An apparatus for use downhole is disclosed that, in one configuration includes a downhole tool configured to operate in an active position and an inactive position and an actuation device, which may include a control unit. The apparatus includes a telemetry unit that sends a first pattern recognition signal to the control unit to move the tool into the active position and a second pattern recognition signal to move the tool into the inactive position. The apparatus may be used for drilling a subterranean formation and include a tubular body and one or more extendable features, each positionally coupled to a track of the tubular body, and a drilling fluid flow path extending through a bore of the tubular body for conducting drilling fluid therethrough. A push sleeve is disposed within the tubular body and coupled to the one or more features. A valve assembly is disposed within the tubular body and configured to control the flow of the drilling fluid into an annular chamber in communication with the push sleeve; the valve assembly comprising a mechanically operated valve and/or an electronically operated valve. Other embodiments, including methods of operation, are provided.

US Patent:
8047304, Nov 1, 2011
Filed:
Mar 15, 2010
Appl. No.:
12/723999
Inventors:
Steven R. Radford - The Woodlands TX, US
Assignee:
Baker Hughes Incorporated - Houston TX
International Classification:
E21B 10/32
US Classification:
175 57, 175296, 175406
Abstract:
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.

Tools For Use In Drilling Or Enlarging Well Bores Having Expandable Structures And Methods Of Making And Using Such Tools

US Patent:
8459375, Jun 11, 2013
Filed:
Sep 30, 2010
Appl. No.:
12/895166
Inventors:
Steven R. Radford - The Woodlands TX, US
Assignee:
Baker Hughes Incorporated - Houston TX
International Classification:
E21B 7/28, E21B 10/32
US Classification:
175 57, 175268, 175269, 175406
Abstract:
Expandable reamers for enlarging boreholes in subterranean formations include a tubular body and at least one member positioned in openings in the tubular body. The at least one member is configured to move between retracted and extended positions. A push sleeve is disposed at least partially within the tubular body and coupled to the at least one member. The push sleeve moves axially upward to move the at least one member to the extended position in response to a pressure of drilling fluid passing through a drilling fluid flow path in the tubular body. The push sleeve moves axially downward to move the at least one member to the retracted position in response to a pressure of drilling fluid upon a restrictive element disposed within the fluid passageway. The restrictive element disposed within the fluid passageway may be discarded from the fluid passageway by increasing the flow rate through the drilling fluid flow path.

Expandable Reamer Apparatus For Enlarging Boreholes While Drilling

US Patent:
7594552, Sep 29, 2009
Filed:
Oct 16, 2007
Appl. No.:
11/873346
Inventors:
Steven R. Radford - The Woodlands TX, US
Kelly D. Ireland - The Woodlands TX, US
Daryl L. Pritchard - Shenandoah TX, US
Assignee:
Baker Hughes Incorporated - Houston TX
International Classification:
E21B 10/32
US Classification:
175269, 175406
Abstract:
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.

Dorothy P. Enright - Houston TX
Assignee:
Baker Hughes Incorporated - Houston TX
International Classification:
E21B 4900, E21B 4902, E21B 2508
US Classification:
175 58
Abstract:
A method for protecting integrity of a core sample during transport from a subterranean formation to the surface comprising: cutting a core sample from the subterranean formation using a drilling fluid; encapsulating the core sample with an encapsulating material that is separate from the drilling fluid and comprises a property which renders the encapsulating material capable of protecting the chemical integrity of the core sample during transport from the subterranean formation to the surface, wherein the property is other than a property selected from the group consisting of a viscosity which increases in response to a decrease in temperature and an ability to solidify in response to a decrease in temperature; and, transporting the encapsulated core sample from the subterranean formation to the surface.
