    Abstract: A wellbore perforating system and method with reliable and safer connections in a perforating gun assembly is disclosed. The system/method includes a gun string assembly (GSA) deployed in a wellbore with multiple perforating guns attached to plural switch subs. The perforating guns are pre-wired with a cable having multi conductors; the multi conductors are connected to electrical ring contacts on either end of the perforating guns. The switch subs are configured with electrical contacts that are attached to the electrical contacts of the perforating guns without the need for manual electrical connections and assembly in the field of operations. The system further includes detonating with a detonator that is positioned upstream of the perforating gun. The detonator is wired to a switch that is positioned downstream of the perforating gun.

    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: A loading tube is configured to receive one or more shaped charges to form a perforating gun. The loading tube includes a tubular body extending along a longitudinal axis; a cord passage formed into the tubular body; a retention cutoff formed into the tubular body and configured to receive a detonator cord; and a holding element extending into the retention cutoff and being integrally made with a wall of the tubular body, wherein the holding element is configured to hold the detonator cord into the retention cutoff. The cord passage is configured to receive the detonator cord from a bore of the tubular body and to direct the detonator cord outside the bore of the tubular body.

    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.
