Effectiveness of Ultra Sonication on Graphene Characterization in Water Based Drilling Fluid (WBDF) at Elevated Temperature

Akila Mathivanan M*

The main aim of this project is to study the effectiveness of sonication on the graphene characterization in water based mud at elevated temperature. In this project, the graphene sheets will be sonicated using a probe sonicator and added into water based mud. The most optimized sonication time and power that is efficient in giving the best properties of graphene are studied. The sonication time and power must also not damage the graphene sheet properties. In this project study, the graphene sheets are then characterized based on various ways. Sonication of graphene with mud will affect its particle size and number of graphene sheet which will result in change of the drilling fluid properties such as plastic viscosity, yield point and gel strength before and after hot rolled. The properties are studied using equipment such as viscometer, roller oven and mud balance. As for the properties of graphene, it will be separated from the liquid using Low Pressure, Low Temperature (LPLT) filter press equipment and left to dry. It is then examined using FESEM and XRD to give the estimation of spacing and graphene sheet quality.
