Abstract: A liner for a shaped charge comprising powdered heavy metal tungsten coated with a metal binder coating compressively formed into a liner body. Each of the powdered heavy metal particles are substantially uniformly coated with metal binder coating. The preferred powdered heavy metal particles are comprised of tungsten. Optionally, the liner for a shaped charge includes a lubricant intermixed with the coated heavy metal particles. The metal binder coating is selected from the group consisting of copper, lead, nickel, tantalum, other malleable metals, and alloys thereof, and comprises from 40 percent to 3 percent by weight of the liner. The powdered heavy metal particles comprise from 60 percent to 97 percent by weight of the liner.

Abstract: Disclosed herein is a locator system for a cutting device in combination with a production string. Where the production string has at least one detent along its circumference. The invention also comprises a lock formed to engage the detent, a cutting device, and a body on which the lock is attached. The body is connected to the cutting device such that when the lock is engaged to the detent, the cutting device is operatively connected to the detent and the cutting device is positioned at a location to accurately sever the production string at a desired depth. An alternative embodiment of the detent is a nipple profile and the production string comprises a series of tubing members connected end to end. The tubing members can be a completion tool, tubing, or a combination of both. Also disclosed is a method of using the locator system.

Abstract: A liner for a shaped charge formed from a mixture of powdered heavy metal and a powdered metal binder. The liner is formed by compression of the mixture into a liner body. In one embodiment of the invention, the mixture comprises a range of 50 to 93 percent by weight of tungsten, and 50 to 7 percent by weight of the powdered metal binder. In a specific embodiment of the invention, graphite powder is intermixed with the powdered metal binder to act as a lubricant during formation of the shaped charge liner. The powdered metal binder can be a combination of copper powder, lead, and molybdenum.
