Noble picks Tenaris for Alen gas offshore pipeline construction in Equatorial Guinea

U.S. oil and gas company Noble Energy has chosen the tubes supplier Tenaris for the construction of the Alen gas monetization project offshore pipeline in Equatorial Guinea. 

This 70 km pipeline will be constructed to transport natural gas from the Alen offshore platform to existing onshore processing facilities on Bioko Island, Tenaris said in its statement.

Tenaris will produce a total of 21,000 metric tons of line pipe at its Confab welded pipe mill located in Pindamonhangaba, Brazil.

Noble Energy said in an earlier statement it plans to process the natural gas from the Alen field through the existing Alba Plant liquefied petroleum gas processing plant and EG LNG’s liquefied natural gas production facility at Punta Europa, Bioko Island.

The Alen gas monetization project will utilize the existing three high-capacity production wells on the platform, with minor modifications necessary to deliver sales gas from the platform to the Alba Plant and EG LNG facilities.

At start-up, natural gas sales from the Alen field are anticipated to be between 200 and 300 mmcfe/d. Total estimated gross recoverable resources from the Alen field are approximately 600 billion cubic feet of natural gas equivalent.

Noble Energy operates the Alen field and holds an approximate 45 percent working interest in the project. Partners in the field are Glencore, GEPetrol, Atlas, and Gunvor.

The company holds a 28 percent working interest in the Alba Plant which is operated by Marathon Oil. The EG LNG facility is also operated by Marathon Oil, but Noble holds no working interest in the facility.
