Norway’s Barents Sea uses
Un estudio reciente reclama mejoras tecnológicas para reducir los costes para la evolución del Mar de Barents
Neue Studie fordert technologische Verbesserungen zur Reduzierung der Kosten für Projekte in der Barentssee
N
orway’s OG21 recently received the DNV GL study of technologies that should be developed for year-round oil and gas production at 74 degrees
North in the Norwegian Barents Sea. New licenses are due to be awarded in this area as part of the Norwegian 23rd licensing round. T e report concludes that technology solutions are fairly mature, but need to be adopted for Norwegian waters. T is would be possible within an eight to 10 year timeframe, which is also the earliest one can expect fi rst oil or gas in the licenses. “We have identifi ed close to 30 challenges to enable year-round oil and gas production in the area,” says DNV GL Oil & Gas divisional director for Europe and Africa, Liv Hovem. “To improve the business case for developments in this part of the shelf, key enhancing technologies within drilling, including large bore wells, as well as reservoir performance, gas compression, subsea facilities and power supply are
important to mature. Many leading companies are already well underway to develop these technologies, but more needs to be done to make year round production in eight to 10 years realistic.”
TECHNOLOGY HELPS CUT COSTS “T ese enhancing technologies also strengthen the business case for fi eld developments in the area, through increased recovery or reduction in capex or opex,” says Per Olav Moslet, DNV GL – Oil & Gas senior principal engineer, and an expert on Arctic technologies. “T ese locations are among the
northernmost locations that are open for petroleum activities in Norway. As the study shows, some elements of the physical environment are more demanding than elsewhere on the NCS, for example the possibility of ice, marine icing, polar lows and fog, while other elements such as waves and wind, are less severe. T e study also shows that fairly mature technologies that can solve these challenges are underway,” says Moslet. T e study was carried out in close cooperation with OG21 and its Technology Target Area groups. T e technologies have been assessed based on three potential fi eld development scenarios: oil production from an FPSO in the south-western Barents Sea; subsea oil production in the south-western Barents
TECH TO CUT COSTS Recent study calls for technology improvements to reduce costs for Barents Sea developments
Sea; and gas production from an FPSO in the south-eastern Barents Sea.
OPERATIONS IN SIMILAR ENVIRONMENTS “T ere are already operations in similar environments in other places in the world, such as in the Sakhalin area in Russia and Grand Banks, Canada. T is means that some technologies from these areas can also be adapted for use in these areas on the NCS,” explains Moslet. In addition to the fi ve technologies for cost cutting and production enhancement above, 11 technologies and technology areas that need to be matured in the same timeframe to facilitate operations in this area have also been identifi ed:
● Escape, evacuation and rescue infrastructure
● Environmental risk models ● Detection and monitoring technology of oil in and under ice
● Ice detection, forecasting, surveillance systems
● Ice handling systems ● Same season relief well capability ● Ice load prediction models ● Escape, evacuation and rescue technology
● Oil spill response technology ● Personal protection and emergency equipment
● Winterisation solutions ●
