Norway's Draugen platform, located off the northern coast of Norway in the North Sea, has played a significant role as an oil-producing facility since its discovery in 1984. The field was brought into production during this time period due to advancements made in drilling and extraction technology.

The main reservoir at Draugen contains sandstone from the Rogn formation, which is believed to be of late Jurassic age based on geological surveys conducted by experts. This particular layer of rock has proven rich in oil reserves that have been tapped since operations began at the site.

In addition to this primary source, another deposit known as the Garn formation located further west also contributes significantly towards Norway's overall oil output from Draugen field. The Garn reservoir is thought to be approximately 30 million years older than its counterpart, with age estimates suggesting it dates back to middle Jurassic times.

Despite being situated at considerable depths beneath sea level - precisely 1,650 meters below surface - both the Rogn and Garn formations are found in relatively similar geological conditions, making them easier for extraction purposes. The fact that these two deposits share identical characteristics makes their exploitation more cost-effective compared to dealing with dissimilar rock types.

As of December 31st, 2009, total recoverable oil reserves at Draugen were estimated to stand at an impressive 145 million standard cubic meters (m3). Meanwhile, the remaining unexploited reserve potential was put at a staggering 19.7 billion m³ - figures that underline just how substantial this particular field remains even after decades of production activity.

However, despite its significant contributions towards Norway's energy sector over the years, operations at Draugen faced an unexpected halt in February 2010 due to extreme weather conditions prevalent during that period. Strong winds and sub-zero temperatures made it unsafe for continued operation, forcing Shell - which holds operatorship rights for the facility - to temporarily suspend activities until more favorable climatic circumstances returned.

Since then, there have been no official announcements from relevant authorities regarding a possible resumption of drilling operations at Norway's Draugen platform. The future remains uncertain for this vital oil-producing asset in light of changing global market conditions and environmental concerns that continue to shape the course of energy production across various regions worldwide.
