Heating System Providing Skin Effect Heating Systems for the Kharyaga Oil–Field in Siberia
Bartec delivered skin effect heating systems into the Kharyaga field, providing engineering, calculation, design, supply, installation, commission, and supervision in frozen Siberian. The target was to assure frost protection and temperature maintaining at the long transfer pipe lines of the oil field in the oil-rich Nenets tundra.
The Kharyaga oil field in Western Siberia, with overall oil reserves estimated to 160 million tons, epitomizes the difficulties of Arctic and extreme-cold regions: isolation, extreme weather conditions, and a fragile ecosystem.
Yet some years of uninterrupted production have demonstrated the validity of the solutions conceived by Total who, together with StatOil and the Nenets Oil Company, operate the Kharyaga oil field near the Barents Sea. The Russian government approved this joint venture in 1999. In 2009, Bartec started to work on the Kharyaga phase III development project.
Despite the harsh conditions some 60 kilometers north of the Arctic Circle — remote location, winter temperatures down to -46 °C and very strong winds — production at Kharyaga has continued uninterrupted for years, thanks to a number of specific measures: By drilling with deviated wells from a limited number of pads away from a central processing station the impact of surface installations is minimized.
To prevent plugging the waxy oil is maintained at +40 °C. All facilities use high-performance insulation and Bartec’s skin effect heating systems. A first oil line between the North Pad and the central facility had 10,4 kilometers length. Another line for a second pad in the East followed fastly. Empty caves in the earth are filled with +60 °C warm water. Workspaces are enclosed and heated to protect workers and equipment with ventilation for confined areas due to explosion risks. During phase III development, heat recovery units will be installed on the new gas turbines as an energy efficiency measure.
