  • Publication number: 20140124199
    Abstract: A tubular assembly is disclosed for use in a wellbore (5) of an oil, gas or water well, typically for landing a downhole device in the wellbore. The assembly has a sleeve (1) adapted to receive the body of the downhole device. The sleeve is deployed into a conduit in the wellbore and expanded, so that the outer circumferential surface of the sleeve is radially expanded against the inner surface of the conduit. The sleeve has a bore with an inner circumferential surface comprising an inwardly facing formation adapted to engage with an outwardly facing formation on the body of the downhole device when the body of the downhole device is disposed in the bore of the sleeve. The sleeve is typically deployed in the wellbore at the desired location and is radially expanded by an expander device (2) that is deployed within the bore of the sleeve. The expanded sleeve plastically deforms and retains its expanded configuration after the radial expansion force is removed from the sleeve.

  • Publication number: 20140096947
    Abstract: A cutting and pulling tool has a piston responsive to flow therethrough with an orifice to create backpressure to drive the piston uphole to rotate the blades outwardly such as in an expanded section of tubular below a transition from a smaller tubular dimension. The extended cutters are pulled to the transition and an overpull determines that the desired location has been reached. The overpull force is removed and fluid flow and rotation is commenced to cut. The blades extend to a position perpendicular to the tool axis so that they are supported off a radial housing surface as the weight of the cut string above is supported on the blades. The string is pulled up and supported with slips on a rig floor at which point weight is slacked off and a plug is landed in the top of the piston to push it down to remove the tool.

  • Publication number: 20140060838
    Abstract: The invention relates to the completion and enhancement of oil and gas wells. The invention provides for a downhole tool which: enters vertical or horizontal wells located adjacent to the oil and gas bearing formation, parts the casing and extends outward forming micro-boreholes necessary to remove residual oil and gas which remain in place. After the initial fluid production has been harvested, the invention can be employed on new or old wells and can operate in all conditions which wells encounter during the standard drilling process. The process of micro-holes can replace the process known as “fracking”. Fracking is being employed; however the process is being reviewed due to safety of human life. The invention employs special alloys and procedures to form the extended reach micro-boreholes.

    Abstract: A spearing device for use in removing casing is disclosed. The spearing device includes: a top sub; a bottom sub; a mandrel, coupled to the top and bottom subs, having an outer corrugated surface; a grapple having a correspondingly corrugated inner surface and an outer surface including wickers for engaging an interior surface of the casing; a piston disposed within the mandrel and operatively coupled to the grapple; and a spring operative with the piston and biasing the grapple toward a collapsed position. The grapple: (i) axially and rotationally moves along the corrugated outer surface of the mandrel and (ii) expands and collapses responsive to axial movement relative to the mandrel. Responsive to increases in hydraulic pressure, the piston compresses the spring and axially moves and expands the grapple. Responsive to subsequent decreases in hydraulic pressure, the spring decompresses and axially moves and collapses the grapple.
