Abstract: A drilling assembly for drilling a subterranean wellbore includes an expandable reamer and an expandable stabilizer. The expandable reamer and the expandable stabilizer each have a tubular body with a longitudinal axis and a drilling fluid flow path extending therethrough. A plurality of blades is carried by the reamer and a plurality of bearing pads is carried by the stabilizer. The blades and bearing pads are outwardly movable from a retracted position to an extended position with respect to the longitudinal axes of the reamer and stabilizer, respectively. The reamer and stabilizer each include an actuation device for moving the blades and bearing pads, respectively, from the retracted position to the extended position.

Abstract: En boresammenstilling for boring av en underjordisk brønnboring innbefatter en ekspanderbar utvider og et ekspanderbart stabiliseringsrør. Den ekspanderbare utvider og det ekspanderbare stabiliseringsrør har hver et rørlegeme med en langsgående akse og borefluid- strømningsbane som forløper derigjennom. Et flertall av blader er båret av utvideren og et flertall av lagerputer er båret av stabiliseringsrøret. Bladene og lagerputene er utover bevegbare fra en tilbaketrukket posisjon til en forlenget posisjon med hensyn til en langsgående akse av henholdsvis utvideren og stabiliseringsrøret. Utvideren og stabiliseringsrøret innbefatter hver en aktueringsanordning for å flytte henholdsvis bladene og lagerputene fra den tilbaketrukne posisjon til den forlengede posisjon.

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.

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: Dispositif d'élargissement pour forer et accroître jusqu'à un diamètre plus grand un trou de sonde dans une formation souterraine, comprenant un corps qui s'étend longitudinalement et qui présente au moins une lame s'en étendant radialement vers l'extérieur, ladite lame comprenant sur elle au moins un couteau, le corps qui s'étend logitudinalement pouvant tourner autour d'un axe d'élargissement pour couper un diamètre d'élargissement, et un ensemble pilote comprenant un trépan de forage pilote, pour forer un trou de sonde pilote d'un diamètre plus petit que le diamètre d'élargissement, et au moins un patin de stabilisation pilote déterminant un diamètre de rotation, dans lequel le trépan de forage et ledit patin de stabilisation pilote sont positionnés et configurés de façon à ce qu'un diamètre de rotation du trépan de forage pilote et le diamètre de rotation dudit patin de stabilisation pilote soient sensiblement le même pendant l'opération, et dans lequel le trépan de forage pilote détermine pendant l'oprération un diamètre de rotation plus grand que le diamètre physique du trépan de forage pilote, et procédé d'utilisation de ce dispositif.

Abstract: The present invention provides a method for maintaining the mechanical integrity and for maximizing the chemical integrity of a core sample during transport from a subterranean formation to the surface, the method involves cutting and encapsulating a core sample with an encapsulating material that increases in viscosity or even solidifies, at temperatures slightly lower than those expected downhole, or relatively early in the transport process. A preferred encapsulating material contains at least one polyglycol or chemically modified polyglycol from the oxyalkylene polymer family. The specific formulation of the encapsulating material differs depending upon the expected downhole conditions. For example, the encapsulating material can include a thickener, a nucleating agent, and a water swellable material or another inert material that is capable of sealing the core sample against water. A preferred nucleating agent would serve both as a heat transfer agent and a crystallization trigger, and therefore would speed up the rate at which the encapsulating material would solidify or increase in viscosity, particularly downhole. The encapsulating material should either solidify or increase in viscosity enough to protect the mechanical integrity and maximize the chemical integrity of the core sample for analysis at the surface. The chemical integrity of the core sample can be further maximized by using the present invention in conjunction with a pressure core barrel.

Abstract: Enhanced stability in a borehole reaming assembly where a pilot drill bit 250 defines a rotational diameter during drilling larger than the pilot drill bit physical diameter is provided by configuring the pilot drill bit 250 and a pilot stabilization pad 218 so that the rotational diameter of the pilot drill bit and a rotational diameter of the pilot stabilization pad are substantially the same during operation. The equalizing of the rotational diameters may be effected either by making the physical diameter of the pilot stabilization pad larger than that of the pilot drill bit, by offsetting the pilot drill bit centroidal rotational axis with respect to the reaming axis, or by offsetting the pilot stabilization pad centroidal rotational axis with respect to the reaming axis.
