20130244912 | Delivery of Particulate Material Below Ground - A wellbore fluid is an aqueous carrier liquid with first and second hydrophobic particulate materials suspended therein. The first hydrophobic particles have a higher specific gravity than the second hydrophobic particles and the fluid also comprises a gas to wet the surface of the particles and bind them together as agglomerates. The fluid may be a fracturing fluid or gravel packing fluid and the first particulate material may be proppant or gravel. The lighter second particulate material and the gas both reduce the density of the agglomerates which form so that they settle more slowly from the fluid, or are buoyant and do not settle. This facilitates transport and placement in a hydraulic fracture or gravel pack. One application of this is when fracturing a gas-shale with slickwater. The benefit of reduced settling is better placement of proppant so that a greater amount of the fracture is propped open. | 09-19-2013 |
20150114648 | PARYLENE COATED CHEMICAL ENTITIES FOR DOWNHOLE TREATMENT APPLICATIONS - Fluids including a parylene-coated chemical entity and methods of treating a subterranean formation with such fluids are disclosed.

20150152321 | HETEROGENEOUS PROPPANT PLACEMENT - A method for forming proppant aggregates, for example downhole in an injection well, includes injecting a slurry including a thermo-responsive polymer with a low critical solution temperature and a proppant downhole, and heating the slurry above the low critical solution temperature of the polymer. The heating of the slurry above the low critical solution temperature of the polymer aggregates the proppant. A composition of the slurry includes a carrier fluid including a thermo-responsive polymer, a proppant, and optional additives. | 06-04-2015 |
20150175880 | METHOD OF VISCOSITY REDUCTION IN THE PRESENCE OF FULLY COORDINATED COMPOUNDS - Methods for reducing a viscosity of a viscosified fluid include reacting, such as by depolymerizing and/or decomposing, a polymeric material of the viscosified fluid with a breaking agent including a fully coordinated transition metal compound, such as a strongly complexed fully-coordinated transition metal compound. The methods of treating the subterranean are provided that include reacting, such as by depolymerizing and/or decomposing, a polymeric material of a viscosified treatment fluid with a fully coordinated transition metal compound, such as a strongly complexed fully-coordinated transition metal compound, to facilitate breaking of the viscosified treatment fluid after the fracturing or treatment is finished. | 06-25-2015 |
20150275644 | WELL TREATMENT - A method and system for increasing fracture conductivity. A slurry, of a solid particulate freely dispersed in fluid spaces around macrostructures suspended in a carrier fluid, is injected into a fracture, the solid particulate is aggregated in the fracture to form clusters, and the pressure reduced to prop the fracture open on the clusters and form interconnected, hydraulically conductive channels between the clusters. The system comprises a subterranean formation, a treatment slurry stage disposed in a wellbore penetrating the formation, and a pump system to inject the treatment fluid stage into a fracture. | 10-01-2015 |
