Abstract: A wellbore tubular patch for patching a hole in a wellbore has been invented, the tubular patch in certain aspects having an expandable top member having a hollow tubular body and a top end and a bottom end, an expandable bottom member having a hollow tubular body and a top end and a bottom end, an expandable outer sleeve in which is secured a portion of the bottom end of the expandable top member, and a portion of the top end of the expandable bottom member inserted into and held within expandable outer sleeve. A method for making a tubular patch for patching a hole in a tubular in an earth wellbore has been invented, the method in certain aspects including securing a portion of a bottom end of an expandable top member in an expandable outer sleeve, the expandable top member having a hollow tubular body and a top end, and securing a portion of a top end of an expandable bottom member within the expandable outer sleeve, the expandable bottom emmber having a hollow tubular body.

Abstract: A stroke indicator has been invented for indicating that a movable inner member of an hydraulically activated wellbore tool or apparatus has moved, particularly that movement of such a member indicating that a stroke of the tool or apparatus has occurred. In one aspect such an indicator is used to indicate that the stroke of a wellbore tubular patch expander system has been completed. A tubular patch has been invented which includes two or more connected tubular patch members. A tubular patch system has been invented for patching operations which, in one aspect, is useful as a "through tubing" tubular patch system and has a body and a series of selectively expandable members which, once having passed through a tubular of a first diameter, are expandable in a tubular of a second diameter larger than the first diameter and then operable to expand a liner patch to seal a leak in the tubular of the second diameter.

Abstract: A packer mill system for milling a packer in a wellbore has been invented which has, in certain aspects, a bushing with a hollow generally cylindrically shaped bushing body with a bottom, a top, a bushing bore extending therethrough from top to bottom, and at least one key on an interior surface thereof, the at least one key projecting inwardly into the bushing bore, a mandrel initially disposable within the bushing, the mandrel having a hollow generally cylindrically shaped mandrel body with a top, a bottom, a mandrel bore extending therethrough from top to bottom, and a slot system formed in an exterior surface of the mandrel body, the at least one key disposed for movement through the slot system, engagement apparatus connected to the bottom of the mandrel body for engaging the packer, milling apparatus connected to the bottom of the bushing body and disposed for movement therethrough of the engagement apparatus, the slot system having a series of one or more interconnected slots through which the at least

Abstract: A downhole tool for making up threaded connections between lower and upper tubulars within a well bore includes a lower anchoring member, an upper anchoring member, and a drive member including a movable piston assembly. A plurality of straight splines on the piston assembly and mating splines on a housing rotatable with the lower anchoring member allow axial movement while preventing rotational movement of the piston assembly with respect to the lower anchoring member during the tool driving stroke. The helical drive component on the piston assembly and a mating driven component rotatable with the upper anchoring member cooperate to rotate the upper anchoring member and thus the upper tubular to make up the downhole threaded connection. According to the method of the present invention, the upper and lower anchoring members are each secured to a respective tubular, and fluid pressure is increased to drive the piston assembly downward, thereby rotating the upper tubular.
