Abstract

A- downhole apparatus for engaging a borehole in a subterranean formation includes a tubular body having a longitudinal axis and a first bore, an actuation element having a second bore and is positioned within the first bore of the tubular body, a drilling fluid flow path extending through the first and second bores, and a restriction element trap (200) positioned within the second bore of the actuation element. The actuation element is configured to selectively isolate an operable component of the downhole apparatus from exposure to drilling fluid pressure within the tubular body and the restriction element trap is configured for retentively receiving a restriction element for example a ball (147). A restriction element trap for use with an actuation element for retentively receiving a restriction element and an expandable reamer apparatus for enlarging a borehole in a subterranean formation are also provided. Further provided is a method of activating a downhole apparatus within a borehole of a subterranean formation.

Claims

AMENDED CLAIMS received by the International Bureau on 28 July 2008 (28.07.2008)
1. A restriction element trap for use with a downhole apparatus used for engaging a borehole in a subterranean formation, comprising: a tubular tool body; a tubular body having a longitudinal axis and an inner bore,τthe tubular body sIMablj, positioned within the tool bore of the tubular tool body configured to selectively isolate an operable component of the downhole apparatus from exposure to drilling fluid within the drilling fluid flow path extending through the inner bore of the tubular body and the tool bore of the tubular tool body; a drilling fluid flow path extending through the inner bore of the tubular body; a tubular ball trap sleeve positioned within the inner bore of the tubular body for receiving a restriction element therein; and a tubular plug coaxially aligned and adjacent to the tubular ball trap sleeve, the tubular ball trap sleeve and the tubular plug configured for retentively receiving the .restriction element preventing the restriction element from further movement along the longitudinal axis of the tubular tool body.
2. The restriction element trap of claim 1, further comprising a seal positioned between the inner bore of the tubular body and the tubular plug.
3. The restriction element trap of claim 1, wherein the inner bore of the tubular body comprises an enlarged bore located proximate to portions of the tubular ball trap sleeve and the tubular plug.
4. The restriction element trap of claim 3, wherein a portion of the tubular ball trap sleeve comprises a ductile material for allowing a portion of the tubular ball trap sleeve to yield outwardly into the enlarged bore upon receiving a restriction element therein.
5. The restriction element trap of claim 1, wherein the tubular ball trap sleeve comprises a thin-walled metal conduit and at least a portion of the tubular plug comprises a cylindrical-shaped tetrafiuoroethylene component.
AMENDED SHEET (ARTICLE 19)
23

18. The restriction element trap of claim 15, wherein the ball trap assembly is sized and configured for retentively receiving a restriction element moving in a downhole direction under pressure of drilling fluid within the flow path and for retaining the received restriction element against movement in an uphole direction under substantially the same extent of pressure,
19. A method of activating a downhole apparatus within a borehole of a subterranean formation, comprising: disposing a downhole apparatus within the subterranean formation, the downhole apparatus including a restriction element trap configured for retentively receiving a restriction element and positioned within a bore of an actuation element, positioned for movement within a bore of the downhole apparatus and configured to selectively isolate an operable component from drilling fluid pressure within the downhole apparatus prior to the movement, the restriction element trap including a
AMENDED SHEET (ARTICLE 19)
25 tubular tool body, a tubular body having a longitudinal axis and an inner bore, a tubular ball trap sleeve positioned within the inner bore, and a tubular plug coaxially aligned and adjacent to the tubular ball trap sleeve for retentively receiving a restriction element; flowing drilling fluid through the downhole apparatus via a flow path; disposing theτrestπction ?lem??t into the drilling fluid; receiving the restriction element retentively in the tubular ball trap sleeve of the restriction element trap carried by flowing drilling fluid through the flow path to occlude the flow path; and releasing the actuation element for movement during or after occlusion'of the fluid flow path.
20. Hie method of claim 19, wherein receiving the restriction element retentively in the restriction element trap is effected at a drilling fluid pressure substantially lower than a drilling fluid pressure required for releasing the actuation element.
