摘要： A method of forming an entry guide at an end of a tubular string in a wellbore can include conveying a forming device into the wellbore, and deforming the end of the tubular string from a cylindrical shape to an outwardly widening shape with the forming device. A method of forming an entry guide at an end of an expanded liner hanger in a wellbore can include outwardly expanding the liner hanger, thereby sealingly securing a tubular string in the wellbore, and deforming the end of the liner hanger from a cylindrical shape to an outwardly widening shape with a forming device.

摘要： A setting tool for an expandable liner hanger. A method includes the steps of: releasably securing the setting tool to the hanger, the setting tool including an expansion cone for displacing through the hanger; and conveying the setting tool and hanger into the well on a generally tubular work string while no portion of the hanger extends longitudinally between the expansion cone and the work string. A setting tool includes an expansion cone, which is displaceable through the liner hanger to expand the hanger; at least one piston positioned on one side of the expansion cone; and an anchoring device for releasably securing the setting tool to the liner hanger, the anchoring device being positioned on an opposite side of the expansion cone. The expansion cone is pressure balanced between its two sides when the expansion cone is displaced through the liner hanger.

摘要： A downhole tool (100) for wellbore operations comprises a substantially tubular member (130) that is operably positionable in the wellbore and a rotation member (110) that is rotatably disposed within the substantially tubular member (130). The rotation member (110) has a passageway (112) through which objects may pass into the wellbore. The rotation member (110) rotates about an axis of rotation (x) that is substantially perpendicular to the longitudinal axis (y) of the substantially tubular member (130) in response to fluid flow through the passageway (112). The rotation member (110) has magnetic properties such that rotation of the rotation member (110) generates a magnetic field that produces useable power.

摘要： A power generating system (100) for a downhole operation (10) having production tubing (40) in a wellbore (12) includes a magnetized rotation member (110) coupled to the wellbore (12) within the production tubing (40), the rotation member (110) having a passageway (112) through which objects, such as tools, may be passed within the production tubing (40). Support braces (170, 172) couple the rotation member (110) to the production tubing (40) and allow the rotation member (110) to rotate within the production tubing (40). Magnetic pickups (150, 152) are predisposed about the rotation member (110) within the wellbore (12) and a power conditioner (200) is provided to receive currents from the magnetic pickups (150, 152) for storage and future use. The rotation member (110) rotates due to the flow of fluid, such as crude oil, through the production tubing (40) which causes the rotation member (110) to rotate and induce a magnetic field on the magnetic pickups (150, 152) such that electrical energy is transmitted to the power conditioner (200), the power conditioner able to store, rectify, and deliver power to any one of several electronic components within the wellbore (12).

摘要： A wireline set baffle for positioning in a well casing after the well casing has already been placed in a wellbore. The apparatus comprises a baffle and a setting or running tool engaged with the baffle and adapted for positioning the baffle at a predetermined location in the wellbore. In one embodiment, a lock ring may be used to lock the baffle to the casing at a predetermined location, and in another embodiment, collet fingers on the baffle may be used to engage the casing. The lock ring may be initially held in a non-engaging position by a lock ring retainer or shear pins. The collet fingers may be initially held in a non-engaging position by a cover which is disengaged from the collet fingers by a blasting cap. Engagement may be with an inner surface of the casing or a recess defined at a casing joint. A method of using the wireline set baffle is also disclosed.

摘要： A tie back receptacle extension includes a stinger having a smooth bore latch assembly carried thereon which includes a wedge device and a ramp, and the ramp outwardly displaces the wedge device to secure the stinger within a substantially smooth bore. A smoothbore latch assembly includes a spiral wound spring received in a recess, and the recess and the spring extending circumferentially relative to a stinger. A ramp outwardly displaces the spring relative to the recess in response to displacement of the spring relative to the ramp. A method of securing a stinger within a substantially smooth bore includes: providing a latch assembly on the stinger; inserting the stinger into the bore; and engaging the latch assembly with the bore, thereby securing the stinger relative to the bore, without the latch assembly engaging any recess formed in the bore.
