Effective Modified Xanthan Gum Fluid Loss Agent for High
Xanthan gum XG was widely used as an oilfield chemical treatment agent because of its environmental protection and diverse functions. With the increased drilling depth andplexity, thegs such as poor solubility and low resistance to temperature were gradually exposed. In this study, a modified XG derivative XG g AAA was synthesized by

Executive Summary Asbestiform Fibers: Nonoccupational
Attapulgite palygorskite is the only natural asbestiform material used in the United States in amounts greater than those of asbestos. Of the more than 700,000 metric tons used annually, most appears to be classifiable as anbestiform. Most attapulgite fibers are less than 5 Am long and have diameters of approximately 0.03 pm.
