Abstract

The Arctic region is believed to be one of the most important remaining petroleum provinces. As part of the Arctic potential, the Barents Sea represents an opportunity to develop a new European petroleum province. This paper is focused on the Fedyn Arch in the former disputed area, which potentially is one of the biggest gas fields in the Barents Sea. The paper starts by outlining the Barents Sea geological conditions to make an overall picture of potential hydrocarbon reserves of this area. Hydrocarbon transportation scenarios of the Fedinskiy High field development will be discussed taking into account suitable sites for a potential onshore treatment terminal and potentially an LNG plant. Depending on various factors the question of transport solution becomes significant, and its costs could reach billions of dollars. One of the most costeffective solutions for the development of offshore fields is the use of subsea to shore concept. The objective of the study is to analyze how a flow rate variation in a gas condensate system influences the water accumulation (HOLDUP) along the pipeline as well as on flow regime changes and overall pressure loss. Possible scenarios of arrival facilities are discussed in detail based on existing and planned onshore infrastructures. According to the suggested scenarios multiphase simulation will be carried out by the OLGA simulator. Due to special environmental conditions (potential sub-zero temperatures at the seabed) in the Arctic regions, such as in the Barents Sea, it is important to consider the risk of hydrate formation along the pipeline.
