To perform an aligned operation downhole, a tubular disposed downhole has an internal bore with a first inner circumference and has a target at a first radial orientation. A locator profile is defined about the internal bore at a first location, and an internal nipple is defined about the internal bore at a second location. The internal nipple has a second inner circumference less than the first of the internal bore. An orientation slot is defined longitudinally across the internal nipple and is disposed at a second radial orientation configured relative to the first radial orientation of the target. A tool is deployable into the internal bore. The tool has a locator to engage in the locator profile and has an orientation key to engage in the slot and align an operational component for the aligned operation with the target.

Assembly and method for performing aligned operation with tool oriented in downhole tubular

Apparatus if provided for use in wells, particularly wells that have high-pressure and high-temperature conditions in the well. The shells of completion equipment that is required to withstand the rigorous conditions in such wells are increased in strength by laminate layers that are formed of materials having higher yield strength than the yield strength of materials that can be used in well fluids.

Laminate pressure containing body for a well tool

A kit for converting an existing wireline retrievable surface controlled subsurface safety valve () into a bypass passageway apparatus () allowing the injection of production-enhancing fluid into a wellbore while maintaining the operation of the closure member (). Bypass passageway () can extend between upper () and lower () adapters external to the existing wireline retrievable surface controlled subsurface safety valve () to allow fluid injection bypass thereof. Conversion kit can include a tubing string hanger to suspend a velocity tubing string (), a gas lift valve () for gas lift operations, a locking mandrel (), and/or a spacer tube ().

Method and apparatus for continuously injecting fluid in a wellbore while maintaining safety valve operation

Multiple ball launch assemblies comprise a plurality of ball launch pods disposed around an outer wall surface of a housing. The ball launch pods are operatively associated with a flow tube disposed within the housing. An actuator assembly rotates the flow tube to align a first opening in the flow tube with a first ball launch pod so that a first ball is launched into the wellbore. Further rotation of the flow tube aligns subsequent openings in the flow tube with subsequent corresponding ball launch pods so that subsequent balls are launched into the wellbore.

Multiple ball launch assemblies and methods of launching multiple balls into a wellbore

The present invention is directed to a method and apparatus for providing a pathway for fluid communication through a tubing-retrievable subsurface safety valve (TRSSV). The method and apparatus are designed to be deployed within a hydrocarbon wellbore after the TRSSV has failed. The apparatus is a milling tool that is run into the wellbore and landed within the TRSSV. The milling tool comprises a housing system, a cutting system, a drive system, and an actuating system. In operation, the milling tool is landed within the housing of the TRSSV. Thereafter, the actuating system is initiated. The actuating system actuates the drive system, which in turn drives the cutting system. In one arrangement, the cutting system includes blades for shaving the pressure containing body of the TRSSV, thereby forming a pathway for fluid communication between a hydraulic fluid line and a bore of the safety valve.

Downhole milling machine and method of use

A valve for use in a wellbore, the valve having a compensating secondary sealing system for misalignments that inevitably occur in sealing subsurface valves, particularly subsurface safety valves. A sealing system can include a dynamic sealing system and a static sealing system, where the static sealing system establishes one or more line contact surfaces. The line contact surfaces can be leading, in that the forward edge of the seal faces a corresponding engagement portion of the actuator. The actuator can include at least two spherical engagement portions where one of the spherical engagement portions engages resilient and non-resilient seals with line contact surfaces on a downstroke and the other spherical engagement portion engages resilient and non-resilient seals with line contact surfaces on an upstroke. Further, a bearing disposed above seals on a piston of the actuator assists in keeping contaminants out of the seal area of the piston.
