The Norwegian Petroleum Directorate (NPD) has granted Wintershall and companions consent to start out manufacturing subsequent month from its Maria discipline within the Norwegian Sea.

The growth will come on stream virtually one 12 months forward of the unique plan, at decreased prices and with barely elevated oil reserves, NPD stated in a 16 November assertion. Production was initially scheduled to start out in This autumn 2018. The price estimate within the discipline’s plan for growth and operations (PDO) was US$1.9 billion (NOK 15.7 billion), however the precise funding has are available at simply over $1.four billion (NOK 12 billion).


“With a complete of 4 host amenities, the undertaking can be a very good instance of the worth creation generated from good collaboration with the licensees in surrounding infrastructure,” stated Kalmar Ildstad, NPD's assistant director for growth and operations within the Norwegian Sea, in a 16 November assertion.

Maria has been developed with two seabed templates, every with 4 slots. Current plans are to drill 4 oil manufacturing wells and two water injection wells. Maria is predicted to provide for 22 years. The discipline, situated in manufacturing licenses 475 BS and 475 CS within the Haltenbank space of the Norwegian Sea 240km northwest of Trondheim, about 20 km east of the Kristin discipline and about 45km southwest of the Heidrun discipline. Maria is Wintershall’s first operated growth undertaking off Norway.

The wellstream from Maria will likely be transported by way of a seabed pipeline to Kristin for processing and metering. The stabilized oil will then be routed to the Åsgard C – FSU for storage and offloading. The wealthy gasoline will likely be transported by means of the Åsgard Transport System (ÅTS) to Kårstø, the place NGL and condensate will likely be extracted. Gas for gasoline raise will likely be equipped from Åsgard B by way of the Tyrihans D template. Injection of sulfate-reduced water from Heidrun TLP will likely be used for stress assist.

Wintershall estimates whole recoverable reserves of 28.9 million customary cubic meters (Sm3) (181.eight MMboe) of oil, 1.32 million tonnes pure gasoline liquids (NGL) and a couple of.31 billion Sm3 gasoline. The discovery was initially estimated to include roughly 28.1 million Sm3 (176.7 MMboe) of oil equal, largely oil, but in addition some related gasoline and NGLs.

Maria was found in 2010; NPD accredited the Maria PDO in September 2015. Wintershall is operator with 50% curiosity. Partners are Petoro with 30% and Centrica Resources (Norge) with 20%.

Emerson at the moment (20 November) introduced that its newest Roxar Downhole Sensor System has been deployed on the Maria discipline offshore Norway, offering Wintershall with improved properly integrity monitoring and offshore security.

The wi-fi answer will ship essential integrity information and measures on-line and real-time stress and temperature data from behind the casing in subsea manufacturing wells. The stress and temperature monitoring system additionally permits Wintershall to confirm that the expected stress buildup falls throughout the design standards, and an alarm set off level is carried out in case pressures which are doubtlessly exterior the system design are reached.

The system additionally comes with new advances that allow operators to entry on-line shows and trending of beforehand unreachable temperature and stress subsurface information behind the properly casing and obtain on-line integrity verification with none impression on manufacturing. The system, that has been examined at 225 levels Celsius/437 levels Fahrenheit and may stand up to pressures of as much as 1 380 Bar/20 000 Psi,…
