Abstract: A perforating short gun for use in a horizontal well casing. The gun includes a gun carrier and a charge holder to carry shaped charges. The charge holder is inserted into the gun carrier and a selected length of the gun carrier includes internal features created therein to a depth in an inside wall of the gun carrier. The internal features are located and configured to align with a shaped charge, creating a standoff between the shaped charge and the internal feature such that when the charge is detonated it creates an opening through the internal feature.

Abstract: A re-fracturing method using a perforating gun system in a multistring wellbore casing with an inner well casing installed in an outer well casing. The charges in the perforating system includes include a case, a liner positioned within the case, and an explosive filled within the liner. The liner shaped with a subtended angle about an apex of the liner such that a jet formed with the explosive creates an entrance hole in the inner well casing and the outer well casing; the liner having an exterior surface, the exterior surface substantially conical proximate the apex; the subtended angle of the liner ranges from 100° to 120°. The method includes covering the existing openings with the inner casing, perforating with the perforating system and creating constant diameter entrance holes in the outer casing and fracturing through the inner casing and outer casing.

Abstract: A shaped charge comprising a case, a liner positioned within the case, and an explosive filled within the case. The liner is shaped with a subtended angle ranging from 100° to 120° about an apex, a radius, and an aspect ratio such that a jet formed with the explosive creates an entrance hole in a well casing. The jet creates a perforation tunnel in a hydrocarbon formation, wherein a diameter of the jet, a diameter of the entrance hole diameter, and a width and length of the perforation tunnel are substantially constant and unaffected with changes in design and environmental factors such as a thickness and composition of the well casing, position of the charge in the perforating gun, position of the perforating gun in the well casing, a water gap in the wellbore casing, and type of the hydrocarbon formation.

Abstract: A downhole isolation tool (400) for sealing a well, the downhole isolation tool (400) including a sealing element (410) having an internal surface (411) that defines a bore (401) of the downhole isolation tool (400). The sealing element (410) includes a plastically deformable material that irreversibly deforms when swaged.

Abstract: A wellbore plug isolation system and method for positioning plugs to isolate fracture zones in a horizontal, vertical, or deviated wellbore is disclosed. The system/method includes a wellbore casing laterally drilled into a hydrocarbon formation, a wellbore setting tool (WST) that sets a large inner diameter (ID) restriction sleeve member (RSM), and a restriction plug element (RPE). The RPE includes a first composition and a second composition that changes phase or strength under wellbore conditions. After a stage is perforated, RPEs are deployed to isolate toe ward pressure communication. The second composition changes phase to create flow channels in the RPE during production. In an alternate system/method, the second composition changes phase or strength thereby deforming the RPE to reduce size and pass through the RSM' s. The RPEs are removed or left behind prior to initiating well production without the need for a milling procedure.
