Abstract: A method for controlling a target switch assembly in a chain of switch assemblies includes distributing the chain of switch assemblies in a wellbore; placing a controller at a head of the wellbore; making a first decision, at the controller, to actuate a corresponding detonator of the target switch assembly; transmitting, from the controller to the target switch assembly, a fire command to activate the corresponding detonator; and making a second decision, locally, at the target switch assembly, to activate the detonator, after the fire command from the controller is received.

Abstract: There is a shaped charge for making an asymmetrical perforation into a casing. The shaped charge includes a case extending along a symmetry axis X and having a back wall and an open end; an explosive material located within the case; a liner located within the case, over the explosive material; a booster material; and an asymmetrical feature. The asymmetrical feature is selected to generate an asymmetrical perforation into the casing.

Abstract: A downhole isolation tool for sealing a casing in a well, the downhole isolation including plural parts made of a composite material, each part having a preset functionality with regard to sealing the casing; and a sealing element configured to seal the casing. At least two parts of the plural parts have a single, combined 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: A downhole tool for time delaying a downhole activity. The downhole tool includes a housing having a bore; a moving sleeve configured to move relative to the housing; an electronic valve configured to open and close when receiving an electrical signal; and a switch that is responsive to a fluid pressure inside the bore. The downhole tool electronically counts down a set time.

Abstract: A setting tool for setting an auxiliary tool in a well, the setting tool including a housing having a floating piston, the floating piston separating the housing into a pressure chamber, located upstream the floating piston, and a hydraulic chamber located downstream the floating piston; an internal plug having an upstream end attached to the floating piston and having a downstream end extending into the hydraulic chamber; and a cover-insert member covering the downstream end of the internal plug. The internal plug has an internal passage that fluidly communicates (1) with an internal passage through the floating piston, at one end, and (2) with a port at the other end, and the port is covered by the cover-insert member.

Abstract: An artificial lifting system for bringing a formation fluid from a horizontal well to the surface. The system includes an outer production tubing that extends into the well, from a head of the well to a toe of a lateral portion of the well; and an extraction support mechanism extending in a bore of the outer production tubing.

Abstract: A fluid control system includes a fluid control device configured to be connected to at least one of two casing elements in a well, for controlling a fluid flow between a bore of the fluid control device and a zone located outside the casing elements; and a tracer material located within an inner chamber of a body of the fluid control device, the tracer material being uniquely associated with the fluid control device. The fluid control device is configured to release, when activated, the tracer material out of the inner chamber.
