Transesterification of Non-Edible Vegetable Oil for Lubricant Applications in Water-Based Mud: A Review

摘要

The deterioration of the environment as a result of the disposal of oil-based mud used in the oil industry in offshore and onshore environment is alarming and preventive measures must be taken to protect it. Vegetable oil as biolubricant in water-base mud has proved to have potentials in formulating drilling mud for oil and gas exploration due to their inherent properties. Nevertheless, the direct usage of this plant oil is limited in application due to their high viscosity, unstable hydrolytic and oxidative effect. These parameters can be improved upon through transesterification process. This paper hereby review the derivable benefits of chemically modifying vegetable oil inorder to improve their physicochemical properties through transesterification reaction process, and the effect it will have when applied to drilling mud.
