At least four contracting giants are battling it out for the further expansion of QatarEnergy's Idd El-Shargi North Dome (ISND) oilfield project in the Persian Gulf.

Multiple people familiar with the tender process told Upstream that commercial bids for the much-delayed tender are likely to be submitted on 12 March by up to four leading international contracting giants or consortia.

“The operator recently revealed the bid submission deadline for the ISND project, after delaying the process for several months,” one person noted.
