About Sirius-ES
Sirius-ES is a specialist company for demanding drilling projects in the oil, gas and geothermal sectors. The focus is on drilling fluids: the service portfolio includes planning and design of drilling fluids, technical monitoring of fluid parameters at the drilling site, cleaning of the drilling fluid using solids control equipment, management of proper drilling mud disposal, and logistics and project management with 24/7 support. In addition, the company offers its own developed fluid additives and liquid formulations for water- and oil-based systems (WBM/OBM) for deep drilling and horizontal drilling (HDD). In Celle, the company operates the Technical Service Laboratory (TSL) with full laboratory analytics including HTHP rheology, particle size analysis, X-ray diffraction (XRD) and aging tests; field laboratories in accordance with DIN EN ISO 10414-1:2008 are available at the drilling sites. Founded in 2010, the company with more than 60 employees and over 250 projects is ready for deployment throughout Europe with locations in Wels (AT), Celle and Spremberg (DE) as well as a subsidiary in Bucharest (RO).
