Abstract: An apparatus for selectively activating a downhole tool by using a Shockwave generated by a detonator assembly may include an outer housing having a bore and an inner housing disposed in the bore of the outer housing. The inner housing may include a chamber having at least one canted surface, an inlet communicating with the chamber and being positioned between the chamber and the detonator assembly, an outlet communicating with the chamber and being positioned between the chamber and the downhole tool, and an energy blocker disposed in the chamber and being freely movable in the chamber as the inner housing changes orientation relative to a vertical datum. The energy blocker axially aligns with the inlet and the outlet when the inner housing is angularly offset less than a specified amount relative to a vertical datum.

Abstract: A downhole tool used in the pressure isolation of adjacent subterranean formations. The downhole tool may comprise flow restriction devices along the outer circumference for impeding flow along the length of the tool. The tool may further comprise a perforating gun and an accumulator. Impeding flow along the length of the tool provides a dynamic flow restriction within the wellbore that precludes fluid flowing from one subterranean zone to an adjacent zone.

Abstract: A method and system for preparing or treating a wellbore in conjunction with a perforating operation. The disclosed perforating gun system includes one or more perforating guns between an uphole flow sub and a downhole flow sub. The uphole flow sub and the downhole flow sub are connected by a fluid bypass that permits fluid to be pumped into the wellbore below the perforating guns. Before perforation, formation-compatible fluid may be pumped through the first and second flow subs via the fluid bypass to displace fluid and debris that may interfere with or cause unwanted damage during perforation. Alternatively, the fluid may be a treating fluid selected to dissolve debris within the wellbore. Following perforation, the fluid may be circulated through the wellbore to remove or dissolve debris created during the perforating process.

Abstract: A buffering device for use in conjunction with a downhole tool string, wherein the tool string includes a ballistics device. The buffering device includes a mandrel attached within a tool string and proximate to the ballistics device. An anchor is disposed on the mandrel and a disk plate is coaxially placed on the mandrel that is slideable thereon. The disk plate is proximate to the ballistic device. A resilient member, such as a spring, is coaxially placed on the mandrel between the disk plate and the anchor. The pressure wave produced by activation of the ballistic device pushes the disk plate toward the anchor and compresses the spring there between. Since the disk plate extends outward into sealing contact with casing lining the wellbore, compression of the spring dissipates energy waves produced by activation of the ballistic device.
