  • Patent number: 10330445
    Abstract: A shaped charge produces an explosive jet utilizing a cylindrical liner surrounded by tracks of explosives. The tracks of explosives are located on the curved surface of the cylindrical liner in a spiral. The tracks of explosives are wrapped around the cylindrical liner in a spiral at an angle to the charge axis. The angle is determined as an angle that assures that the flow speed of the collapsing cylindrical liner is subsonic compared to the sound speed in the material of the collapsing cylindrical liner. The angle also can be selected and varied to directly control the speed of a non-stretching jet, as well as a velocity gradient to produce a stretching jet.

  • 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.

The cavitation pin has a truncated right conical shape with a base diameter to length ratio of 0.7:1 to 1.5:1. The ratio of the open-poled dished liner diameter:cavitation pin fore portion major base diameter is 2:1 to 4:1. Upon detonation, the cavitation pin leads the explosively forged liner in the explosively formed projectile assembly. The leading pin causes cavitation in water resulting in an increase in the velocity of the explosively formed projectile.

    Abstract: In the hemispherical family of axisymmetric circular linear shaped charge liners, this novel swept hemispherical profile shaped explosive device produces a stable jet with the ability to aim the jet by moving the initial explosive impulse ring on the liner surface inward or outward from the pole of the liner profile. The precision of the circular simultaneous initiation of the HE billet is accomplished by the use of a novel Circular Precision Initiation Coupler (CPIC). This CPIC uses a single point initiation to create a simultaneous peripheral detonation of the HE billet that collapses and drives the swept liner into a high speed stretching hollow cylindrical projectile, or more commonly called a jet in the industry.

  • Patent number: 8677902
    Abstract: A precision coaxial water jet disruption explosive device system that holds a blasting cap precisely to the surface of a cylindrically cut positioned plastic explosive that couples a detonation shock wave into water surrounding a hollow forming cavity. A pressure relief vent enables the water filled system to be assembled without deforming the thin walled hollow jet forming cavity, enabling forming repeatable supersonic jets on centerline axis. This system is positioned with two triangular pivot legs and aligned with two fan light beams or a line sight to define a projected jet route to deliver a water jet that can cut through over 1 inch of steel and disrupt target objects more than 9 feet away. This system is used to disable improvised explosive devices, and other dangerous objects, without detonating the targeted explosives and electronic devices such that the contents are destroyed without explosion sequences occurring.

  • Patent number: 8627707
    Abstract: An improved test setup facility, referred to as a “Quick Development Cell” (QDC), which allows for rapid turnaround testing with valuable feedback to a design engineer. Because the QDC allows for quick and efficient testing at a sufficient frequency, QDC tests are compatible with production quality control. In addition to fostering improvement of the API's Section 2 type tests using stressed natural rock for benchmark experiments, the QDC tests allow for progress to be made towards the development of a flow-optimized shape charge and superior well performance.
