Contribution to
innovative projects
Participation in international research projects
We are committed to advancing sustainable technologies through international and national research collaborations. Our focus is on the development of environmentally friendly drilling fluids, innovative solids control devices, and new stabilizers that replace harmful biocides. In addition, Sirius-ES is driving forward concepts such as the upcycling of drill cuttings, transforming waste into a valuable resource for the construction materials industry.
NEFI - CASCADE
Part of the "New Energy for Industry" initiative in Upper Austria, the project combines the cascade use of heat – from high-temperature industrial supply to low-temperature heating and cooling – with Sirius-ES' contributions to the upcycling of drilling cuttings and the development of environmentally friendly drilling muds.
OBF - Optimization & field qualification of a fluid-driven drill hammer
Research project with the TU Clausthal and partners from the drilling industry for the development, testing and qualification of fluid-operated hammer drills.
Sirius STAB 10
A natural, hop-based stabilizer developed in collaboration with leading industry partners and the University of Natural Resources and Life Sciences, Vienna, it offers an environmentally friendly, FDA-approved alternative to conventional biocides and is currently undergoing extensive laboratory and field trials.
