Nowadays, the adverse effect of drilling operations on the ecological system pushed the oil industry specialists to achieve optimum drilling performances. Volume and toxicity of discharged materials evaluate surface discharge severity. The ubiquitous utilization of formate fluids has revolutionized the way petroleum industries have conquered the lower drilling inefficiencies. As an objective of this extensive study, the profound impact of different pollutants on the potassium/sodium formate fluids was investigated by experimental tests. The particular sample for mud pollution test was formate fluid with starch biopolymers. To do this, five samples of formate fluids were made, and each one of them was polluted by several contaminants such as cement, lime, acid, alkali and stucco. Consequently, the rheological properties and the pH changes, as well as their effects on the formate fluids were evaluated.
