The cap is sized to overlap adjacent portions of the protective shields thereby covering any gaps between the anti-vibration bar and the shields that would expose the boiler tubes to the action of the fluid cleaning medium.Type: GrantFiled: March 17, 2004Date of Patent: October 2, 2007Assignee: The Babcock & Wilcox CompanyInventor: George H.

Patent number: 7275591Abstract: The invention provides a wellhead assembly including a wellhead housing supporting a tubing hanger within its central bore and forming a housing stem port through its outer wall to the central bore. The tubing hanger has a side stem port formed through its body intermediate its upper and lower ends providing access to the central bore of the hanger and being aligned with the housing stem port. The tubing hanger includes a ball valve member having a spherical exterior surface sealed and seated from above and below within the central bore of the hanger. The ball valve member forms a through port extending therethrough aligned with the production bore, and is rotatable in its seated position between open and closed positions with the through port being aligned with the production bore when in the open position. A slot in the exterior surface of the ball valve member if formed proximate the stem port.Type: GrantFiled: September 14, 2005Date of Patent: October 2, 2007Assignee: ERC IndustriesInventors: Gregory Wayne Allen, Men Fung Chin

Patent number: 7275592Abstract: An oil well pumping apparatus for pumping oil from a well to a wellhead provides a tool body that is sized and shaped to be lowered into the production tubing string of the oil well. A working fluid is provided that can be pumped into the production tubing. A prime mover is provided for pumping the working fluid. A flow channel into the well bore enables the working fluid to be circulated from the prime mover via the production tubing to the tool body at a location in the well and then back to the wellhead area. A pumping mechanism is provided on the tool body, the pumping mechanism including first and second gerotors. The first gerotor is driven by the working fluid. The second gerotor is rotated by the first gerotor. The two gerotors are connected with a common shaft. The tool body has flow conveying portions that mix the working fluid and the produced oil as the oil is pumped.Type: GrantFiled: February 21, 2003Date of Patent: October 2, 2007Inventor: Raymond C. Davis

Patent number: 7275593Abstract: A gripper assembly for anchoring a tool within a downhole passage and for possibly assisting movement of the tool within the passage. The gripper assembly includes an elongated mandrel and flexible toes that can be radially displaced to grip onto the surface of the passage. The toes are displaced by the interaction of a driver slidable on the mandrel and a driver interaction element on the toes. In one embodiment, the toes are displaced by the interaction of rollers and ramps that are longitudinally movable with respect to one another. In another embodiment, the toes are displaced by the interaction of toggles that rotate with respect to the toes.Type: GrantFiled: May 3, 2006Date of Patent: October 2, 2007Assignee: Western Well Tool, Inc.Inventors: Duane Bloom, Norman Bruce Moore, Rudolph Ernst Krueger, V

Patent number: 7275594Abstract: A tool string stab guide for axially aligning first tool string components with second tool string components is disclosed. The stab guide has a body with an axial length along a longitudinal axis with a first and a second section. The first section of the body adapted for removable attachment within a diameter of a bore of a tool string component. The second section of the body has a centering element with a flow channel. The ratio of the axial length to the diameter is at least 2:1.Type: GrantFiled: July 29, 2005Date of Patent: October 2, 2007Assignee: IntelliServ, Inc.Inventors: David R. Hall, James McPherson, Patrick Hannigan

Patent number: 7275596Abstract: A method for minimizing the amount of metal crosslinked viscosifier necessary for treating a wellbore with proppant or gravel is given. The method includes using fibers to aid in transporting, suspending and placing proppant or gravel in viscous carrier fluids otherwise having insufficient viscosity to prevent particulate settling. Fibers are given that have properties optimized for proppant transport but degrade after the treatment into degradation products that do not precipitate in the presence of ions in the water such as calcium and magnesium. Crosslinked polymer carrier fluids are identified that are not damaged by contaminants present in the fibers or by degradation products released by premature degradation of the fibers.Type: GrantFiled: June 20, 2005Date of Patent: October 2, 2007Assignee: Schlumberger Technology CorporationInventors: Dean M. Willberg, Christopher N. Fredd, Marina Bulova

Patent number: 7275597Abstract: A method for remotely managing downhole power consumption in a downhole network system is disclosed. The method comprises the steps of monitoring an activation state for each of a plurality of individually activatable electrically-powered modules in a downhole device and determining an optimal activation state for each module according to system demands. The activation state of each module may be selected from the group consisting of activated or deactivated. The method further comprises the step of transmitting a power state switching instruction from a top-hole processing element to a downhole power-consumption state controller over the downhole network. The method also includes the step of switching the selected electrically-powered modules according to the determined optimal activation states.Type: GrantFiled: March 1, 2005Date of Patent: October 2, 2007Assignee: IntelliServ, Inc.Inventors: David R. Hall, David B. Bartholomew, Roger O. Koehler
