Abstract

* Corresponding author Abstract: C10 esters obtained from octanoic acid and acetic acid were evaluated for their suitability as base fluids in oil and gas wells drilling mud formulation. Comparison of the physicochemical parameters of the esters with that reported in literature revealed an agreement between the two sets of values. Two mud formulations were designed from each of the esters and their rheology profile between 80 o F and 200 o F compared with that of a commercially available synthetic base fluid. The result of the rheological tests performed on all the drilling muds formulated indicated that with appropriate additives, the mud formulation using the two synthetic esters could perform as good as the reference fluid.
