Abstract: A bypass tool has a piston movable within the bore of a central housing. A control slot on an exterior wall of the piston engages a slot pin in the housing. Longitudinal movement of the piston is downward, in response to fluid pressure exerted on a ball seated on a ball seat on the piston; and spring biased upward. The control slot and slot pin rotate the piston as it moves longitudinally between a first, upper position in which bypass ports in the housing are closed, and a second, lower position in which the bypass ports are open. An intermediate longitudinal position has the ports closed, and permits pressuring up on a ball to force it through the ball seat and reset the tool in the flow through position. The ball and/or ball seat may be of resilient material to permit passage of the ball through the seat.

Abstract: A downhole separation apparatus for releasing a pipe string from a bottom hole assembly is disclosed. The apparatus has a tubular collet body, a tubular bottom sub, and a piston collet positioned within the collet body. The collet piston has a plurality of collet fingers threadedly engaging an internal profile of the bottom sub. Separation is accomplished by pumping a circulation ball through the pipe string until it lands on a ball seat inside the collet piston. Increasing fluid pressure then shifts the piston collet axially downward within the collet body thereby causing the collet fingers to collapse to disengage the bottom hole assembly from the pipe string.

Abstract: A wellbore underreamer has a tubular body, a central body cavity, and pivotally mounted blades in slots on the periphery of the tubular body. A translatable piston in the central body cavity is urged away from cam surfaces on the blades by a biasing spring. The piston has an orifice restricted fluid passage and translates in response to fluid pressure determined by the selected piston orifice and biasing spring. Fluid circulates through the piston fluid passage and fluid passages in the underreamer while piston movement is restrained by the spring. At a predetermined fluid pressure, the piston moves to engage the blade cam surfaces to pivotally extend the blades outward from the blade slots. The blades are held in the slots by a spring biased ball until they are extended by the piston.

Abstract: A mechanically activated bypass valve apparatus for allowing fluid being pumped through the pipe or coiled tubing string to be bypassed around a tool string and into the wellbore. Activation of the bypass valve is accomplished by applying weight-on-bit to the apparatus to shear a set of shear screws, allowing the mandrel to move axially relative to the tubular housing. Lowering the pipe string and setting down weigh on bit misaligns fluid bypass ports in the mandrel and housing, thus forcing fluid to continue to flow through the bore of the tool and to the toolstring below the bypass tool. Picking up on the pipe string aligns corresponding ports in the mandrel and housing and allows fluid to flow from the bore of the tool to the wellbore annulus, thus bypassing other tools downhole of the apparatus.

Abstract: A downhole motor for drilling and servicing of wells has an elongated outer housing and an elongated mandrel rotatably disposed within the housing. A primary thrust bearing is disposed between the lower end of the housing and the mandrel, and transfers axial loads downward from the housing to the mandrel, and then to the drill bit or other tool mounted on the lowermost end of the mandrel. The placement of the primary thrust bearing permits it to extend radially to the outer diameter of the housing. One preferred embodiment of the primary thrust bearing comprises bearing surfaces of polycrystalline diamond compact (“PDC”) material.

Abstract: A safety separation apparatus for use on a workstring disposed in a wellbore is comprised of a tubular upper member attached to the workstring, a tubular bottom member attached to a DTA, and a translatable tubular piston positioned within the tubular upper member and tubular bottom member of the safety separation apparatus. The tubular upper member has upper member fingers threadedly engaged with threads within the interior surface of the tubular bottom member. The tubular piston has a seat surface where a release ball may be seated and a plurality of collapsible piston fingers engaged with a piston finger groove within the tubular bottom member. Fluid pressure on the release ball inserted in the tubular piston will translate the tubular piston to collapse the piston fingers for disengagement of the bottom member and the attached DTA from the upper member and the attached workstring.

Abstract: A hydraulic percussive apparatus is disclosed for generating vibrating forces to a pipe string. The apparatus is attached to the pipe string a central bore through which fluid may be introduced into the apparatus. The apparatus has a tubular housing, an anvil surface with an irregularly profiled surface, and a rotor with an irregularly profiled hammer surface that is urged to move axially toward and away from the anvil surface. The rotor has a longitudinally extending fluid bore and a tangentially oriented fluid port in communication with the longitudinal fluid bore of the rotor. Fluid entering the rotor's fluid bore and exiting the rotor's tangentially oriented fluid port rotates the rotor, and thus the irregularly profiled hammer surface on the irregularly profiled anvil surface, moving the hammer surface toward and away from the anvil producing intermittent impact forces.

Abstract: An apparatus for dampening vibrations in a drill string has a tubular housing with an upper sub connected to a first end, having a threaded connection for engagement with the pipe or drillstring. A piston is positioned in the bore of the tubular housing and longitudinally movable in the bore; the dimensions of the piston and bore permit limited fluid flow around the piston.Connected to the piston and extending out of the second end of the housing is a bottom sub. Mating and engaging profiles in the tubular housing and lower sub allow longitudinal movement between them, but no relative rotation. A spring member, which may be a mechanical spring, an elastomeric member, a compressed gas, or some combination thereof, biases the piston and lower sub out of the tubular housing.
