Abu Dhabi National Oil Company (Adnoc) has delayed the bid process for a substantial offshore contract that involves work on the long-term development phase of its giant Umm Shaif oilfield — a key component in the emirate's ambitious oil output capacity increase plans.

Several people familiar with the development told Upstream that the tender process for the first phase of Umm Shaif long term development project (LTDP-1) is set to be delayed by months, with the project’s award now likely to slip into 2022.
