摘要
The study of biopolymers is increasing considerably in the oil industry because they possess desirable properties such as environmental friendliness. Xanthan gum and scleroglucan are biopolymers used to reduce mud toxicity. These biopolymers are exopolysaccharides added to aid in control of fluid loss to the formation and to increase the viscosity of the drilling mud. In this article, we suggest evaluating the properties of biopolymers used in drilling mud. We constituted a fluid model compliant with the American Petroleum Institute's standards, where the composition differs by the nature of biopolymer. Biopolymer properties were investigated by using two main analytical methods: X-ray diffraction (XRD) and rheology. The substances used in this study are considered to cause little or no risk to the environment. This article describes the characterization of these polymers and the effect of additives such as clay and weighting material on drilling muds.
