Abstract: A frustoconical member includes a metal composite that has a cellular nanomatrix comprising a metallic nanomatrix material; a metal matrix disposed in the cellular nanomatrix; and a first frustoconical portion. A process of making the frustoconical member includes combining a metal matrix powder, a disintegration agent, and metal nanomatrix material to form a composition; compacting the composition to form a compacted composition; sintering the compacted composition; and pressing the sintered composition to form the frustoconical member having a tapered portion on an outer surface of the frustoconical member. The frustoconical member can be used by contacting a frustoconical portion of the frustoconical member to a tapered surface of an article; applying pressure to the frustoconical member; urging the frustoconical member in a direction relative to the article to expand a radial dimension of the article; and contacting the frustoconical member with a fluid to disintegrate the frustoconical member.

Abstract: Wiper plugs or other shapes are made from shape memory foam in a size large enough to wipe or clean a tubular of a predetermined size. The plug or other shape is then reformed to a smaller dimension above its transition temperature and allowed to cool while holding that shape. The smaller shape allows delivery through a running string that is smaller than the tubular string to be wiped. Preferably before reaching the string to be wiped, the trigger is applied to get the wiper or other shape above its transition temperature where it then reverts to the prior larger dimension for effective wiping of the string that it will next pass through. The trigger can be well fluid temperature or composition, applied heat from the tubular, generated heat within the wiper or other shape, or heat released from agents introduced into the well acting alone or in conjunction with well fluids.

Abstract: In a completion for producing methane the bottom hole assembly has a base pipe with porous media surrounding it for equalizing flow along the base pipe. A shape memory polymer foam surrounds the porous media. The borehole can be reamed to reduce produced methane velocities. Surrounding the shape memory polymer is an exterior layer of consolidated proppant or sand that can self-adhere and/or stick to the polymer foam. The proppant or sand can be circulated or squeezed into position although, circulation is preferred. The borehole may enlarge due to shifting sands in an unconsolidated formation as the methane is produced. The bottom hole assembly helps in fluid flow equalization and protects the foam and layers below from high fluid velocities during production.

Abstract: In producing methane a bottom hole assembly the borehole may enlarge due to shifting sands in an unconsolidated formation as the methane is produced. The enlargement of the borehole can be sensed in real time such as by using a fiber optic cable. In response to such information parts of the bottom hole assembly near the washout can be isolated or the bottom hole assembly in the vicinity of the washout can be fortified with inserts from the surface to minimize damage from erosion caused by higher velocities resulting from borehole washouts.

Abstract: A fracturing operation is done in open hole without annular space isolation. The annular space is spanned by telescoping members that are located behind isolation valves. A given bank of telescoping members can be uncovered and the telescoping members extended to span the annular space and engage the formation in a sealing manner. Pressurized fracturing fluid can be pumped through the telescoped passages and the portion of the desired formation fractured. In a proper formation, cementing is not needed to maintain wellbore integrity. The telescoping members can optionally have screens. Normally, the nature of the formation is such that gravel packing is also not required. A production string can be inserted into the string with the telescoping devices and the formation portions of interest can be produced through the selectively exposed telescoping members.

The inflow control device may have a flow coupler configured to provide selective fluid communication with the at least one port.

Abstract: Systems and methods for distributed downhole sensing in which a polymeric sensor system is coupled to one or more pieces of downhole equipment. The polymeric sensor system has multiple electric or nano sensors embedded in a polymeric material such as a tape that can be applied to the downhole equipment to sense parameters at multiple, physically distributed locations. A monitoring unit at the surface of the well may receive data from the embedded sensors. A control unit at the surface of the well may communicate control information through the polymeric sensor system to electrically controlled equipment downhole, eliminating the need for a control line that is separate from the polymeric sensor system.

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.
