Abstract: This paper presents a novel water-based mud (WBM) that utilised certain environmentally friendly bioenhancers additives to improve its overall effectiveness of mud properties (pH, mud weight, corrosion tendencies, and viscosity) in drill fluid system. The primary base bio-additives in the WBM used in our research are banana peels ash (BPA), orange peel ash (OPA), and a mixture of OPA/BPA. Thus, different formulations of the drilling fluid systems were treated with bio-additives (OPA, BPA and BPA/OPA) and caustic soda. The test samples (samples A to E) were formulated at different concentrations of BPA, OPA, BPA/OPA mixture, and caustic soda. Sample A was taken as the control sample. The investigations were carried out in line with the American Petroleum Institute (API) standards to check for improvement in pH and other fluid properties' specifications such as laxity, yield, suspensions, and viscosity on the initial empirical pilot experimentation.

Keywords: corrosion; banana peels ash; BPA; orange peel ash; OPA; mud enhancers; viscosity; drilling; pH control.
