Vallourec has been awarded a contract to supply premium tubes and connections for the ultradeep offshore Kaombo project in Angola, operated by Total E&P Angola, a news release said.

As part of this contract, Vallourec will supply 27,000 tons of oil country tubular goods (OCTG) for wells drilled within 1,400 m (4,593 ft) to 2,000 m (6,562 ft) water depth and reaching up to 5,000 m (16,404 ft) drilling depth. The Kaombo oil field is located 150 km (93 miles) off the Angolan coast.

The Kaombo project is composed of 59 wells to be drilled in a variety of complex geologies, requiring different types of well design with their contingency. A third of the wells target subsalt reservoirs, which require drilling through salt layers to reach target depth. Vallourec will supply its most advanced premium tubular solutions, including VAM 21 connections combined with integral premium connections (VAM® SLIJII and VAM® BOLT), the release said.

Casing and tubing products will be manufactured and finished in France, Indonesia and Brazil. Manufacturing of the first batches will be completed in December 2014. Drilling operations will start in third-quarter 2015 and are expected to last until 2021.
