摘要： Disclosed is a hydrocarbon-based concentrate composition for crosslinking polysaccharide polymers in an aqueous-based fluid, such as a fracturing fluid, wherein the hydrocarbon-based composition has no or substantially no detectable levels of benzene, toluene, ethyl- benzene, and/or m-, 0-, or p-xylenes (BTEX). Preferred polysaccharide polymers are galactomannan gums or derivatives thereof. The con¬ centrate comprises an oleaginous solution, such as a hydrocarbon dis¬ tillate, a crosslinking agent for crosslinking the polysaccharide poly¬ mer, preferably a sparingly soluble alkali metal or alkali metal alka¬ line earth metal borate, and a stabilizing/suspension agent, preferably a clay mineral selected from the group consisting of smectite clays. The concentrate may, optionally, contain a deflocculant and/or an an- ti-syneresis additive.

摘要： The invention provides (1) a method of increasing the thermal stability of an oleaginous liquid containing a high surface area silica viscosifier therein by adding a water soluble biopolymer thereto; and (2) a drilling, completion, workover, or well servicing fluid comprising an oleaginous liquid, a water soluble biopolymer, and a high surface area silica viscosifier. The method and fluid may optionally contain a low molecular weight polar additive preferably having a molecular weight less than about 400 and containing one or more polar groups per molecule selected from the group consisting of hydroxyl, amino, and mixtures to thereof.

摘要： The invention provides: (1) a process to enhance the removal of solids such as clays, clay-like solids, and shale solids-drill solids-from the surface of a borehole, the solids being deposited from well drilling, completion, or workover fluids during well servicing operations; and (2) a process to enhance the removal of such solids from screens or other sand control devices present in a borehole. The process comprises contacting the solids with an acidic soak solution containing a polyglycol or mono ether derivative thereof and thereafter contacting the surface of the borehole with a wash solution to remove the solids from the borehole.

摘要： There is disclosed a method of delaying the setting time of aqueous lost circulation control pills. The aqueous lost circulation control pills contain a crosslinkable polymer viscosifier, one or more water retention additives, a crosslinking agent, a pH control agent, and a crosslink time regulator. The method comprises utilizing as the crosslink time regulator encapsulated sodium chloride. The preferred crosslinkable polymer is xanthan gum. The preferred water retention additives are pregelatinized starch and a polyanionic cellulose derivative. The preferred crosslinking agent is a hydrated borate. The preferred pH control agent is magnesium oxide. Preferably the sodium chloride is encapsulated with a urethane coating.
