State oil giant Saudi Aramco is looking for firms to manage the construction of the Jizan refinery, industry sources said on Saturday.

Engineering firms will have to submit their prequalification documents, which also include the front-end engineering and design (FEED) and project management services (PMS) by June 12, sources said.

The refinery, with a planned capacity of 250,000-400,000 bpd is among new plants Saudi Arabia is planning to build as it looks to boost domestic refining capacity.

'Aramco is still evaluating options to decide on the capacity of the refinery,' an industry source told Reuters.

In January, Saudi Arabia said Aramco would build the refinery at Jizan.

The kingdom had hoped the refinery would be built and owned entirely by the private sector, a first in the world's top exporter.

The refinery is far from Saudi Arabia's producing fields and is part of a wider development plan for the impoverished southern region. – Reuters
