Abu Dhabi Onshore Oil Company (Adco) has extended the deadline to submit bids on the estimated $500-$600m second phase Qusahwira oil field development.

Pre-qualified firms have been given until 8 August to submit their technical bids for engineering, procurement and construction (EPC) contract. The initial bid submission deadline was 18 July.

The companies prequalifed 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)

MEED reported that Adco had cancelled a previous tender on the project to expand capacity of the Qusahwira field, after receiving technical EPC bids in June 2015.

Adco re-tendered the field development in June, changing its scope and pre-qualifying a different set of companies to bid on the project.

The second phase of Qusahwira forms part of the South East group of onshore concessions, which include the Mender and Sahil fields, which are set to produce 143,000 barrels a day contributing to eight per cent of Adco’s total output.

The main contract for phase one of the Mender field development was awarded to China Petroleum Engineering and Construction Corporation (CPECC) for $330m in 2015.

Pakistani firm Descon Engineering won the main contract for development of the Sahil field, which was also completed in 2015.

Sources familiar with the scheme say Chinese contractors who have worked previously on the project are likely to provide competitive prices on the project.

The scope of the Qusahwira Field Development is as follows:

  • 24 Well pads
  • 3 Gathering stations
  • 3 Water injection clusters
  • New gas injection compressors
  • New main oil line booster pumps
  • Water-disposal pumps
  • New water-alternating gas wells
  • Flow lines
  • Production separators
  • Flow metres
  • Major modification to the CDS
  • EPC of 75 wells

These onshore schemes are critical to boost Abu Dhabi’s plans to increase production capacity to 3.5 million b/d by 2020.
