Abstract: The present disclosure relates to multi-layer composite articles including at least two nonwoven web layers. Each or the layers may be a spunbonded web, and each may include biodegradable materials. The multi-layered composites of the present disclosure are particularly well suited for air filtration, as they can combine a high dust holding capacity with sufficient strength, dimensional stability, and a relatively low pressure drop.

Abstract: Methods of contacting a subterranean formation are described which provide improved control or reduction of particulate migration, transport or flowback in wellbores and reservoirs, and which may do so without sacrificing substantial hydraulic conductivity. One method comprises injecting into a well-bore intersecting the subterranean formation a fluid composition comprising a first component and a second component dispersed in a carrier fluid, at least a portion of the first component or second component being provided as at least one multicomponent article having an aspect ratio greater than 1:1.1; forming a network comprising the first component; and binding the network with the second component.

Abstract: Fluid compositions and methods of making and using same are described, one composition comprising a well treatment fluid and an additive combined with the well treatment fluid, wherein the additive is selected from solids, liquids and combinations thereof, the additive having a surface shape, at least one property of the surface shape enabling it to change under influence of a controllable parameter after the composition is deployed into a hydraulic fracture or gravel pack. In methods of the disclosure, the additive exists initially in a first state, and then is changed to a second state. The first state may increase proppant flowback efficiency, while the second state may increase hydraulic conductivity. In certain embodiments, the additive may change back to its first state.

Abstract: Light-collimating films as well as other microstructured film articles are described that comprise a (e.g. UV) cured light transmissive film comprising the reaction product of a polymerizable resin composition. Polymerizable resin compositions are also described that comprise aliphatic urethane (meth)acrylate oligomer(s), bisphenol-A ethoxylated diacrylate(s), and a crosslinker having at least three (meth)acrylate groups.
