Patent number: 9016377Abstract: A chopper mechanism for providing a fiber to a fluid at an oilfield. The chopper mechanism may be employed to process the fiber from an uncut form to a cut form in order to provide a mixture of the fluid and the fiber with flowback inhibiting character. Techniques of employing the chopper mechanism may be utilized at the site of an oilfield for applications such as fracturing, cementing, and drilling. Additionally, the chopper mechanism itself may be made available as a large high capacity chopper assembly, or a smaller handheld chopper gun for slower rate fiber supply operations.Type: GrantFiled: December 4, 2012Date of Patent: April 28, 2015Assignee: Schlumberger Technology CorporationInventors: Edward Leugemors, Raafat Abbas, Erik Rhein-Knudsen, William R. Mcintire, Jean-Louis Pessin

Patent number: 7000632Abstract: A valve apparatus that has a longitudinal axis therethrough comprises a valve seat member, a valve closure member, a fluid flow path, and a screening member. The valve seat member comprises a hollow bore and a first frustoconical contact surface. The valve closure member comprises a body and a second frustoconical contact surface that is adapted to seal against the first frustoconical contact surface. The valve closure member is movable along the longitudinal axis of the valve apparatus. The fluid flow path extends through the bore of the valve seat member and between the valve seat member and the valve closure member. This fluid flow path is closed when the second frustoconical contact surface is sealed against the first frustoconical contact surface. The screening member is attached to at least one of the valve closure member or the valve seat member, and screens particles from fluid passing through the fluid flow path when the valve closure member approaches the valve seat member.Type: GrantFiled: January 28, 2004Date of Patent: February 21, 2006Assignee: Schlumberger Technology CorporationInventors: William R. McIntire, Hau N. Pham, Joseph M. Hubenschmidt, Mark E. Upton

Patent number: 5046856Abstract: Plug flow through a series of tanks in fluid communication is effected by the addition of radial flow impeller means to at least one of the tanks. Plug flow through the tanks allows for sufficient residence time in the series of tanks to effect complete hydration of a hydratable gel for using in well treatment operations such as fracturing, acidizing and gravel packing.Type: GrantFiled: September 12, 1989Date of Patent: September 10, 1991Assignee: Dowell Schlumberger IncorporatedInventor: William R.

Patent number: 4808004Abstract: This invention is directed to a mixing apparatus for mixing liquids and particulate solids which comprises an enclosed cylindrical housing with an inlet means and a liquid/solid outlet means coupled to said housing and a slinger disposed within said housing which comprises a flat disc with a plurality of circumferentially spaced vertical vanes and a cylindrical outer wall at the outer periphery of the cylindrical flat disc.Type: GrantFiled: May 5, 1988Date of Patent: February 28, 1989Assignee: Dowell Schlumberger IncorporatedInventors: William R. McIntire, James C. Ritter

Patent number: 4671665Abstract: The machine disclosed herein is useful for blending a particle containing stream, especially a stream of solid particles, with fluids. In a typical operation, sand is mixed with a gel composition to obtain a fluid mixture suitable for stimulation treatments of oil and gas wells. The machine includes a slinger with a topside surface which may be of toroidal concave configuration. The machine also includes an impeller, of a vortex configuration, that is fastened underneath the slinger. In this machine, entrained gas is carried into the fluid phase by the particle containing stream, but the gas is then "exhausted" from the mixture through interior and exterior air exhaust channels and spaces that are built into the machine. A slinger which is particularly adapted for use in such a machine is also disclosed.Type: GrantFiled: May 12, 1986Date of Patent: June 9, 1987Assignee: Dowell Schlumberger IncorporatedInventor: William R. McIntire

Patent number: 4432345Abstract: A secondary concentrator for use in receiver systems for linear focusing primary concentrators is provided with reflector wings at each end. The wings increase the capture of light rays reflected from areas adjacent the rim of a primary concentrator, increasing the apparent aperture size of the absorber as viewed from the rim of the primary concentrator. The length, tilt, and curvature of the wing reflectors can be adjusted to provide an absorber having a desired aperture aspect.Type: GrantFiled: March 13, 1981Date of Patent: February 21, 1984Assignee: The United States of America as represented by the United States Department of EnergyInventor: William R.

Patent number: 4419984Abstract: A cylindrical radiant energy collector is provided which includes a reflector spaced apart from an energy absorber. The reflector is of a particular shape which ideally eliminates gap losses. The reflector includes a plurality of adjacent facets of V shaped segments sloped so as to reflect all energy entering between said absorber and said reflector onto said absorber. The outer arms of each facet are sloped to reflect one type of extremal ray in a line substantially tangent to the lowermost extremity of the energy absorber. The inner arms of the facets are sloped to reflect onto the absorber all rays either falling directly thereon or as a result of reflection from an outer arm.Type: GrantFiled: February 14, 1980Date of Patent: December 13, 1983Assignee: University Patents, Inc.Inventor: William R.
