Tengiz is the sixth largest oil field in the world located in northwestern Kazakhstan's low-lying wetlands along the northeast shores of the Caspian Sea.

It covers a 2,500 km2 project license area which also includes a smaller Korolev field as well as several exploratory prospects.

The city of Atyrau, 350 kilometres north of Tengiz, is the main transport hub of Tengiz oil.

Scope of work

The scope of work is the construction and pre-commissioning of about 377 k of various diameters pipelines.

The project includes:
 

  • a new gathering system for transporting the fluids of Tengiz and Korolev reservoir to the new FGP processing facilities
  • high pressure sour gas injection and utilities (water, fuels. Gas and diesel)

Being located in an operational field, the activities will be executed in particularly challenging conditions such as brownfield and characterized by an elevated number of crossings which is estimated in about 3800 between Pipelines, Buried Cables, Areal Cables, Roads and SOE Areas.
