Carlos Jose TASSAROLI has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 9441465
    Abstract: Mechanical connector for the connection and assembly of guns used in the perforation of petroleum producing wells. Each gun has a hollow cylindrically shaped housing whose ends have threaded joints. Explosive shipped-charges are radially set in respective peripheral slots of the gun. Guns are coaxially joined in vertical position within the casing of the well, forming an assembly that includes the firing head and a bottom sub. The joints between consecutive guns and between the bottom sub and the lowermost gun, include tubular adaptor pieces and intermediaries that have respectively a threaded joint end and an opposing end constituted by a bayonet-type locking joint formed by a single reinforced latching bayonet locking tab.

  • Patent number: 8943943
    Abstract: Explosive carrier end plates for charge-carriers utilized in guns for the perforation of petroleum producing wells. Each gun is mounted coupled vertically with similar guns inside the casing of the well, and each gun is a hollow cylinder in the interior of which there is a corresponding tubular carrier that has multiple peripheral mountings for a radial placement of the shaped-charges. The carrier is mounted in the gun by means of a top insulating end plate that has a retractable electrical spring contact capable of pushing upwards, and a bottom insulating end plate. The end plates have a centering clip for anchoring in a respective window of the cylindrical wall of the carrier. Both end plates have a single removable insert axially fitted between two tubular inserts, which present reciprocal guiding and positioning means for a pin-keyway slot to enable mounting with the end plate.

  • Patent number: 8875787
    Abstract: An electromechanical assembly for a series of guns used in the perforation of petroleum producing wells. Each gun is a cylindrical housing having a charge-carrier loaded with explosive charges in contact with a detonating cord which contacts an electronically activated detonator. The guns are joined by intermediary joints and terminate in a bottom sub on its lower end and a firing head at its upper end. The charge-carrier of each gun is detonated, beginning with the bottommost gun. Insulating end plates are on the lower and upper ends of the carrier for centering and anchoring the charge-carriers. An electrical wire runs from a retractable contact pin in each carrier, through the intermediary joint which has a changeover switch sensitive to the high pressures produced by the explosion in the carrier located in the gun immediately beneath it, rupturing a mechanical fuse and allowing the switch to close.

  • Publication number: 20130043074
    Abstract: Electromechanical assembly for connecting a series of guns used in the perforation of petroleum producing wells. Each gun has a cylindrical housing for a charge-carrier loaded with explosive shaped-charges set in radial fashion. The charges are in contact with a detonating cord that is in contact with an electronically activated detonator. The series of guns are joined firmly by intermediary joints and terminate in a bottom sub on its lower extreme, where the series is initiated by a firing head which is connected to the surface with an electrical connection. It is possible to detonate the charge-carrier of each gun, beginning with the bottommost gun that remains active.
