Abstract: A technique facilitates perforation and production of desired well fluids from a subterranean reservoir. A well system is deployed in a wellbore and comprises a Y-tool coupled with tubing. The Y-tool has a first branch and a second branch generally opposite the tubing. A bypass tube is coupled with the first branch and a perforating gun assembly extends below the second branch. The perforating gun assembly is disposed adjacent the bypass tube. Additionally, the perforating gun assembly has a plurality of perforating charges, e.g. shaped charges, oriented to create perforations into a surrounding formation without perforating the bypass tube.

Abstract: A technique facilitates perforation, including the perforation of a casing and formation. A shaped charge is formed with a case, a liner, and a high explosive material located between the case and the liner. The liner is formed of a powder material, e.g. a powder metal material. The powder material properties of the liner between an apex of the liner and a skirt of the liner may be selectively varied to provide a desired jet velocity and jet mass of the liner upon detonation of the high explosive material.

Abstract: A perforating gun includes an orienting device retained in a carrier and a charge tube rotatably connected to the orienting device. The orienting device misaligns a center axis of the charge tube with a different second axis such that gravity can cause the charge tube to rotate about the different second axis. The charge tube does not rotate about the center axis of the charge tube while the charge tube rotates about the different second axis.

Abstract: Systems and methods for stimulating a subterranean formation. The methods may include flowing, with a carrier fluid stream (70), an autonomous perforation device (100) within a casing conduit that is defined by a casing string (40) that extends within a subterranean formation (22). The methods further may include retaining the autonomous perforation device within a target region (46) of the casing conduit, flowing a stimulant fluid (80) within the casing conduit and past the autonomous perforation device, and/or stimulating, with the stimulant fluid stream, a portion of the subterranean formation that is downhole from the autonomous perforation device. The systems may include the autonomous perforation device, which may include a perforation assembly (110), a motion-arresting assembly (130), and a fluid flow conduit (150). The systems also may include a hydrocarbon well that includes a wellbore, the casing string, and the autonomous perforation device.

Abstract: A shaped charge for use in perforating a wellbore that includes a shaped charge case, a liner in the case, and explosive between the liner and case. Detonating the explosive inverts the liner to form a metal jet that forms a perforation in a side wall of the wellbore. The outer diameter of the liner open end is set radially inward from the inner diameter of the case opening to define an annular gap. Providing a gap between the liner and case allows more control of distribution of material of the liner into the jet.

Abstract: Methods and apparatus for perforating a formation in a wellbore without perforating a well bore casing. The methods and apparatus include an external casing perforating device configured so as not to perforate the casing. The interior of the perforating device serves as a fluid flow path between the casing and the formation following perforation and a valve in the casing selectively opens and closes the flow path.
