Abstract: A packer system includes a retainer positionable adjacent to a packing element and coupleable to a cylinder of a downhole tool in a wellbore. The retainer is moveable in a first direction along a mandrel of the downhole tool to compress the packing element to a compressed state and generate a seal in the wellbore or to set a slip in response to an applied pressure. The packer system includes a piston moveable in a second direction along the mandrel and configured to compress a spring in response to the applied pressure. The packer system includes an interfacing element configured to couple the cylinder to the piston subsequent to the cylinder moving a predefined amount. The packer system includes a ratchet mechanism configured to prevent movement of the cylinder in the second direction.

Abstract: The disclosure provides a mechanism for setting a packer. The mechanism comprises a piston disposed within a port of a packer mandrel, wherein the port comprises a seat operable to receive the piston. The mechanism further comprises a first chamber disposed at a first end of the piston, wherein the first chamber is sealed and comprises atmospheric pressure. The mechanism further comprises a spring disposed at a second end of the piston. The mechanism further comprises a second chamber disposed at the second end of the piston, wherein the second chamber comprises atmospheric pressure.

Abstract: Provided is a patch for a fluid line, a system employing a fluid line, and a method for sealing a fluid line. The fluid line, in one aspect, includes a tubular, and a sleeve of expandable metal positioned about the tubular, the sleeve of expandable metal comprising a metal configured to expand in response to hydrolysis and thereby seal a leaking section of a fluid line.

Abstract: A well tool in one or more example comprises a packer and a setting tool having a through bore in fluid communication with the tubular conveyance. An actuation port fluidically couples the through bore to a setting chamber. Pressurized fluid may be supplied to the setting chamber via the through bore to set the packer. An expandable material may then be exposed to an activation fluid to seal off the actuation port and isolate the setting chamber. By isolating the setting chamber after setting the sealing element, pressure may be increased to above the setting pressure to perform a well service operation, without damaging the setting chamber.

Abstract: Provided is a sealing/anchoring element, a sealing/anchoring tool, and a method for sealing/anchoring within a wellbore. The sealing/anchoring element, in one aspect, includes a circlet having an inside surface having an inside diameter (di), an outside surface having an outside diameter (do), a width (w), and a wall thickness (t). In one aspect, the circlet has one or more geometric features that allow it to elasto/plastically deform when moved from a radially reduced state to a radially enlarged state, and the circlet comprises an expandable metal configured to expand in response to hydrolysis.

Abstract: An apparatus and method for repairing broken, compromised, damaged or cracked conduits is provided. Conduits such as pipes and tubing may bear fluid flows therethrough. Often these conduits are damaged or compromised and begin leaking fluid. A clamp is provided that holds expandable metal securely about the outer circumference of the conduit. The expandable metal may react with any leaking fluid, such as water, thereby expanding and sealing the crack or otherwise seals the compromised conduit in a permanent manner.

The fluid line, in one aspect, includes a tubular, and a sleeve of expandable metal positioned about the tubular, the sleeve of expandable metal comprising a metal configured to expand in response to hydrolysis and thereby seal a leaking section of a fluid line.

Abstract: Provided is a seal assembly. The seal assembly, in one aspect, includes a first member, the first member formed of a first material, and a second member overlapping with the first member, the second member formed of a second material, the first and second members defining an overlapping fluid leakage path. The seal assembly according to this aspect further includes a primary seal positioned in the overlapping fluid leakage path, the primary seal configured to prevent fluid from passing from a first side of the overlapping fluid leakage path to a second side of the overlapping fluid leakage path. The seal assembly according to this aspect additionally includes an expandable metal backup seal positioned in the second side of the overlapping fluid leakage path, the expandable metal backup seal including a metal configured to expand in response to hydrolysis.

Abstract: Provided is a slip ring for use with a sealing assembly, a sealing tool, and a method for sealing an annulus within a wellbore. The slip ring, in at least one aspect, includes an expandable metal ring member having a width (w), a wall thickness (t), an inside diameter (di) and an outside diameter (do), the expandable metal ring member comprising a metal configured to expand in response to hydrolysis. The slip ring, in at least one aspect, further includes one or more cuts located in the wall thickness (t) and spaced around a circumference of the expandable metal ring member, the one or more cuts configured to allow the expandable metal ring member to move between a radially reduced state and a radially enlarged state.

Abstract: A packer assembly for use within a borehole. The packer assembly may include a mandrel, a top packer retainer, a packer, a bottom packer retainer, and a sleeve. The top packer may extend circumferentially around the mandrel. The packer may extend circumferentially around the mandrel and may be positioned downhole of the top packer retainer. The bottom packer retainer may extend circumferentially around the mandrel and may be positioned downhole of the top packer retainer. The bottom packer retainer may be shiftable to compress the packer against the top packer retainer to expand and set the packer. The packer sleeve may be shiftable between a run-in position covering the packer and a retracted position uphole of the packer, and the packer sleeve may restrict the packer from expanding when in the run-in position.

Abstract: Systems, methods, and apparatuses for accommodating thermal expansion in a tool string are disclosed. Exemplary systems include one or more sacrificial members placed between or adjacent elements of the tool string that are expected to expand when subjected to high temperatures. The sacrificial members are configured to destruct upon exposure to a control signal or a critical temperature or load. Destruction of the sacrificial members provides additional clearance for adjacent elements to expand.

Abstract: An external slip includes a slip body comprising a wall having internal and external surfaces. The internal surface includes a ramp portion, and a plurality of teeth is disposed on the external surface of the wall of the slip body. A plurality of expansion slots extends through a thickness of the wall, at least one extending from a first end of the wall toward a second end of the wall but not reaching the second end.
