Industry media spotlight our first shipment from Singapore Resid Upgrade Project (SURP)

In September 2025, we marked a major milestone with the first shipment of Group II base stocks from our upgraded Singapore refining complex. The Singapore Resid Upgrade Project (SURP) equipped the site with the technology needed to covert 'bottom-of the-barrel' streams into lower sulfur fuels and high-performance base stocks. This investment strengthened our global manufacturing network and has helped enhance supply reliability across Asia-Pacific and beyond.

Among the products shipped was EHC 340 MAX™, our new Group II extra-heavy neutral base stock. It offers the viscosity profile of a traditional bright stock—along with the quality benefits of Group II, including lower sulfur and improved oxidation stability.

Several leading publications covered the milestone: Hydrocarbon Processing reported the expansion’s 20,000 barrels-per-day capacity increase, including EHC™ 50, EHC™ 120 and EHC 340 MAX™. Hydrocarbon Engineering noted that additive suppliers have released market-general formulations to support wide adoption of EHC 340 MAX™. Oil and Gas Journal detailed the proprietary process technology that made the creation of EHC 340 MAX™ possible.

These articles reinforce the significance of this launch and our commitment to delivering versatile, high-quality Group II solutions at scale.
