Abstract: The invention provides a method for producing guar gum, the method comprising the steps of: (a) sizing husk from guar seed into larger pieces and smaller pieces, (b) washing the larger pieces, (c) soaking the larger pieces, and (d) flaking the larger pieces to obtain guar gum. The invention also provides a method for processing undehusked guar splits, the method comprising the steps of: (a) dehusking undehusked guar splits to obtain dehusked guar splits and husk, and (b) sizing the husk into larger pieces and smaller pieces.

Abstract: An apparatus for testing a rheological property of a fluid with a particulate includes: (a) a receptacle having a cylindrical side wall enclosed by a bottom wall defining a cavity for receiving a fluid to be tested; (b) an axial support adapted to be positioned in the cavity of the receptacle, whereby relative rotational motion can be imparted to the receptacle and the axial support; (c) at least one inward projection extending inward from an inside surface of the receptacle; (d) at least one outward projection extending outward from the axial support; and (e) at least one projection for directing fluid flow that has at least one major surface angled or curved upward. A method of testing a Theological property of a fluid with a particulate includes: (a) placing a sample of the fluid and the particulate in the apparatus; (b) imparting relative rotational motion to the receptacle and the axial support; and (c) measuring the torque between the receptacle and the axial support.

Abstract: Methods of servicing a wellbore include generating gas in a plugging composition in situ within a permeable zone in the wellbore, thereby improving the ability of the plugging composition to seal the permeable zone. The gas may be generated via a chemical reaction by, for example, introducing first and second reactants to the plugging composition that can react at ambient temperatures in the wellbore. In an embodiment, the first and second reactants are concurrently pumped into the wellbore via separate flow paths within two concentric conduits to the permeable zone where they are allowed to contact each other in the presence of the plugging composition. In another embodiment, the first reactant, the second reactant, and a retarder for slowing the reaction between the two reactants are concurrently pumped to the permeable zone. In yet another embodiment, one of the reactants is encapsulated to delay a reaction between the two reactants.

Abstract: The invention relates to methods for improving the suspension of solids in liquids; more particularly, to reducing the potential stresses caused by increased particle loading in a fluid. An example of a method is a method of enhancing the flow of particles. Another example of a method is a method of fracturing a subterranean formation. Another example of a method is a method of gravel packing a portion of a subterranean formation. Another example of a method is a method of enhancing the flow of drill cuttings. An example of a composition is a treatment fluid comprising a liquid component and a solid component.
