicknesses up to 0.375 inches. Punching points are guaranteed for 1 year. The perforator operates off a 12 Vdc 3,500-psi hydraulic pump. The perforator is designed to provide greater flexibility by allowing well development and decommissioning independent from the drill rig.
