What Sirius does

Sirius-ES Handels GmbH is a privately held Austrian specialty drilling-fluids company founded in December 2009 and headquartered in Wels, Austria, with operating subsidiaries in Celle and Spremberg, Germany, and Bucharest, Romania. The company designs, supplies, and services water-based and non-aqueous drilling fluid systems, weighting agents, viscosifiers, lubricants, clay inhibitors, fluid-loss controllers, lost circulation materials, and corrosion inhibitors — including a proprietary S-ES branded product line (e.g., S-ES Calcium Carbonate Fine, S-ES PAC LV, S-ES Bio XG, S-ES HYB HS, and the Sirius Stab XL hop-based biostabilizer co-developed with BOKU). Its equipment fleet consists of mobile compact solids-control units (two centrifuges, flocculation station, barite recovery in 20ft containers), shale shakers, storage tanks, eccentric screw pumps, three-phase transformers, and mobile field laboratories operating to DIN EN ISO 10414-1:2008. The Celle site houses a Technical Service Laboratory equipped with a Malvern Mastersizer 3000 Pro, PANalytical Aeris Compact XRD, HT Dynamic Swell Meter, and Ofite HTHP Rheometer Model 77 for R&D and quality assurance.

The company serves three primary verticals: oil and gas exploration and production, deep geothermal energy (heating, district heating, power generation), and HDD/horizontal directional drilling for trenchless infrastructure. Customers include enterprise E&P and energy majors such as RAG Rohoel-Aufsuchungs, OMV Austria Exploration & Production, ExxonMobil Production Germany, EWE AG, Bayerngas, Rhein Petroleum, Romgaz, NAFTA a.s., Daldrup & Söhne, and Vermilion Energy, alongside geothermal specialists such as GEOenergie Kirchweidach, Geothermische Kraftwerksgesellschaft Traunreut, Geothermie Holzkirchen, DEEEP, Saline Austria, and TOP-THERMAL.

Sirius-ES earns revenue through three streams: (1) one-time sales of proprietary and third-party drilling-fluid chemical products; (2) professional services including field engineering, mud logging, fluid monitoring, project management, and laboratory analyses; and (3) equipment rental and sale, plus bundled waste management and logistics services. Pricing is quote-based B2B, with no public price list and multi-year contracts typical. The company is privately held, founder/management-owned (Alexander Buchner as CEO, Mohamed Faris as CFO, Roland Faschingbauer as COO), with no disclosed outside investors. As of 2025/2026 it reports 60+ employees and 250+ projects completed or ongoing across 18 European countries, and holds SCCp (since 2011), EN ISO 9001, EN ISO 14001, and EcoVadis Bronze (2024) certifications alongside Bundesverband Geothermie membership.

Recent moves10 records

Expansion highlights6 records

Broad incumbents

• SLB (formerly Schlumberger): Global oilfield services major with the M-I SWACO drilling-fluids franchise, directional drilling, and integrated drilling services. Provides direct competition to Sirius-ES on deep-well fluid systems, especially as it expands into geothermal and energy-transition applications.
• Halliburton: Global oilfield services incumbent offering drilling fluids (Baroid), directional drilling, and integrated well construction. Operates in the same upstream drilling-fluids market as Sirius-ES but at vastly larger scale and across all major regions.
• Baker Hughes: Global oilfield services and energy technology company with drilling fluids, drilling services, and turbomachinery. Overlaps with Sirius-ES in drilling-fluid chemistry and well construction, with a far broader portfolio and global reach.

Direct peers

• CES Energy Solutions: Canadian drilling-fluids and production chemistry specialist with operations across North America. Directly comparable to Sirius-ES as a drilling-fluid chemistry business serving both oil & gas operators and drilling contractors, with bundled product + service model.
• Tetra Technologies: US oilfield services and chemistry company with a drilling and completion fluids segment. Comparable to Sirius-ES as a fluids-focused specialty oilfield services provider serving operators and drilling contractors, though with broader commodity exposure.
• Newpark Resources: US-based specialty fluids and integrated services provider focused exclusively on drilling fluids and related oilfield chemistry. Closely comparable to Sirius-ES as a chemistry-led, non-major specialty drilling-fluids supplier with global ambition but smaller scale than Halliburton/SLB.
• Wyo-Ben Inc. US bentonite producer supplying drilling fluids, HDD products, and specialty absorbents to oil & gas, HDD, water-well, and environmental markets. Closely comparable to Sirius-ES on the bentonite-based chemistry and HDD-fluid axes.
• CETCO / Mineral Technologies: CETCO (now within Mineral Technologies) supplies drilling fluids, bentonite-based products, and HDD grouts globally. Closely comparable to Sirius-ES in product portfolio (drilling fluids, HDD additives) and customer overlap (drilling contractors, geothermal, water-well).
• AMC Drilling Optimisation: Australian manufacturer of drilling fluids, grouts, and HDD bentonite products, including HDD-specific product lines. Highly comparable to Sirius-ES on the HDD / bentonite / specialty fluids axis and as a smaller specialty player.
• Imdex Limited: Australian-listed drilling fluids, downhole sensors, and mining-tech provider serving mineral exploration and drilling contractors. Comparable to Sirius-ES as a chemistry-led specialty supplier with HDD / drilling-fluid products and a regional operating model.
