Abstract: A device and method for selectively closing and opening a flow path through a sealing element. The device includes second and third tubulars positioned within a bore of a first tubular. A sealing element having a bore is positioned between the second and third tubulars within the bore of the first tubular. The sealing element may be connected to one or both of the tubulars. Bores of the second and third tubulars communicate with the bore of the sealing element to provide a flow path. Movement of the third tubular with respect to the second tubular buckles the sealing element inward to selectively close a portion of the flow path. The third tubular may be moved away from the second tubular to reopen the flow path. The sealing element may engage a structure within the bore of the sealing element to selectively close the flow path through the sealing element.

Abstract: A process for hardening tubulars and increasing their surface area for heat transfer can be performed in place in a borehole or on the surface. A pattern is applied to an interior wall with at laser, electron beam or radiation source that is remotely controlled to apply the hardening pattern to the inside or outside wall as inert gas or clean fluid is applied. Pressure differential is applied to the wall so that the non-hardened portions or the negative of the hardened pattern plastically or elastically deform to increase surface area and enhance load resistance of tubular or sheets. Alternatively, wall differential pressure is applied with an insert having a raised pattern on its exterior surface causing the spaces where the pattern is absent to plastically deform to enhance surface area. When done in a borehole annulus pressure or stand pipe pressure is applied or a vacuum is pulled inside the tubular to generate differential pressure for hydro-forming or switching dents in an opposite stable condition. The insert can be removed mechanically, or by dissolving or disintegration. Geothermal and SAGD applications are envisioned.

Abstract: An electric submersible pump (ESP) is coupled with a spaced apart debris removal assembly that is independently supported from a retrievable packer. The debris removal assembly is modular and retains the captured debris for subsequent removal from the well with the retrievable packer. The ESP suction draws in well fluids through the debris retention device. The ESP can be pulled to allow removal of the retrievable packer with the debris removal assembly.

Abstract: Sensor-enabled cutting elements for an earth-boring drilling tool may comprise a substrate base, and a cutting tip at an end of the substrate base. The cutting tip may comprise a tapered surface extending from the substrate base and tapering to an apex of the cutting tip, and a sensor coupled with the cutting tip. The sensor may be configured to obtain data relating to at least one parameter related to at least one of a drilling condition, a wellbore condition, a formation condition, and a condition of the earth-boring drilling tool. The sensor-enabled cutting elements may be included on at least one of an earth-boring drill bit, a drilling tool, a bottom-hole assembly, and a drill string.

Abstract: An earth-boring tool includes a body comprising a pocket in a leading end thereof for accepting at least a portion of a bearing element assembly. A bearing element assembly may be disposed within the pocket, and the bearing element assembly may include a retaining element at least partially disposed in a groove in a sidewall of the pocket and a bearing element. The bearing element may include a distal end having a bearing surface, a proximal end, and a side surface between the distal end and the proximal end, the side surface comprising a feature configured to abut the retaining element, wherein mechanical interference between the feature and the retaining element axially retains the bearing element within the pocket. Methods include disengaging a mechanical retention device retaining a bearing element within a pocket in a body of the earth-boring tool, and removing the bearing element from the pocket.

Abstract: Systems, methods, and devices for evaluation of an earth formation intersected by a borehole using a logging tool. Methods include exciting an upper and lower transmitter; receiving signals at a plurality of receivers between the upper and lower transmitter; estimating a phase shift attributable to a volume of interest of the formation adjacent to a section of the carrier corresponding to the plurality of receivers by estimating phase shifts attributable only to portions of the volume of interest adjacent to corresponding portions of the section between each adjacent pair of receivers of the plurality of receivers; wherein each adjacent pair is positioned at a corresponding distance that is no more than half of the shortest wavelength of those wavelengths associated with the received signals. Estimating a phase shift between an adjacent pair of receivers may be carried out using a first relative phase value; and a second relative phase value.

Abstract: An apparatus for use in a borehole may include a rotor having at least one set of magnetic elements and a cylindrical stator having a winding flowing current in a direction transverse to a long axis of the stator. The polarity of each magnetic element of the rotor may be arranged to alternate along a long axis of the rotor. The stator may be in sliding engagement with the rotor and have a core formed at least partially of laminations aligned along a plane co-planar with the long axis of the stator. Energizing the winding principally causes relative sliding between the rotor and the stator. A method for performing an operation in a borehole includes forming a well tool having at least one linear motor as described above, conveying the linear motor into the borehole, and operating a well tool by activating the linear motor.
