Cesium formate fluids from Sinomine Specialty Fluids have delivered highly productive wells for more than 20 years without any well control incidents at temperatures as high as 235°C (455°F) and pressures up to 1,126 bar (16,331 psi). From the North Sea to the South China Sea and the Caspian to Hungary, our fluids have overcome some of the toughest challenges the oil and gas industry faces.
BP, ConocoPhillips, Equinor, Petrobras, Saudi Aramco, Shell, Total and many other operators have relied on our fluids in some of their most challenging well-construction operations. They’ve seen that our ‘performance through simplicity’ philosophy works. They understand that we do not need to overcomplicate our formulations with many – or any – additives. That the naturally stable high density of cesium formate brine, coupled with its remarkable monovalent, alkaline and low water activity properties, deliver exceptional multi-applicational versatility. Moreover, they’ve seen the additional savings in time and cost through simplifying operations further by drilling and completing in the same cesium formate fluid.
Cesium formate fluids are available in densities from 1.57 g/cm3 to 2.30 g/cm3 (13.1 lb/gal to 19.2 lb/gal). Talk to us about how cesium formate fluids can make the difference to your next well construction.
Maximise reservoir productivity with our low-solids, non-damaging drill-in and completion fluids made from cesium formate brine. They’re ideal for optimising and simplifying challenging reservoir drilling and completion operations. The high versatility of cesium formate drill-in and completion fluids delivers field-proven solutions for:
The unique properties of cesium formate base brine give rise to a whole range of valuable benefits, such as higher rate of penetration (ROP), low equivalent circulating density (ECD), stable shales, no stuck pipe and excellent well control. Those operators that use it both for drill-in and completion operations see the largest efficiency gains, including elimination of fluid displacement and cleanup time. For more information, please see our video, Drill-in and Completion brochure and Save Weeks Drilling and Completing brochure.
Cesium formate forms powerful drilling fluids to optimise drilling operations safely and effectively. The special properties inherent in cesium formate fluids deliver major benefits, such as enhanced well control, faster ROP, lower ECD, minimal non-productive time, better hydraulics and lower torque and drag values for extended-reach and high-angle drilling.

Cesium formate brine delivers a safe, trouble-free hydrostatic barrier for clean completions, workovers, suspensions and interventions. They’ve proven their worth for operators across the globe as effective:
These remarkable fluids with their unique mix of properties provide key benefits, including faster, cleaner and safer operations, reduced operational risk and lower environmental impact. For more information, please download our Clear Brine Fluids brochure.
In 2015, well engineering consultancy Ridge AS completed a study of 89 North Sea wells. Ridge concluded that formate fluids outperform other fluids to deliver significant rig-time savings for both openhole and cased and perforated completions by enabling more time-efficient solutions.
