  • Patent number: 10337310
    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.

  • Publication number: 20190195055
    Abstract: A shaped charge comprising 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: 10294752
    Abstract: A catch-and-release tool conveyed with a well casing for use in a wellbore comprising an outer housing having flow ports therethrough, a functioning apparatus disposed within the outer housing comprising a movable member/sleeve and a holding device, and a blocking apparatus comprising a blocking member configured to block the flow ports in a first position. When a ball deployed into the well casing passes through the tool in a downstream direction and moves back in an upstream direction, the restriction element engages onto the holding device and moves the movable member such that a port is exposed to up hold pressure and the blocking member travels to a second position in a reverse direction unblocking flow ports and enabling fluid communication to the wellbore. The ball is thereafter released in an upstream direction.

  • Patent number: 10138725
    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.

  • Publication number: 20180171741
    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 WST is positioned along with the RSM at a desired wellbore location. After the WST sets and seals the RSM, a conforming seating surface (CSS) is formed in the RSM. The CSS is shaped to engage/receive RPE deployed into the wellbore casing. The engaged/seated RPE isolates heel ward and toe ward fluid communication of the RSM to create a fracture zone. The RPE's are removed or left behind prior to initiating well production without the need for a milling procedure. A large ID RSM diminishes flow constriction during oil production.

  • Publication number: 20180106136
    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 includes 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.

  • Publication number: 20170275973
    Abstract: An optimal perforating gun method for accurate perforation in a deviated/horizontal wellbore is disclosed. The method includes a gun string assembly (GSA) deployed in a wellbore with shaped charges arranged in rows in a cluster and a total number of the shaped charges is equal to a total number of the rows. A total number of charges for each cluster in a stage is selected with the best statistical probability for a desired number of perforations in the cluster. The number of charges and the number of rows per each cluster in a stage is optimized such that there is a maximum probability of perforating into a low compression region in an upward and downward direction.

  • Patent number: 9752406
    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.
