| titleOfInvention | Water swellable clay composition and method to maintain stability in salt contaminated water |
| abstract | Abstract of the Disclosure Disclosed is a composition including a water swellable clay, and particularly a montmorillonite clay, such as bentonite; xanthan gum; and one or more additional water-soluble gums, for example, guar, dextran, acacia or locust bean. The xanthan gum to-gether with one or more additional water-soluble gums prevents montmorillonite clay composition from sub-stantial coagulation or flocculation upon contact with salt contaminated water even in high concentra-tions of, for example, 15-40% by weight salt. It has been found that xanthan gum in an amount of 0.1-20% based on the weight of the water-swellable clay, i.e. bentonite, in the composition together with one other water soluble gum, for example guar gum, dextran gum, acacia gum and/or locust bean gum in an amount of 1.0-10% based on the weight of bentonite in the compo-sition will provide a clay composition capable of excellent stability without component separation in salt contaminated water. The composition is par-ticularly useful as an additive to compositions used as stable drilling fluids in rotary drilling, and as lagoon and landfill sealants. |
