About Us

Founded in 2014, Tachyus is a leader in operational optimization for the oil and gas industry. Aqueon, our waterflood modeling and optimization platform powered by our proprietary engine Data Physics, has increased production and reduced costs and GHG emissions for operators worldwide. We also recently extended Aqueon for CO2 EOR optimization, which major US operators already use.

In early 2022, Tachyus entered the ESG space with Aurion, a fully integrated software platform that helps GHG-intensive industries like oil and gas estimate, forecast, optimize and report GHG emissions and intensity. Since then, we have rapidly established ourselves as a leader, with over 20 clients in the US, the Middle East, and Latin America.
