Abstract: A limited entry perforating phased gun system and method for accurate perforation in a deviated/horizontal wellbore is disclosed. The system/method includes a gun string assembly (GSA) deployed in a wellbore with shaped charge clusters. The charges are spaced and angled such that, when perforated, they intersect at a preferred fracturing plane. Upon fracturing, the fractures initiate at least principal stress location in a preferred fracturing plane perpendicular to the wellbore from an upward and downward location of the wellbore. Thereafter, the fractures connect radially about the wellbore in the preferred fracturing plane. The fracture treatment in the preferred fracturing plane creates minimal tortuosity paths for longer extension of fractures that enables efficient oil and gas flow rates during production.

Abstract: A hydraulic time delay system and method in a wellbore tool is disclosed. The system/method includes an actuation mechanism which allows pressure to act on a functional piston in the wellbore tool. The movement of the piston is restrained by a partially or filled reservoir which is allowed to exhaust through a flow restriction element. The restriction element comprises standard metal tubing with a known inner diameter and is cut to an exact length as predicted by fluid dynamic modeling. A time delay and rate of piston movement desired for the downhole tool, between a trigger event such as pressure and a functional event, can be tuned with parameters that include the length and diameter of the tubing, reservoir fluid viscosity and number of tubes in parallel. In another embodiment, a secondary plugging element added to the reservoir controls the rate of piston movement and time delay.

Abstract: An apparatus and method for providing a time delay in injection of pressured fluid into a geologic formation. In one aspect the invention is a toe valve activated by fluid pressure that opens ports after a predetermined time interval to allow fluid to pass from a well casing to a formation. The controlled time delay enables casing integrity testing before fluid is passed through the ports. This time delay also allows multiple valves to be used in the same well casing and provide a focused jetting action to better penetrate a concrete casing lining.

Abstract: An improved perforating gun with novel endplates is disclosed along with a corresponding method of assembly. The endplate includes a base with a first end separated from a second end separated by a curved sidewall centered around a longitudinal axis and a set of tube tabs flexibly coupled to the base and extending from the second end. Each of the set of tube tabs has a retaining lip and is generally oriented in a direction of the longitudinal axis. The endplate may include an optional carrier tab with an integrated alignment pin. Selected embodiments may also include a zero-tension connector with a sliding contact mounted within a cavity of a housing, a through-wire connected to the sliding contact. The novel endplate reduces the cost and complexity of manufacture and installation.

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 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: An artificial lifting system for bringing a formation fluid from a horizontal well to the surface, the system including an outer production tubing that extends into the well, from a head of the well to a lateral portion of the well; and a hybrid valve attached to a distal end of the outer production tubing. The hybrid valve has two orientations, a first orientation for which the hybrid valve acts as a one-way valve, and a second orientation for which the hybrid valve acts as a conduit.

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 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.
