Abstract: A wire cross-sectional shape for a wire wrap screen provides a primary and secondary gap with a contained circumferential volume in between. The secondary gap extends screen life by taking the place of the primary gap if erosion opens the primary gap and lets the larger solids get past. The closed space between the primary and secondary gaps also has the effect of reducing velocity due to the enlarged volume before the secondary gap is reached while also creating turbulence between the gaps to slow the fluid velocity to protect the secondary gap. All or parts of the wire outer surface can optionally be coated to extend service life.

Abstract: A well with existing perforations is re-fractured by positioning isolators at locations offset from the existing perforations and perforating through those isolators. The isolators are part of a bottom hole assembly that can be delivered on coiled or rigid tubing. The initial fractures can be straddled by the isolators with no mandrel openings between them to effectively isolate the existing perforations as new perforations take place through the isolators. The elements of the isolators can have internal gaps to allow for axial shifting after perforation that is thermally induced. The gaps assure remaining alignment with the new perforations despite some axial shifting. The bottom hole assembly can alternatively have an anchor to resist thermally induced forces that can cause axial shifting.

Abstract: A fully disintegrating plug has a passage therethrough and a ball seat at an upper end. The seal material that comprises plastic nuggets, sand and a grease binder is initially disposed behind a protective sleeve. A wireline setting tool creates relative movement between a plunger and a mandrel body that has a ramp surface adjacent the outlet of the protective sleeve. The sleeve outlet is closed for running in but plunger movement pushes the seal material so as to displace the closure at the sleeve outlet with the seal material that is forced up the mandrel ramp surface and against the surrounding tubular. After an object is landed on the mandrel seat and the treating is concluded, the plug components are caused to disintegrate or otherwise fail for complete removal. Multiple plugs are contemplated for fracturing or other treating applications.

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: A fracturing operation is done in open hole without annular space isolation. The annular space is spanned by extendable members that are located behind isolation valves. The extendable members can comprise a biodegradable plug that allows extension of the extendable members by application of pressure. With the plug remained in place, additional pressure can be delivered until at least a portion of the degradable material is pushed onto the surface of the formation. At least a portion of the pushed degradable material provides a seal between the end of the extendable members and the surface of the formation to allow pressure to build until the formation frac gradient is exceeded and the formation is fraced.

Abstract: Actuation and control of the deployment of a polymeric memory-shape material on a wellbore device on a downhole tool may be accomplished by treating a compacted or compressed polymeric memory-shape material with an optional deployment fluid to lower its Tg and/or decrease its rigidity, thereby softening the polymeric shape-memory material at a given temperature and triggering its expansion or recovery at a lower temperature. Recovering the polymeric shape-memory material may occur by its being exposed to a particular temperature range. Alternatively, the deployment of the compacted or compressed polymeric memory-shape material may be prevented or inhibited by shielding the material with an environment of a fluid that does not substantially lower its Tg, decrease its rigidity or both, and then subsequently contacting the material with a deployment fluid. The deployment fluid may be removed during the method.
