Cesium Formate: Results and Analysis of Drilling with a …
The cesium formate fluid was easy to handle and was relatively immune to contaminants. The cesium formate fluid produced more discrete shale cuttings. The formulations used exhibited high so-called "spurt loss", yet API fluid loss was low. Even so, the filter cake was of negligible thickness. No bit balling was observed for the cesium …

About cesium formate. Cesium formate (CsCOOH) is an alkali salt and member of the formate family with potassium formate and sodium formate. At 2.30 g/cm3 (19.2 lb/gal), it has the highest density of all formate brines. This clear brine is monovalent, with low viscosity and crystallisation temperature, and an adjustable alkaline pH.
