Patent number: 7549485Abstract: An expandable reamer apparatus and methods for reaming a borehole are disclosed, including at least one laterally movable blade carried by a tubular body selectively positioned at an inward position and an expanded position. The at least one laterally movable blade, held inwardly by at least one blade-biasing element, may be forced outwardly by drilling fluid selectively allowed to communicate therewith or by at least one intermediate piston element. For example, an actuation sleeve may allow communication of drilling fluid with the at least one laterally movable blade in response to an actuation device being deployed within the drilling fluid. Alternatively, a chamber in communication with an intermediate piston element in structural communication with the at least one laterally movable blade may be pressurized by way of a movable sleeve, a downhole turbine, or a pump.Type: GrantFiled: November 30, 2004Date of Patent: June 23, 2009Assignee: Baker Hughes IncorporatedInventors: Steven R.

Patent number: 7308937Abstract: An expandable reamer apparatus and methods for reaming a borehole, wherein a laterally movable blade carried by a tubular body may be selectively positioned at an inward position and an expanded position. The laterally movable blade, held inwardly by blade-biasing elements, may be forced outwardly by drilling fluid selectively allowed to communicate therewith by way of an actuation sleeve disposed within the tubular body. Alternatively, a separation element may transmit force or pressure from the drilling fluid to the movable blade. Further, a chamber in communication with the movable blade may be pressurized by way of a downhole turbine or pump. A ridged seal wiper, compensator, movable bearing pad, fixed bearing pad preceding the movable blade, or adjustable spacer element to alter expanded blade position may be included within the expandable reamer. In addition, a drilling fluid pressure response indicating an operational characteristic of the expandable reamer may be generated.Type: GrantFiled: April 27, 2006Date of Patent: December 18, 2007Assignee: Baker Hughes IncorporatedInventors: Steven R.

Patent number: 7178609Abstract: A method and apparatus for running a whipstock into a well bore attached to a combination mill and drill bit, releasing the mill/bit from the whipstock, milling a window in the casing, and drilling a lateral well bore, all in one trip. The mill/bit is provided with a primary cutting structure better suited for milling through the casing, and a secondary cutting structure, better suited for drilling through the earth formation. The secondary cutting structure is initially smaller in diameter than the primary cutting structure. The whipstock can be attached to the mill/bit with a shear bolt supported by a boss on the whipstock, with the boss designed to arrest axial motion of the mill/bit after shearing of the bolt.Type: GrantFiled: August 10, 2004Date of Patent: February 20, 2007Assignee: Baker Hughes IncorporatedInventors: Daniel Hart, Calvin Stowe, II, Trung Huynh, Roy E.

Publication number: 20060048486Abstract: A flexible pouch is provided which has panels (3, 5). A transparent strip (13) is provided on one of the panels and a translucent filter (13a) on the other. The panels are heat sealed together to close the pouch and the integrity of the heat seal is determined by shining ultraviolet light through the clear strip and inspecting the translucent filter (13a) so that imperfections in the seal can be identified. Pouches are packaged into containers (25) which include slots (50) and the full containers are stacked for transport through the plant for further processing in a retort, cooler or the like. This enables a large number of pouches to be easily transported through the plant for further processing after they have been filled and heat sealed. The heat sealing line may include a vision system, or the vision system may be a stand-alone item for inspecting the seal to determine the integrity of the seal.Type: ApplicationFiled: June 4, 2003Publication date: March 9, 2006Inventors: Robert Laing, Lloyd Russell

Patent number: 6739416Abstract: Enhanced stabilization is provided for an eccentric reaming tool when a pilot borehole is undersized with respect to a following pilot stabilization pad (PSP). Alternatively, offset of a rotational axis of at least a portion of the assembly including the reaming tool is employed to accomplish stabilization of the reaming tool. In either case, a reamed diameter larger than a physical diameter of the reaming tool may be drilled. More specifically, an enlarged PSP relative to pilot bit diameter or PSP offset or even pilot bit offset is employed in order to engage a PSP with the wall of a pilot borehole of greater diameter than a physical diameter of the pilot bit. The PSP or pilot drill bit, or both, may be laterally offset, angularly offset, or a combination thereof in order to effect substantially continuous PSP contact with the pilot borehole wall.Type: GrantFiled: March 13, 2002Date of Patent: May 25, 2004Assignee: Baker Hughes IncorporatedInventors: W.
