Abstract
This invention relates to an aqueous well servicing fluid comprising in solution a cesium salt of a carboxylic acid characterised in that the carboxylic acid has: a) at least one carboxyl group and b) at least one other carboxyl and/or hydroxy group. Typical examples are cesium lactate, citrate and oxalate. Use of these cesium salts enables the production of dense brines usable as well servicing fluids.
