    Abstract: Expandable reamers for enlarging boreholes in subterranean formations include a tubular body 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 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 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.

    Abstract: Ekspanderbare utvidelsesbor omfatter et hus og minst én kniv understøttet av huset. Den minst ene kniven er bevegelig mellom en utstrakt posisjon og en inntrukket posisjon. Den minst ene kniven er i den inntrukkede posisjonen når en glidemuffe er i en første muffeposisjon og en utløsermuffe er i en ublokkert posisjon. Den minst ene kniven er bevegelig til den utstrakte posisjonen når glidemuffen er i en andre muffeposisjon og utløsermuffen er i den ublokkerte posisjonen. Den minst ene kniven er i den inntrukkede posisjonen når glidemuffen er i den andre muffeposisjonen og utløsermuffen er i en blokkert posisjon.

    Abstract: An expandable apparatus may comprise a tubular body, a valve piston and a push sleeve. The tubular body may comprise a fluid passageway extending therethrough, and the valve piston may be disposed within the tubular body, the valve piston configured to move axially within the tubular body responsive to a pressure of drilling fluid passing through the fluid passageway and configured to selectively control a flow of fluid into an annular chamber. The push sleeve may be disposed within the tubular body and coupled to at least one expandable feature, the push sleeve configured to move axially responsive to a flow of fluid into the annular chamber extending the at least one expandable feature.

    Abstract: In one aspect, an apparatus for use downhole is disclosed that in one configuration includes a downhole device configured to be in an active position and an inactive position and an actuation device that includes: a housing including an annular chamber configured to house a first fluid therein, a piston in the annular chamber configured to divide the annular chamber into a first section and a second section, the piston being coupled to a biasing member, a control unit configured to enable movement of the first fluid from the first section to the second section to supply a second fluid under pressure to the tool to move the tool into the active position and from the second section to the first section to stop the supply of the second fluid to the tool to cause the tool to move into the inactive position. In another aspect, the apparatus includes a telemetry unit that sends a first pattern recognition signal to the control unit to move the tool in the active position and a second pattern recognition signal to move the tool in the inactive position.

    Abstract: Expandable reamer tools include an outer body (16), a fluid passageway (17) extending through the outer body, and at least one blade (40) configured to slide relative to the outer body between a retracted position and an expanded position in a direction oriented at an acute angle of less than ninety degrees (90-) to a longitudinal axis of the outer body. In some embodiments, the tools may include a moveable inner sleeve member (30) configured to selectively allow hydraulic fluid pressure within the fluid passageway to act directly on the at least one blade (40). Methods for enlarging a borehole using such expandable reamer tools and methods for removing such expandable reamer tools from a borehole are also disclosed.

    Abstract: 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.
