As per the agreement, Jacobs will provide FEED services for both inside battery limits (ISBL) and outside battery limits (OSBL).

The ISBL services include a new lube oil unit, a new sulfur complex, and an expansion of the propane de-asphalting unit; and the OSBL services involve all utilities and infrastructure, Jacobs said.

The company expects that the Yanbu Refinery expansion will increase base oil production and double the current production of GR-I Bright stock; produce higher-value byproducts; and satisfy Saudi Arabia’s requirements for drilling fluid.
