Statoil outlines offshore Troll natural gas redevelopment

By OGJ editors

Statoil and its partners plan to invest 11 billion kroner in two new compressors on Troll A platform in the North Sea to enable natural gas production with reduced wellhead pressure and to extend the life of the field.

The new compressors are expected to extend gas production from the field until 2063.

New compressors also pave the way for the tie-in of gas from Troll West once oil production ends. The two compressors are scheduled to come on stream in 2015, enabling Troll A to produce 120 million cu m/day until 2018 and 30 billion cu m/year until 2024.

Hans Jakob Hegge, Statoil senior vice-president for operations North Sea east, said Troll A accounts for one third of all gas capacity on the Norwegian Continental Shelf.

Statoil awarded Aibel a 2.7 billion kroner contract for modules and modifications for two new precompressors. Aibel will provide engineering, procurement, onshore construction, and integrated offshore construction and completion work to upgrade Troll A’s precompression capacity.

The work was scheduled to start immediately, with offshore installation starting in 2012.

The Future of US Refining

When Fri, Feb 6, 2015

Oil & Gas Journal’s Feb. 6, 2015, webcast will focus on the future of US refining as various forces this year conspire to pull the industry in different directions. Lower oil prices generally reduce feedstock costs, but they have also lowered refiners’ returns, as 2015 begins with refined products priced at lows not seen in years. If lower per-barrel crude prices dampen production of lighter crudes among shale plays, what will happen to refiners’ plans to export more barrels of lighter crudes? And as always, refiners will be affected by government regulations, particularly those that suppress demand, increase costs, or limit access to markets or supply.
