World's Longest Electrically Heated Flowline Allows HP/HT Field Tieback to Existing Host

摘要

The Linnorm gas/condensate field in the Norwegian Sea is technically challenging. The high-pressure/high-temperature (HP/HT) reservoir contains gas with CO2, H2S, and traces of mercury. Although the gas is relatively lean, the associated condensate has waxy properties. Although there are production facilities within 30 to 70 km, this discovery was initially seen as "stranded" gas because of the absence of an export route with available capacity. The wells and subsea concepts would push the limits of existing technology and require some world-first solutions for what will be the highest-temperature subsea field development on the Norwegian continental shelf with the world's longest electrically heated flowline.
