Abstract: A subterranean screen system features openings in a base pipe and sleeve sections of a porous material that preferably swells in the borehole to span an annular space around the base pipe. Retainers are mounted to the base pipe in a desired location and mechanically fixated using an internal grip system actuated through the wall of the retainer. A wedging action of slip segments is initiated by an angularly advancing assembly through the wall of the retainer. The retainer can have end rings extending past one or both ends over which the screen sleeve extends. Flat or ridges on the exterior of the retainer or end rings make assembly easier with hand tools to allow for rapid field assembly, if needed. Filtration occurs through the sleeves that abut the borehole wall and into the base pipe openings and to the surface.

Abstract: A downhole tubular scraper is run in on slickline with an on board power supply. It features counter-rotating scrapers without an anchor in one embodiment or an anchor with single rotating scrapers. The scraper is selectively operated to conserve power in the power supply. A drive system uses a single driver to obtain counter-rotating motion in the scrapers.

Abstract: A grapple device is secured to a mill to allow relative rotation between them. The grapple has an outward bias to allow it to grip the packer bore or an extension from the packer. The mandrel has a wedge adjacent its lower end and torque fingers that fit between grapple segments when relative longitudinal movement occurs between the mandrel and the grapple assembly. The grapple assembly has a left hand thread so that it comes out of the packer if the mandrel engages the grapple assembly in a manner for tandem rotation. The torque fingers on the wedge on the mandrel support the grapple fingers over their length as rotation to the right removes the grapple assembly from the packer bore. Reverse circulation takes away the cuttings into the mill bore where they are separated from the reverse circulating fluid.

Abstract: A through tubing centralizer is delivered below the tubing and expanded against a surrounding tubular for fixation. In a window milling through tubing application, a whipstock is delivered through tubing and anchored. One or more centralizers are then delivered through tubing and expanded so that their inside diameter when set exceeds their outside diameter during run in. They are placed below the tubing and above the whipstock to help a through tubing mill stay on the whipstock ramp while milling the window. After the window is started, the centralizer can be expanded fully against the surrounding tubular to allow subsequent removal of the whipstock. Optionally, the centralizer can be collapsed for removal through tubing.

Abstract: A flow sensor is incorporated into a junk basket to sense a flow stoppage due to a plugged screen or plugged cuttings ports in a mill. The sensor triggers a signal to the surface to warn personnel that a problem exists before the equipment is damaged. The sensor signal to the surface can take a variety of forms including mud pulses, a detectable pressure buildup at the surface, electromagnetic energy, electrical signal on hard wire or radio signals in a wifi system to name a few options. Surface personnel can interrupt the signal to take corrective action that generally involves pulling out of the hole or reverse circulating to try to clear the screen or mill cuttings inlets. Other variables can be measured such as the volume or weight or rate of change of either and a signal can be sent to the surface corresponding to one of those variables to allow them to be detected at the surface in near real time.

Abstract: A release mechanism for a downhole tool is actuated by radial movement of a locking member. The locking member provided as much as full circumferential support in the locked position and once released can be prevented from re-gripping the previously connected elements. Illustrative examples of the mechanism for radial movement for release comprise sleeves that expand and radially oriented pistons. Shear pins or collets are not used to hold the components together in the preferred embodiment. Internal pressure fluctuations before initiating the release sequence will not cause unwanted release. The mechanism is applicable to a variety of downhole tools and is illustrated in the context of a hydraulic release.
