Seven companies have been prequalified to bid to carry out the estimated $500m-$600m second-phase Qusahwira oil field development in Abu Dhabi.

Project owner Abu Dhabi Company for Onshore Petroleum Operations (Adco) has invited companies to submit bids for the engineering, procurement and construction (EPC) contract by 18 July.

The seven companies prequalified to bid are understood to be:

  • China Petroleum Engineering & Construction Corporation (CPECC; China)
  • Intecsa (Spain)
  • National Petroleum Construction Company (NPCC)
  • Petrofac (UK)
  • Saipem (Italy)
  • SK Engineering & Construction (South Korea)
  • Tecnicas Reunidas (Spain)

Project owner Adco cancelled a previous tender last year, having received technical EPC bids in June 2015, and is thought to have revised the scope of the scheme.

Adco will set a date for companies to submit prices after technical bids have been submitted and assessed.

Phase two of the Qusahwira field development is part of Adco’s programme to increase the capacity of its onshore South East Asset fields, which also includes projects at the Sahil and Mender fields.

Under the original scope, the expansion was expected to add 25,000 barrels a day (b/d) of new capacity at the field, which is located 260 kilometres south of Abu Dhabi city.

Canada’s SNC-Lavalin carried out the original front-end engineering and design (feed) study for the project.
