Formate drilling fluid is a new type of clean brine drilling fluid system which has been developed from inorganic salt brine drilling fluid system. Currently there are mainly three kinds of format: sodium format, potassium format and cesium format. The laboratory research was carried out to determine the thermal stability of drilling fluid. It was formulated using sodium and potassium format salts, potassium chloride. Formate base mud is solid free system. So, mud cake is thin and resilient, it is conductive to improve cementing quality greatly. Formate base fluids because of their low percent of solid settling. Moreover, the low amount of plastic viscosity these muds help to better hydraulic in the well and better hole cleaning. Hence, drilling penetration rate as an extremely parameter in economic costs are decreased. Environmental pollution of formate salts is dramatically less than recent salts like potassium chloride and sodium chloride. It can be appropriate replacement for these environmental polluted salts.
