South Korean contractor Hyundai Engineering & Construction (Hyundai E&C) is on track with construction of gas treatment units at Saudi Aramco’s Uthmaniyah gas project.

Aramco awarded the main engineering, construction and procurement (EPC) contract to Hyundai E&C in October 2016 for $727m to build the units, which include an ethane recovery plant and a natural gas-to-liquids (NGL) plant.

“Construction is on track and is progressing according to plan,” a source close the project said.

The contractor expects to finish the job by November 2019, the scheduled completion period.

Australia-based engineering firm WorleyParsons has done the front-end engineering and design (feed) work on the project.

The project’s objective is to recover ethane, propane and other NGLs from the 1.4 billion standard cubic feet a day of sales gas that Uthmaniyah produces.

The gas treatment units will also process associated gas produced from the Ghawar field – the world’s largest onshore oil field based on reserves.
