Drilling muds are fluids used to keep up well control and transport drill cuttings from the boreholes to the surface. They are complex formulations of a range of chemicals designed to have specific properties under very specific drilling conditions. Most of these chemicals are toxic and pose an excessive threat to mankind as well as the environment. However, drilling muds must be formulated with stabilized properties to achieve optimum drilling operations at the lowest cost possible and minimum environmental impact. In connection, the increase in environmental awareness has made petroleum industries are demanding for high performance and environmentally friendly mud systems, therefore, the drilling mud service companies started to re-evaluate some of the chemicals and materials used as additives for mud systems, different naturally occurring materials with similar properties as these chemicals are evaluated for commercial applications. In the current presentation, the environmental issues and concerns for some of the chemicals used as additives for conventional drilling fluid system will be highlighted. Some green materials may be considered as possible substitutes for the chemicals used in formulation water and oilbased drilling fluid systems will be reviewed including agro waste materials and nano additives synthesized by biosynthesis routes in situ. The role of the green additives on rheological and thixotropic characteristics is demonstrated. Utilization of mathematical and statistical techniques for modeling and optimization the effect of the content and properties of the green additives on drilling mud performance will be discussed and overviewed.
