Abstract: A method of activating an anchor with an anchor activation system including a housing having an outer surface and an inner surface defining an internal chamber includes introducing a first activation force to a trigger comprising a piston arranged in a piston cylinder extending radially through the outer surface to the internal chamber, sensing that the first activation force did not activate the anchor, and introducing a second activation force to the trigger without reconfiguring the anchor activation system to break a shear element retaining the piston with the first activation to release the piston and activate the anchor.

Abstract: An annular pressure activated downhole tool has a housing including an outer surface, an inner surface defining a passage, an annular projection projecting into the passage from the inner surface, and an opening. A mandrel extends into the passage. The mandrel has a first end and a second end. A power spring support is detachably connected to the second end of the mandrel in the passage. A power spring is arranged about the mandrel and extends between the power spring support and the annular projection. A trigger housing is arranged in one of the mandrel and the power spring support. A trigger arranged in the trigger housing selectively engages with the inner surface. The trigger is operable to disengage from the inner surface of the housing, releasing the power spring, and shifting the mandrel along the passage when exposed to a selected annular pressure.

Abstract: A method of performing a well bore operation in a well bore includes connecting a window mill to a whipstock connector forming a tubular section, supporting a tool below the whipstock connector, running the window mill, the whipstock connector, and the tool into the well bore, and axially loading the tool to perform the well bore operation.

Abstract: An anchor activation system including a housing having an outer surface, an inner surface defining an internal chamber, a first end, and a second end. A slip is shiftably mounted to the outer surface of the housing. The anchor activation system also includes a piston assembly and an activator mounted to the piston assembly. The activator selectively shifts the slip axially along the housing. A biasing member is arranged between the second end and the activator. A trigger is operable to selectively release the piston assembly.

Abstract: A window cutting system includes a window mill having a body including a connector member, a tip portion, and a plurality of blades arranged between the connector member and the tip portion. Each of the plurality of blades supports a plurality of cutting elements. A lug pocket is formed in at least one of the plurality of blades adjacent the plurality of cutting elements. A whipstock connector detachably coupled to the window mill. The whipstock connector including an outer surface and an inner surface, and at least one lug projecting radially inwardly from the inner surface. The at least one lug is selectively received by the lug pocket to connect the whipstock connector to the window mill.

Abstract: A one trip bottom hole assembly allows setting and testing a plug and release from the plug. Cement can be pumped onto the plug, after the BHA is raised, to an extent to meet local regulatory requirements. The cutter spear combination can be activated with pressure built on a second dropped ball larger than the first ball to release the blades for extension with fluid circulation. The circulation path through the spear is opened using pipe manipulation during the spear setting sequence. The cuttings from severing the tubular fall onto the cement. The spear is set with string manipulation as the drill string rotates the blades while maintaining the string under tension. The spear can be released and repositioned for the top of the string to facilitate removal and disassembly at the surface. All the above described operations are accomplished with a single trip into the hole.

Abstract: Systems facilitate forming lateral wellbores by optionally eliminating one or more trips downhole. The systems provide for forming a lateral wellbore by enabling the milling of a casing window and/or the drilling of the desired lateral wellbore to a target depth during a single trip down hole. The systems also facilitate improved downhole dynamics control and overall bottom hole assembly functionality.

Abstract: An apparatus and method for activating a downhole tool of a production system is disclosed. The apparatus includes a first component, a first magnetic member coupled to the first component, a second component of movable with respect to the first component, and a second magnetic member attached to the second component. The first component is generally stationary with respect a work string of the production system. An electric current activates at least one of the first magnetic member and the second magnetic member to create a magnetic force between the first magnetic member and the second magnetic member, thereby moving the movable component with respect to the stationary component to perform the action downhole. The produced motion of the movable component activates the downhole tool.
