Abstract: An inflatable packer assembly features a pump and a piping network configurable to add fluid or remove fluid from the inflatable. Sensor can detect borehole variables and transmit readings to a remote location. Commands can be sent from the remote location to a borehole controller to configure the piping system for addition or removal of fluid from the inflatable to a desired level. A power source can power the pump and automatic valves to configure the system for addition or removal of fluid. Control from a remote location can be manual or automatic based on algorithms loaded on a processor that can be remotely locally located by the inflatable. A reservoir with clean fluid that is in pressure balance with borehole fluids can be used with a fluid separation device between clean and well fluids. Well fluids can be screened before being delivered to the inflatable.

Abstract: In a plug an abandon environment with casing and a tubular string running through the casing a tool is placed at a desired location for a severing of the inner tubular. A first set of blades is extended from a housing to cut radially until the inner tubular is severed. A second set of blades are then extended for axial milling with a reach limit of the outside wall of the severed tubular at a location between upsets. As the axial milling reaches an upset, the second set of blades is allowed to retract and a third set with a longer reach is extended to axially mill the upset. Thereafter the third set of blades is allowed to retract and the second set is extended to continue axial milling. The second and third sets of blades can be reversed so that initial axial milling can be at the upset rather than between the upsets followed by milling between the upsets with the shorter reach blades.

Abstract: A clamp device that attaches an umbilical to a drill string incorporates a junk basket. The basket is notched to accept the umbilical and an insert piece is slipped into the notch after the umbilical is properly in position. The insert piece straddles the umbilical and is secured the balance of the basket to complete the basket. The basket can be slipped over the drill pipe and either secured directly to the outer surface of the drill pipe or against a support member that is supported off the drill pipe. One or more of such baskets can be used and they can also function as umbilical clamps. The basket can also be vertically split to allow mounting it over the drill pipe and umbilical without having to slip it over an end of the drill pipe as the drill pipe is tripped into or out of the hole.

Abstract: In some embodiments, apparatus useful for cleaning at least part of the interior surface of a generally cylindrically-shaped member disposed in a subterranean well includes a housing and a plurality of retractable mill blades supported on the housing and movable from an initial retracted position to an extended position and thereafter to a final retracted position.

Abstract: In some embodiments, apparatus useful for cleaning at least part of the interior surface of a cylindrically-shaped member disposed in a subterranean well includes a housing and a plurality of retractable mill blades supported on the housing. The mill blades of such embodiments are capable of cleaning the entire circumference of the interior surface of at least a portion of the cylindrically-shaped member upon reciprocation of the housing.
