Patent number: 10815772Abstract: A detection system and method for a well site is provided. The well site has a surface rig and a surface unit. The surface rig is positioned about a formation and a surface unit. The detection system includes a well site component deployable from the surface rig via a conveyance, well site equipment positioned about the well site and having a bore to receive the well site component therethrough; and base units. The base units include scanners positioned radially about the bore of the well site equipment. The scanners detect an outer surface of the well site component and generate combinable images of the well site component whereby the well site equipment is imaged.Type: GrantFiled: February 12, 2016Date of Patent: October 27, 2020Assignee: NATIONAL OILWELL VARCO, L.P.Inventors: Darren Mourre, Russell C.

Patent number: 10787737Abstract: A coating for a diamond table of a cutting element is described. The coating is employed to fill a plurality of voids left by the manufacturing process that compromise the integrity of the cutting element and the associated downhole tooling. The coating may comprise diamond nanoparticles in a metal matrix and may be used with or without a binder layer applied directly to the diamond table, the coating may alternatively be a pure diamond film coating, and may be employed to fill voids left by the manufacturing process.Type: GrantFiled: November 9, 2016Date of Patent: September 29, 2020Assignee: NATIONAL OILWELL DHT, L.P.Inventors: Anil Kumar, Russell C.

Patent number: 7464765Abstract: An improved ram inner seal assembly used in ram-type BOPs is disclosed. The disclosed invention provides an inner guide seal assembly that comprises a specially shaped guide body and a separate sealing element. When the ram-type BOP is closed, two opposing rams move toward one another, and the inner guide seal assembly guides a wireline (or other tubular) toward the center of the vertical bore through the BOP. The inner guide seal assembly's proximity to the ram body's centerline axis helps ensure that a positive seal is formed and that no damage occurs to the device in the central bore of the BOP. The separate, specially-shaped sealing element can be easily inserted into and removed from the guide body of the inner guide seal assembly for easy replacement.Type: GrantFiled: August 24, 2005Date of Patent: December 16, 2008Assignee: National-Oilwell DHT, L.P.Inventors: C.

Patent number: 7243713Abstract: An improved shear/seal ram assembly used in ram-type BOPs is disclosed. The disclosed invention is a unique shear/seal ram assembly in which rail seal actuators attached to or integrally formed in a planar surface of one shear blade mate with and slide within corresponding rail guide grooves formed in a planar surface of a second shear blade. As the shear blades move over each other, the rail seal actuators slide within the rail guide grooves, eventually coming into contact with a seal actuator plate of a unique blade-to-blade seal assembly placed within a shear blade seal groove. Continued movement of the shear blades over each other causes the rail seal actuators to compress, or “energize,” the blade-to-blade seal of the blade-to-blade seal assembly, thereby providing a pressure tight seal between the shear blade assemblies.Type: GrantFiled: November 29, 2004Date of Patent: July 17, 2007Assignee: National-Oilwell DHT, L.P.Inventors: C. Steven Isaacks, Harry P. Hiebeler, Noe Tony Cordova, Jimmy Livingston, Russell C. Gilleylen

Patent number: 5662312Abstract: A pressure containing wireline sheave mechanism having a sheave body defining an opening within which is received a sheave housing which cooperates with the sheave body to define a circular internal sheave chamber which is exposed to operating pressure such as well pressure during well servicing activities. A split sheave having an external wireline groove is located within the internal chamber and is rotatably supported at its inner periphery by bearings. During operation of the wireline sheave mechanism lubricant is supplied to the inner periphery of the internal sheave chamber at a location adjacent the bearing and at a lubricant pressure exceeding well pressure to prevent well pressure induced migration of contaminants from the wireline groove of the sheave to its bearings.Type: GrantFiled: July 22, 1996Date of Patent: September 2, 1997Assignee: Schlumberger Technology CorporationInventors: Henry H. Leggett, Russell C. Gilleylen

Patent number: 5287879Abstract: A single ram wireline BOP mechanism is disclosed which incorporates opposed rams having elastomeric packing capsules and outer elastomeric seals for accomplishing sealing about a wireline extending through the BOP body. The packing capsules cooperate to define a centrally oriented grease chamber into which is injected grease from an externally accessible grease fitting so as to establish grease sealing about the wireline. Grease pressure from the grease chamber is ducted through the BOP rams and into inner cylinders where it acts upon the pressure responsive area of a free piston contained therein. The grease pressure develops a force on the free piston which acts against the ram to enhance the closing force of the ram.Type: GrantFiled: April 13, 1993Date of Patent: February 22, 1994Assignee: Eastern Oil Tools Pte Ltd.Inventors: Henry H. Leggett, Lionel M. Gingras, Russell C. Gilleylen
