Evaluation of Non-Ionic and Anionic Surfactants as Additives for Water-Based Mud
Putri Yunita, Sonny Irawan, Dina Kania
Abstract
Water-based mud (WBM) is known as the cheapest drilling fluid that possess other advantages such as environmentally friendly and non-hazardous. Compared to oil-based mud (OBM) or synthetic-based mud (SBM), WBM is more largely used in oil and gas exploration. In this study, new no-ionic surfactant and anionic surfactant were evaluated as an additive in WBM. Rheological properties in WBMs containing surfactant as additive were investigated which included the plastic viscosity, the yield point, the gel strength and filtration properties. The result of the studied non-ionic and anionic surfactants showed improvement in the rheological properties and thermal stability of the mud when used as additive for WBM.
