20080287563 | WEATHER RESISTANT, INK JETTABLE, RADIATION CURABLE, FLUID COMPOSITIONS PARTICULARLY SUITABLE FOR OUTDOOR APPLICATIONS - Low viscosity, radiation curable fluid formulations that can be used advantageously as radiation curable, inks. The formulations are easily prepared for use in ink jet systems. The viscosity of the compositions is low enough so that conventional solvent is not required in order to satisfy the requisite low ink jet viscosity specifications. After curing, the compositions form durable, weatherable, abrasion resistant, printed images on a wide variety of porous and nonporous substrates. The formulations are very suitable for outdoor printing applications, especially for printing outdoor graphics onto a variety of surfaces, including vinyl or other polymer films commonly used for signage, retroreflective signage or other retroreflective items. | 11-20-2008 |
20100263865 | PROPPANTS AND USES THEREOF - Compositions comprising a proppant core having an outer surface and polymeric microspheres attached to at least a portion of the outer surface are described. The compositions are useful, for example, to increase the productivity of a hydrocarbon oil or gas bearing well. | 10-21-2010 |
20100263870 | METHODS OF CONTACTING AND/OR TREATING A SUBTERRANEAN FORMATION - 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. | 10-21-2010 |
20100272994 | MULTI-COMPONENT FIBERS - Multi-component fibers comprising at least one polymer having a softening temperature up to 150° C., and another polymer having a melting point of at least 130° C. The fibers are non-fusing up to at least 110° C. The fibers are useful, for example, for flowback control in wellbores and reservoirs. | 10-28-2010 |
20100282468 | FRACTURING FLUID COMPOSITIONS COMPRISING SOLID EPOXY PARTICLES AND METHODS OF USE - Fluid compositions and methods of making and using same are described, the fluid compositions comprising at least one solid epoxy particle, at least one epoxy resin curing agent, and at least one type of proppant particles. The methods comprise deploying a fluid composition into a wellbore extending to a subterranean geological formation using pressure sufficient to form a fracture in the subterranean geological formation, and immobilizing at least a portion of the solid epoxy particles and proppant particles in the fracture. Embodiments of the fluid compositions are useful for increasing hydrocarbon production from subterranean geologic formations, and/or controlling solids migration in such formations. | 11-11-2010 |
20100288495 | METHODS OF TREATING SUBTERRANEAN WELLS USING CHANGEABLE ADDITIVES - 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. | 11-18-2010 |
20100288500 | FIBER AGGREGATE - Fiber aggregate comprising organic polymeric fibers, wherein the organic polymeric fibers have an average length in a range from 2 to 20 millimeters, an average diameter up to 100 micrometer, and comprise at least 75 percent by solid volume of the fiber aggregate, wherein the fiber aggregate has an unrestrained bulk density of at least 0.05 g/cm | 11-18-2010 |
