Patent number: 11993984Abstract: A downhole coupling mechanism for use in downhole tools that find application in wells exploited by a hydraulic refracturing process. The downhole coupling mechanism connects first and second tubular sections via a tensile load arrangement of wires located in complimentary grooves, a torque arrangement of interlocking lugs and notches on opposite ends, and a seal arrangement. The downhole coupling mechanism provides a thin walled coupling where a screw-threaded connection could not achieve the required tensile load, torque and sealing properties needed. Embodiments of a thin walled anchor and packer including the downhole coupling mechanism are described.Type: GrantFiled: March 30, 2023Date of Patent: May 28, 2024Assignee: Vertice Oll Tools, Inc.Inventors: Christopher Cockrill, Philip Turrell, Cameron Radtke

Patent number: 9347298Abstract: A tie back assembly and method of use is presented. In one method, a tie back seal mandrel is inserted into a tie back receptacle. Both the inner surface of the tie back receptacle and the outer surface of the seal mandrel are tapered to cooperate when mated. A seal assembly forms an annular seal between the tapered surfaces when the mandrel is inserted into the receptacle. Preferably the seal assembly has a burst seal and a collapse seal carried on one of the tapered surfaces, where the seals are spaced apart longitudinally. The seals are positioned at locations along the tapered surfaces to provide adequate wall thickness for support at pressure. Hydrostatic fluid in the wellbore increases the force necessary to withdraw the seal mandrel dues to creation of a lower pressure zone between the spaced apart seals.Type: GrantFiled: February 25, 2013Date of Patent: May 24, 2016Assignee: Halliburton Energy Services, Inc.Inventor: Brock Watson

Publication number: 20030094812Abstract: A connector includes a housing having a bore with a housing groove disposed on an inside surface of the bore with a groove establishing a release angle between a housing groove bottom and a bore inside surface. A retainer defines a spring cavity between a retainer and the release angle and a circular radial canted coil spring is disposed in the spring cavity. A pin having a tapered end and a body diameter sized for sliding engagement with the bore is provided which includes a circumferential groove in the pin body for receiving the coil spring upon insertion of the pin into the bore. A circumferential groove includes a load angle for rotating the coil spring in an orientation in which the major spring axis is parallel to the release angle upon initial withdrawal of the pin from the bore. The coil is further compressed along the spring minor axis and expands radially upon continued withdrawal of the pin from the bore.Type: ApplicationFiled: November 19, 2002Publication date: May 22, 2003Inventor: Peter J.

Patent number: 6565128Abstract: A device and a method for coupling a fluid rail to injectors by a connector, the connector having telescopic tube members extending between a first end and a second end, a sealing member disposed between a first tubular member and the fluid rail, a sealing member disposed between a second tubular member and the injector. The tubes are urged apart by either hydraulic pressure or by a resilient member to form a tight seal between the hemispherical distal ends of the connector to the respective fluid rail outlet and injector inlet. This invention also permits the coupling of a fluid rail to at least one fuel injector by providing a fluid rail, a flexible coupler on the injector inlet, mounting the nested or telescopic connector into both the flexible coupler and the injector inlet, inserting the fluid rail onto the connector and then urging the telescopic connector apart to form a tight seal against the inlet and the outlet.Type: GrantFiled: July 13, 2001Date of Patent: May 20, 2003Assignee: Siemens Diesel Systems TechnologyInventor: Ulrich Augustin

Patent number: 6363581Abstract: A hose clamp is provided for establishing a reliable, fluid-tight, seal between a hose and a receptacle therefore or to another length of hose. The clamp includes a plurality of clamp segments and a span ring, e.g., a spiral wound ring. Each clamp segment includes an arcuate interior surface having a span ring slot therein which is positioned to align with a corresponding span ring slot in an adjacent clamp segment. The span ring has a portion disposed in each span ring slot with the interior surface the span ring approximately flush with the interior surfaces of the segments. Each clamp segment further includes a bore on a first end thereof which is adapted to align with a corresponding bore on an end of an adjacent segment. A fastener, e.g., a screw, may be inserted into the bores to draw the ends of the clamp segments toward each other, thereby tightening the segments of the clamp around the hose and receptacle.Type: GrantFiled: April 10, 2000Date of Patent: April 2, 2002Assignee: JGB Enterprises, Inc.Inventor: Guy Anthony Zipp
