The objective of this research study is to develop a high-performance ester-based drilling fluid using Calophyllum Inophyllum oil as base fluid. The crude Calophyllum Inophyllum oil is extracted and synthesized to produce biodiesel by two-step esterification and transesterification process at optimum conditions. The produced biodiesel is used as a base oil for the formulation of ester-based drilling fluid. A 12 ppg and 14 ppg drilling fluid are formulated with an oil-water ratio of 70:30 and 80:20. The rheological and filtration tests are performed at ambient conditions along with electrical stability and lubricity. The performance of the ester-based drilling fluid is evaluated by comparing the rheological and filtration properties with commercially available oil-based drilling fluids. The test results exhibit that the newly developed ester-based drilling fluid has improved rheological and filtration properties with better emulsion stability. It is anticipated from the results that the Calophyllum Inophyllum ester-based drilling fluid has the potential to overcome the technical and environmental challenges.
