Formate based fluids are environmentally friendly and biodegradable drilling fluids that are compatible and solid free, contributing to eliminate formation damage. In this regard, they find their application in drilling fluids, as well as in completion fluids. In this work, three potassium formate based fluids of different concentrations such as 40, 50, 60 % w/w and water-based fluid (WBF) are prepared with help of additives namely, calcium carbonate, xanthan gum and ethylene glycol. The consistent performance of a drilling, completion or workover fluid is very much necessary for successful and economical drilling, completion or workover operation. Hence the synthesized fluid samples with various concentrations of potassium based fluids are analyzed for their rheological behavior at various temperatures and a function of time.
