Contractors have submitted revised commercial offers to Adnoc Onshore, a subsidiary of Abu Dhabi National Oil Company (Adnoc Group), for a project involving the tie-in of several wells in the Bab and North East Bab oil field developments in Abu Dhabi.

Located 84 kilometres southwest of the city of Abu Dhabi, the Bab field has been in production since 1960 and is the emirate’s first oil-producing asset. The North East Bab cluster comprises the Al-Nouf, Rumaitha and Shanayel fields. 

The One Tie-In project at the Bab and North East Bab field developments is integral to Adnoc Onshore’s contribution to its parent company Adnoc Group’s objective of achieving an oil production capacity of 5 million barrels a day (b/d) by 2027 – a campaign known as Accelerated Integrated Programme 5. The Abu Dhabi energy giant currently has a spare capacity of 4.85 million b/d.

According to sources, the following contractors are understood to be among those bidding for the project:

• Galfar Emirates (UAE branch of Oman’s Galfar Engineering & Construction)
• Jereh (China)
• Kalpataru Projects International (India)
• Matrix Construction (UAE)
• Robt Stone Middle East (UAE)
• Target Engineering Construction Company (UAE)

Adnoc Onshore is understood to have started the tendering process for the Bab and North East Bab One Tie-In project last year, with contractors submitting technical and commercial bids this year.

Following the evaluation of bids, Adnoc Onshore sought best commercial offers from the bidders, which contractors submitted earlier in May, sources told MEED.

Adnoc Onshore’s budget for the project is estimated to be $1.2bn, according to sources.

The broad scope of work on the project covers residual engineering, procurement of any material not part of free issued material, construction, site survey, installation, inspection and testing, pre-commissioning and commissioning support, to include new wellsite facilities, including a new mini-pad, well bay and cluster at the Bab and North East Bab field developments.
