Abstract: A tubular segment that has openings that are initially closed so that pressure can be conducted through the segment has the ability to open the segments by making a degradable material unblock the openings to facilitate another completion operation or production. Some applications include a slotted liner with a screen where an intermediate layer of a controlled electrolytic material initially allows the structure to conduct pressure and then after degradation allows access through the screen and the slotted liner for production. Other variations can be simply using slotted liner where the slots are closed for running it to allow circulation and then opened for production or other completion steps. The transformation can take place over time using available well fluids or it can take place with induced well conditions at the location that are initiated from the surface or locally at the location.

Abstract: Wellbore devices for use in filtration, wellbore isolation, production control, lifecycle management and wellbore construction may include at least a first and a second shape-memory material each having an altered geometric position and each an original geometric position. Each shape-memory material may be held in the altered geometric run-in position at a temperature below glass transition temperature (Tg), where the Tgs and/or the respective slope changes of the first and second shape-memory materials are different. Optionally the shape-memory materials may be crosslinked polymers where the crosslinked polymers have different crosslinking ratios from one another. Once the wellbore device is in place downhole and the first and second shape-memory materials are subjected to temperatures above their Tgs, the materials will deploy to recovered geometric positions at or near their original geometric positions to perform their filtration, isolation, control or other function.

Abstract: An apparatus and method for restricting fluid flow with a seat assembly. The seat is configured to go from a first position, in which it is adapted to engage a plug element, to a second position, in which the plug element passes through the seat. A second portion of the seat, and alternatively of a housing in which the seat is disposed, is formed of a disintegrable material. The second portion of the seat and housing comprising the disintegrable material are isolated from a fluid flow when engaged with the seat.

Abstract: A composite particle comprises a core, a shielding layer deposited on the core, and further comprises an interlayer region formed at an interface of the shielding layer and the core, the interlayer region having a reactivity less than that of the core, and the shielding layer having a reactivity less than that of the interlayer region, a metallic layer not identical to the shielding layer and deposited on the shielding layer, the metallic layer having a reactivity less than that of the core, and optionally, an adhesion metal layer deposited on the metallic layer, wherein the composite particles have a corrosion rate of about 0.1 to about 450 mg/cm2/hour using an aqueous 3 wt % KCl solution at 200° F. An article comprises composite particles, wherein has a corrosion rates of about 0.1 to about 450 mg/cm2/hour using an aqueous 3 wt % KCl solution at 200° F.

Abstract: A seal comprises: a first portion including a crosslinked product of: a first crosslinked polymer; and a second crosslinked polymer; and a second portion including a polymer which is different than a constituent polymer in the first portion, wherein the seal has a gradient in glass transition temperature. A method for sealing comprises: disposing the seal of claim 1 in an opening; heating the seal to a temperature greater than a minimum value of the glass transition temperature of the gradient; and applying pressure to an elastic portion of the seal for sealing the opening.

Abstract: An article includes a crosslinked product of: a first crosslinked polymer and a second crosslinked polymer, wherein the article has a gradient in glass transition temperature. A process for making the article includes combining a first crosslinked polymer and a second crosslinked polymer to form a composition; compressing the composition; heating the composition; and crosslinking the composition to form the article, the article having a gradient in glass transition temperature. An article can be a seal that includes a first portion including a crosslinked product of: a first crosslinked polymer and a second crosslinked polymer; and a second portion including a polymer which is different than a constituent polymer in the first portion, wherein the seal has a gradient in glass transition temperature.

Abstract: Wellbore devices for use in filtration, wellbore isolation, production control, lifecycle management and wellbore construction may include at least a first and a second shape-memory material each having a an altered geometric position and each an original geometric position. Each shape-memory material may include a polyurethane material held in the altered geometric run-in position at a temperature below glass transition temperature (Tg), where the Tgs and/or the respective slope changes of the first and second polyurethane materials are different. Once the wellbore device is in place downhole and the first and second shape-memory materials are subjected to temperatures above their Tgs, the materials will deploy and expand to recovered geometric positions at or near their original geometric positions to perform their filtration, isolation, control or other function. These deployments or expansions may occur at different times or rates.
