Lubes’n’Greases spotlights Singapore Resid Upgrade Project (SURP)

In Lubes’n’Greases, Editor Gabriela Wheeler reports that ExxonMobil’s Singapore Resid Upgrade Project (SURP) has reached mechanical completion and is on track to begin operations by late 2025.

The first-of-its-kind facility will add approximately 20,000 barrels per day of API Group II base stocks—including about 6,000 bpd of extra heavy product with kinematic viscosity of 32.5–35.5 mm²/s at 100 °C—designed to closely match traditional Group I bright stock viscosity while offering improved performance.

"As the first Group II plant to achieve viscosity typical of a Group I bright stock, the Singapore unit is poised to fill critical supply gaps," notes Wheeler in her analysis.
