Formate Technical Manual, Part A: Chemical and Physical Properties
Section A7: Thermophysical Properties
|
|
Thermophysical properties, such as thermal conductivity and specific heat capacity, are important for drilling fluids as they influence the bottom-hole circulating temperatures. Water-based fluids, including formates, generally have higher thermal conductivity and specific heat capacity than oil-based fluids, which is beneficial. This section of the manual presents measured thermophysical data for a serious of realistic sodium, potassium and cesium formate brine blends as a function of temperature.
