&#34;Long-term partnerships with global energy leaders are built on consistent performance, technical expertise, and the ability to solve demanding challenges,&#34; said Vijay Manthripragada, Chief Executive Officer of Onterris. &#34;The continued work reflects our client&#39;s confidence in Onterris to deliver practical, science-based solutions that support environmental stewardship, regulatory compliance, and responsible energy development.&#34;

</p><p xmlns="http://www.w3.org/1999/xhtml">
Today, Onterris supports the client across upstream, midstream, and downstream operations, including refining and petrochemicals, as well as emerging energy.
