Abstract: Apparatus and method comprising a plurality of particles which are magnetically attracted to one another in response to exposure to a magnetic field, and which maintain attraction to one another after removal of the magnetic field, the attraction being disabled when the particles are demagnetized, whereby the particles operate to alter the rheological properties of a fluid in which the particles are mixed when the attraction is enabled or disabled is disclosed.

Abstract: A field-responsive fluid which enters a semi-solid state in the presence of an energy field is improved by use of a plurality of energy field responsive particles which form chains in response to the energy field. The particles can be (a) composite particles in which at least one field-responsive member having a first density is attached to at least one member having a second density that is lower than the first density, (b) shaped particles in which at least one field-responsive member has one or more inclusions, and (c) combinations thereof. The particles improve the field-responsive fluid by reducing density without eliminating field-responsive properties which afford utility. Further, a multi-phase base fluid including a mixture of two or more substances, at least two of which are immiscible, may be used.

Abstract: A rubber pocket is described that is suitable for use on tubing, such as a packer-type seal, on casing, such as a cement-type seal, or on liners. The rubber pocket may contain cement particles, rubber particles, swellable particles, cement filled rubber particles, cement filled swellable particles, calcium oxide, magnesium oxide, magnesium sulfate, iron (III) oxide, calcium sulfoaluminate, clay, magnetic particles and/or reactants such as crosslinkers, retardants or epoxy. The particles may be bulk spheres, bulk fibers, hollow spheres, hollow fibers, etc. The rubber pocket or bladder may also be fully or partially filled with fluids such as polymer reactants. The pocket may also be empty or contain a small volume of reactants. The slurry or epoxy or other type of fluid and granular solid or injectable matter can be injected after the completion positioning downhole.

Abstract: Certain embodiments described herein are directed to silane functionalized fillers that may be, for example, covalently coupled to a polymer. In some examples, devices that include the filler reinforced polymer compositions are also described.

Abstract: Cross-linkers and polymers produced using them are provided. The cross-linked polymers are suitable for use in applications where a broad temperature range may be encountered. In some examples, at least a first and a second polyetheretherketone chain may be cross-linked to each other through two or more Schiff base linkages. Articles using the cross-linked polymers are also described.

Abstract: A high temperature downhole packer including a tubular member, an annular and longitudinally movable ring, and a packer. The tubular member has a stop located on an outer diameter thereof. The annular and longitudinally movable ring is disposed around the outer diameter of the tubular member. The packer element is disposed between the stop and the ring. The packer element includes a high temperature elastomeric polymer having a first storage modulus from about 1,000 MPa to about 10,000 MPa at a first temperature between about ?100° C. and about 175° C., and a second storage modulus from about 1 MPa to about 1000 MPa at a second temperature ranging from about 175° C. to about 475° C.

Abstract: An elastomeric composition for use in a borehole comprising a base polymer and a reinforcing reactive filler is disclosed. The elastomeric composition maintains flexibility before interaction and rigidity after interaction and therefore is suitable for use in downhole sealing systems.

Abstract: Systems and processes are provided for safely facilitating transfer of down-hole devices through an adaptive seal assembly capping a well under pressure. At least one dynamic seal is provided having a size and shape to accommodate varying cross section of an elongated down-hole device, such as a logging tool. The adaptive seal assembly includes a mating flange for coupling its open end to a reversibly sealable wellhead fixture. A pressure is maintained along a wellbore side of the reversible seal, while the aperture is varied according to the varying cross section of the down-hole device as it is translated along the axis. More than one dynamic seals can be actuated in a controlled sequence to apply axial thrust in a preferred direction to the tool. One or more robotic systems can be provided to further expedite manipulation of at least one of the tool and the vessel.

Abstract: A sol of metallic alkoxide is pumped into a desired location in a wellbore and allowed to gel, creating solids in-situ. The sol is either unstabilized, requiring rapid placement before gelling, or the sol is stabilized, permitting off-site mixing. Sols can be stabilized with either surfactant or with interfacial polymers. Large concentrations of surfactant can be placed in the sol to create templates around which gelation occurs, creating porous solids.

Abstract: An expandable structure for passive deployment in a well. The structure may be locked in a position determined by the inner dimensions of the well in which it is deployed. Practical uses for the structure may include production tubing or a host of other devices for affixing downhole with a final diameter as determined by the inner diameter of the well. Additionally, the structure may be configured for advancement to a targeted well location while in a collapsed state. Thus, upon deployment, subsequent structures may be advanced through the expanded/deployed structure. As such, affixed structures may be deployed downhole in both top-down and bottom-up fashions without concern over a prior deployed structure obstructing subsequent structure deployment downhole thereof.
