Abstract: In aspects, the present disclosure provides a method of performing a wellbore operation, which in one embodiment includes supplying a mixture containing a fluid and shape memory particles of a first size into a selected region in the wellbore, retaining the shape memory particles of the first size in the selected region while expelling the fluid from the selected region, and activating the shape memory particles retained in the selected region to cause them to expand to attain a second shape to fill the selected region with shape memory particles having the second shape.

Abstract: A downhole apparatus positionable along a pipe string in a wellbore. The apparatus including a tubular structure having an outermost diameter greater than an outer diameter of an adjacent portion of the pipe string. A first end face facing a flow path in the wellbore, and at least one indentation or protuberance provided on an outer surface of the tubular structure. The at least one indentation or protuberance arranged to cause particulates in slurry within the flow path to collect and remain in a vicinity of the tubular structure. A method of diverting fracturing treatments in a wellbore is also included.

Abstract: A space filler material is used to prevent accumulation of debris that could later foul the operation of adjacent moving parts. In one application a void space that is subsequently closed by actuated parts is initially filled with a material that is highly compressible and has voids that allow it to compress without undue resistance to part movement when the void volume is reduced. Ideally, the pores or voids in the material itself are small enough to keep most if not all the debris from entering and making the space filling material too rigid to collapse under part movement. In an alternative application, the material can be in an annular space such as a seal bore and it can keep debris from getting past the seal bore while allowing hydrostatic pressure across itself thereby helping it to maintain its position until moved such as by shifting of an inner string to which it is attached.

Abstract: The removable plug features a solid material that is housed in a porous container that has its shape changed to transition from the run in shape to the set shape. A swage is moved through a passage in the container to enlarge the passage and move the container to a borehole wall. The passage is then closed such as with a flapper valve or by moving in a mandrel into the expanded passage and lodging the mandrel in the expanded passage. Various release techniques are described.

Abstract: The removable plug features a solid material that is housed in a porous container that has its shape changed to transition from the run in shape to the set shape. A running string and setting tool that creates relative movement deliver the plug and pull on its lower end while holding the top stationary against a backing plate. The container is pulled into itself as the radial dimension grows for the set. There can be a mandrel that remains in position and can lock to the backing plate or alternatively there can be no mandrel or a removable mandrel. The porous container can be removed in a variety of ways to let the solid material escape to be removed with fluid circulating in the wellbore. Alternatively the mandrel can be undermined to let the solid material escape for recovery.

Abstract: A deformation system, including a deformable member and a tool operatively arranged to deform the member due to actuation of the tool from a first set of dimensions at which the deformable member is positionable with respect to a structure to a second set of dimensions at which the deformable member engages with the structure. The tool at least partially comprises a disintegrable material responsive to a selected fluid. A method of operating a deformation system is also included.

Abstract: An apparatus positionable along a downhole string. The apparatus includes a flexible structure retained on a surface of the string in a first condition. The flexible structure movable by a flow to substantially fill an annular space between the string and a radially positioned structure in a second condition. A method of diverting fracturing treatments in a wellbore is also included.

Abstract: Nanoparticle-treated substrates, such as screens, sand beds or proppant beds, may effectively filter and purify fluids such as waste water or fluids produced from a formation, as well as other liquids. When tiny contaminant particles in a fluid such as waste water flow contact the nanoparticle-treated substrate, the nanoparticles will capture and hold the tiny contaminant particles on the substrate due to the nanoparticles' surface forces, including, but not necessarily limited to van der Waals and electrostatic forces or other associative forces. Coating agents such as alcohols, glycols, polyols, vegetable oil, and mineral oils may help apply the nanoparticles to the surfaces of structures in the filter beds or packs.

Abstract: A frac plug mandrel assembly has an inner core that permits flow that is surrounded by a thin wall tube that distributes compressive loading, such as that applied by the set sealing element to the core. The core is a cylindrically shaped insert for inside the tube and allows flow until a ball or plug is landed on a seat to close off the flow through the core. The core can have a star pattern with a series of radially extending segments from a solid hub or a cylindrical shape of a honeycomb or other porous structure that has the requisite strength to resist collapse from compressive loading of the set sealing element while still allowing sufficient flow area for fluid displacement.

Abstract: In aspects, the disclosure provides an apparatus that may include a member having fluid flow passages and a filter member placed proximate the member with the fluid flow passages, the filter member including an array of three-dimensional elements configured to inhibit flow of solid particles of a selected size when a fluid containing such solid particles flows from the filter member to the member with the fluid flow passages.

Abstract: An extrusion barrier assembly for high pressure and temperature applications for a sealing element incorporates a backing member between the sealing element and a multi-row petal type backup ring assembly. The surface irregularities of the offset petals are distributed through the backing member so that stress concentration locations at the petal transitions between rows are diffused through the backing member to avoid or minimize the tendency of the petals to stress crack at row to row transitions. The backing member is formed from spirally wound strip of sheet material that can be coated to promote relative sliding of overlapping layers. The assembly can be temporarily bonded to retain its shape with adhesive that releases under expected well conditions when the packer or bridge plug is set.

Abstract: A well that has a plurality of sliding sleeves used to originally fracture multiple zones with balls of increasing size dropped on balls seats to sequentially open ports for fracturing in a direction toward the well surface is refractured. The method involves using a bottom hole assembly (BHA) that has a fluid motor driven mill that mills out ball seats and has with it a ported sub and a resettable packer. Once the lowermost ball seat is milled out a ball is dropped into the BHA to isolate the fluid motor and open a ported sub below a resettable packer. The dropped ball also enables a collet to latch an open sleeve to give a surface signal that the BHA is located properly for packer deployment so that the refracturing can begin through the coiled tubing string that can support the BHA or in a surrounding annular space.
