    Abstract: A wellbore select fire switch retaining member system and method with an integrated through wire and ground wire in a switch sub. The system/method includes a retaining member that has a form factor acceptable by a conventional switch sub. The retaining member incorporates an electrical connection to the center pin of a pressure switch. The system further includes a secondary piston aligned with a piston in the switch (switch piston) so that external pressure is fully acted upon the entire switch piston creating a reliable switch connection. Another system includes an integrated retaining member and switch module having a form factor compatible with existing switch subs. The integrated module inputs include a ground wire and a through wire and the outputs include a ground wire, through wire and an arming wire.

    Abstract: A method for fracturing a well casing includes forming plural perforation clusters into a stage N associated with the well casing; fracturing the plural perforation clusters; forming a current stage N+1 by placing a plug within the stage N, to isolate a first subset of the plural perforation clusters from a second subset of the plural perforation clusters; and fracturing a second time the second subset, but not the first subset.

    Abstract: A detonator block for housing a detonator has a body configured to host the detonator; the body having a first end that is configured to be attached to a sub; the body having a second end, opposite to the first end, and configured to connect to a gun; and a printed circuit board located inside the body, the printed circuit board being electrically connected to the detonator. The body has a holder that is configured to hold the detonator inside the body.

    Abstract: A perforating gun system with at least one gun. Each of the perforating guns have charges disposed in a gun carrier that are angled to the longitudinal axis of the gun to achieve a predetermined proppant transport profile into clusters within a stage in a well casing. The perforation tunnels may also have burrs on each side of the casing and acts in initially aiding proppant transport during fracture treatment. A method of tuning a cluster to achieve a desired fracturing treatment based on a feedback from another cluster includes selecting a hole diameter, a hole angle for creating an angled opening, a discharge coefficient, and a proppant efficiency. Moreover, a method of improving perforation charge efficiency.

    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 composite plug for sealing a well includes a mandrel having an internal bore, the mandrel having a first end and a second end, opposite to the first end, and the bore extending from the first end to the second end; plural elements distributed along the mandrel in a given order and configured to seal the well; and a bypass mechanism, different from the bore, built into the composite plug and configured to allow a controlled leak of a fluid from the well, past the composite plug.
