Abu Dhabi Company for Onshore Petroleum Operations (Adco) has started the pre-qualification process for a key engineering, procurement and construction contract at its giant Bu Hasa onshore oilfield.

The Bu Hasa integrated facility project (BIFDP) aims to increase crude production from 540,000 barrels per day to 570,000 bpd, industry sources said.

A sizeable group of leading EPC players are expected to line up for the pre-qualification process, with a formal tender expected to be issued to eight to 10 short-listed players by the second half of this year, sources added.
