  • Publication number: 20170247982
    Abstract: A time delay tool and method in a wellbore casing is disclosed. The tool/method includes a mechanical restraining element, a reservoir for containing a reactive fluid, an actuating device and a wellbore device. When a stored energy is applied on the wellbore device, the actuation device is actuated and enables the reactive fluid in the reservoir to come in contact with the mechanical restraining element. While the mechanical restraining element undergoes a change in shape due to a chemical reaction, a stored energy applied on the wellbore device is delayed by a pre-determined time delay. The amount of the pre-determined time delay is determined by factors that include the reactive fluids, concentration of the reactive fluids, geometry and size of the mechanical restraining element.

  • Publication number: 20170247996
    Abstract: A detonating restriction plug element and method in a wellbore casing. The element includes a hollow passage in the restriction plug element that receives a detonating assembly coupled to a mechanical restraining element, and a space for containing a reactive fluid. The mechanical restraining element undergoes a change in shape for a pre-determined time delay due to a chemical reaction when the reactive fluid in the space such as wellbore fluids comes in contact with the restraining element. A firing pin in the detonating assembly is released when the restraining elements changes shape and releases the restraint on the firing pin. The firing pin contacts a detonator in the detonating assembly and causes a detonating event such that the restriction plug element fragments.

  • Patent number: 9725993
    Abstract: A shaped charge that includes 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.

  • Patent number: 9689232
    Abstract: An actuating apparatus for actuating a downhole tool in a wellbore casing comprising an actuating member and a holding device. The actuating member disposed within an outer housing of the downhole tool and the holding device mechanically coupled to the arming member. When a ball deployed into the wellbore casing passes through the downhole tool in a downhole direction and moves back in an uphole direction due to reverse flow, the ball engages on the holding device and functions the actuating member such that a port in the downhole tool is exposed to uphole pressure and actuates the actuating member to travel in an uphole direction.

  • Patent number: 9650866
    Abstract: An apparatus and method for providing a time delay in injection of pressured fluid into a geologic formation. The apparatus comprises 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.

  • Patent number: 9644460
    Abstract: By removing material of low permeability from within and around a perforation tunnel and creating at least one fracture at the tip of a perforation tunnel, injection parameters and effects such as outflow rate and, in the case of multiple perforation tunnels benefiting from such cleanup, distribution of injected fluids along a wellbore are enhanced. Following detonation of a charge carrier, a second explosive event is triggered within a freshly made tunnel, thereby substantially eliminating a crushed zone and improving the geometry and quality (and length) of the tunnel. In addition, this action creates substantially debris-free tunnels and relieves the residual stress cage, resulting in perforation tunnels that are highly conducive to injection under fracturing conditions for disposal and stimulation purposes, and that promote even coverage of injected fluids across the perforated interval.
