The performance of waste frying palm oil biodiesel as ester-based drilling fluid

Ester based mud (EBM) derived from vegetable oil has been known as one of the alternative for conventional oil-based mud due to its environmental friendly properties. However, the cost for ester, or biodiesel, derived from virgin oil are relatively high compared to conventional oil-based mud. The us...

However, the NBR components lost more than 80% of its initial strength after exposure at 125oC due to incompatibility of NBR components at such high temperature. As for toxicity study, the Cyprinus Caprio (carp fish) has been used as test organism. The LC50 of WFPOB and the blending mud obtained in this study is 56,000 ppm and 32,000 ppm which lies under Practically Non-Toxic category in toxicity classification. The result shows that the WFPOB mud can be used as base oil in drilling mud formulation with certain limitation.
