Patent number: 10344542Abstract: A centralizer assembly is disclosed that allows for the assembly to be deployed in-situ. The centralizer assembly includes flexible members that can be extended into the well bore in situ by the initiation of a gas generating device. The centralizer assembly can support a large load carrying capability compared to a traditional bow spring with little or no installation drag. Additionally, larger displacements can be produced to centralize an extremely deviated casing.Type: GrantFiled: February 23, 2017Date of Patent: July 9, 2019Assignee: National Technology & Engineering Solutions of Sandia, LLCInventors: Mark C. Grubelich, Jiann-Cherng Su, Steven D. Knudsen

Patent number: 9534879Abstract: A gas powered fluid gun for propelling a stream or slug of a fluid at high velocity toward a target. Recoil mitigation is provided by a cavitating venturi that reduces or eliminates the associated recoil forces, with minimal or no backwash. By launching a quantity of water in the opposite direction, net momentum forces are reduced or eliminated.Type: GrantFiled: January 22, 2016Date of Patent: January 3, 2017Assignee: Sandia CorporationInventors: Mark C. Grubelich, Gerold Yonas

Patent number: 9272296Abstract: A gas powered fluid gun for propelling a stream or slug of a fluid at high velocity toward a target. Recoil mitigation is provided that reduces or eliminates the associated recoil forces, with minimal or no backwash. By launching a quantity of water in the opposite direction, net momentum forces are reduced or eliminated. Examples of recoil mitigation devices include a cone for making a conical fluid sheet, a device forming multiple impinging streams of fluid, a cavitating venturi, one or more spinning vanes, or an annular tangential entry/exit.Type: GrantFiled: October 16, 2013Date of Patent: March 1, 2016Assignee: Sandia CorporationInventors: Mark C.

Patent number: 8176995Abstract: A method and means of minimizing the effect of elastic valve recoil in impact applications, such as percussive drilling, where sliding spool valves used inside the percussive device are subject to poor positioning control due to elastic recoil effects experienced when the valve impacts a stroke limiting surface. The improved valve design reduces the reflected velocity of the valve by using either an energy damping material, or a valve assembly with internal damping built-in, to dissipate the compression stress wave produced during impact.Type: GrantFiled: April 16, 2009Date of Patent: May 15, 2012Assignee: Sandia CorporationInventors: Yarom Polsky, Mark C. Grubelich, Mark R. Vaughn

Patent number: 6253680Abstract: A diversionary device has a housing having at least one opening and containing a non-explosive propellant and a quantity of fine powder packed within the housing, with the powder being located between the propellant and the opening. When the propellant is activated, it has sufficient energy to propel the powder through the opening to produce a cloud of powder outside the housing. An igniter is also provided for igniting the cloud of powder to create a diversionary flash and bang, but at a low enough pressure to avoid injuring nearby people.Type: GrantFiled: February 24, 1999Date of Patent: July 3, 2001Assignee: Sandia CorporationInventor: Mark C.

Patent number: 5861570Abstract: The present invention is a low-energy detonator for high-density secondary-explosive materials initiated by a semiconductor bridge igniter that comprises a pair of electrically conductive lands connected by a semiconductor bridge. The semiconductor bridge is in operational or direct contact with the explosive material, whereby current flowing through the semiconductor bridge causes initiation of the explosive material. Header wires connected to the electrically-conductive lands and electrical feed-throughs of the header posts of explosive devices, are substantially coaxial to the direction of current flow through the SCB, i.e., substantially coaxial to the SCB length.Type: GrantFiled: April 23, 1996Date of Patent: January 19, 1999Assignee: Sandia CorporationInventors: Robert W. Bickes, Jr., Mark C. Grubelich
