DRILLING FLUID SYSTEMS COMPRISING LATEX PARTICLES

摘要

Latex additives, methods for treating latex additives, drilling fluid systems, and lost circulation pills comprising the latex additives, the latex additive comprising latex particles having a particle size distribution before aging comprising an average particle diameter of about 1 micron or less; and a quantity of one or more water soluble oxygenated organic molecules comprising two or more oxygen atoms effective to maintain substantially the same particle size distribution before and after freezing the latex additive.
