Shtokman is one of the world’s largest offshore gas fields. Estimated resources are 3.8Tcm of gas and 37MMcm of gas condensate. The field is located in the Russian Barents Sea, 338 nm from Kirkenes and about the same distance from Murmansk, in 320-340m water depth.
Seven wells have been drilled and thorough investigations of different kinds have been conducted. Different concept studies have also been made.
The most recent and detailed study was carried out by Shtokman Development AG, a consortium comprising Gazprom, Total, and Statoil. This study concluded with a technical solution based on a disconnectable FPSO at the field, with loading of gas condensate at the field and pipe transport of the gas to Teriberka, 136km east of Murmansk. From there, part of the gas would be piped to St. Petersburg and part processed into LNG for export.
This concept did result in acceptable economics and led to no investment decision.
Further development favors production of LNG only. The former partners of the SDAG continue to study improved concepts.
