Abstract: A perforating gun (100) having a tubular housing (110), a tubular carrier (120) and a charge carried (130) by the tubular carrier. The tubular carrier comprises an inside diameter, an outside diameter and an opening disposed between the inside diameter and the outside diameter. The charge comprises a forward end positioned in the opening between the inside diameter and the outside diameter. The tubular carrier increases a collapsible-pressure rating for the housing and positions the charge closer to the formation.

Abstract: In servicing a wellbore having casing cemented therein, an assembly deploys on tubing (coiled tubing or jointed pipe) downhole. Fluid is circulated down the tubing to the assembly, and a perforating gun on the assembly passes the circulated fluid through it. A tool downhole on the assembly is then operated with the circulated fluid passed through the perforating gun. For example, the tool can include a fluid-operated motor and milling tool. To allow the fluid to flow through the gun, an outer housing supports the load between the tubing and operable tool and has an inner flow tube disposed therein. Charges for perforating are supported in the space between the housing and flow tube. Once cleanup or other service is done with the tool, a detonation is initiated for the perforating the casing with one or more charges of the perforating gun. The detonation can be initiated by a deployed device or ball shifting a sleeve to drive a pin into a detonator. Detonating cord can connect the detonation to the charges.

Abstract: A method for well completion employs a combined plugging and perforating operation for creating multiple spaced-apart clusters of perforations and optional stimulation treatments in stages. For each stage to be completed, a frac plug, carried, for example, along a wireline bottom hole assembly with perforating guns, is set in the wellbore distal (toward the toe end of the well) of the most proximal perforation cluster of the previous stage, thereby maintaining open hole conditions that provide adequate flow past the most distal perforation clusters in the current stage and minimizing proppant accumulation in the wellbore from stimulation operations. The method further allows subsequent pump down of tools and equipment even with the plug set in the wellbore.

Abstract: A downhole apparatus for use in a tubular include a mandrel, a first slip, a cone, and a seal element. The mandrel, which can be permanent or temporary, has a first end shoulder. The first slip is disposed on the mandrel adjacent the first end shoulder, and the cone is disposed on the mandrel adjacent the first slip. The cone is movable relative to the first end shoulder to engage the first slip toward the tubular. The seal element is disposed on the mandrel adjacent the cone. At least a portion of the seal element is composed of a dissolvable metallic material and is expandable outward from the mandrel. The expanded portion of the seal element forms a metal seal against the tubular and seals off fluid communication in the annular space between the seal element and the tubular.
