This invention relates to methods for preparing slurries that include depolymerized polysaccharides and depolymerized and derivatized polysaccharides that may be useful in subterranean well operations including fracturing, gravel packing, and frac-packing. One embodiment of the present invention provides a method for making a slurry, comprising combining a polysaccharide with an organic solvent to form a slurry; and, depolymerizing the polysaccharide in the slurry. Another embodiment of the present invention provides a method of treating subterranean formation with slurry comprising the steps of creating a slurry using a method comprising the steps of combining a polysaccharide with an organic solvent to form a slurry; and, depolymerizing the polysaccharide in the slurry; and, placing that slurry into a subterranean formation.

Systems and methods for treating aqueous fluids and their associated methods of use are disclosed. In one embodiment, a method comprises providing an untreated aqueous fluid with a first concentration of a contaminant. The method further comprises chemically treating the aqueous fluid to precipitate at least a portion of the contaminant. The method further comprises mechanically treating the aqueous fluid to remove at least some of the precipitated contaminant from the aqueous fluid, and to produce a treated water with a second concentration of the contaminant, wherein mechanically treating the aqueous fluid comprises flowing the aqueous fluid through a centrifuge. The method further comprises placing the treated water in a first well bore of the well treatment operation.

An electrostatic spray disinfecting system is integrated into a mobile environment to enable the mobile environment to be automatically subjected to an electrostatic spraying operation when the mobile environment is moving or stationary without the need for a human operator to participate in the spraying operation. An electrostatic sprayer of the system is mechanically coupled to a structure of the mobile environment in a preselected position relative to an internal compartment of the mobile environment. A reservoir of disinfecting material and is fluidly coupled to the electrostatic sprayer for delivering a flow of the disinfecting material to the sprayer. When an electrical switching circuit is placed in an On state, electrical power is delivered to the electrostatic sprayer to electrostatically charge the particles of the disinfecting material delivered to the electrostatic sprayer and to cause the electrostatically-charged particles to be sprayed from the electrostatic spray nozzle into the internal compartment.

The present invention provides liquid gelling agent concentrates and methods of treating wells therewith. A liquid gelling agent concentrate of this invention comprises an environmentally safe hydrocarbon carrier liquid, an organophillic clay suspending agent, a surfactant for dispersing the organophillic clay suspending agent in the carrier liquid and a particulate aqueous fluid gelling agent suspended in the carrier liquid.
摘要:
A folding stroller having a structural frame formed of a plurality of rigid support members. The stroller is provided with a skirt formed of a flexible material. The skirt can be disposed around at least a portion of an outer perimeter of the stroller to create a visual impression of something other than an ordinary stroller. For example, the skirt can create a visual impression of a vehicle such as an automobile, truck, airplane, spacecraft, an animal or a character. The skirt can be formed of fabric, plastic sheeting or film, or a mesh. A suspension frame is provided for suspending the skirt along a least a portion of an upper edge thereof. The suspension frame can at least partially define a profile of the vehicle, animal or character. The suspension frame folds with the structural frame of the stroller for ease of storage.

Illuminated display case for collectibles that can simulate the look and feel of a collectible's theme. The display case can be modular in design, such that one case can serve as the basis for the joining of additional case modules to form a larger illuminated display. Through the use of a specialized alignment structure, display cases can be lined up one next to the other to form a continuous track around a room.
