All material and images in the press kit are for free use for editorial purposes. 1.2 Det norske oljeselskap Det norske is a fully-fledged E&P company with exploration, development and production activities on the Norwegian Continental Shelf. We are building one of Europe’s largest independent E&P companies. Det norske is the operator for the producing fields Alvheim, Volund, Vilje and Jette. Det norske is also the operator of the development of the Ivar Aasen field, as well as partner in the Johan Sverdrup field. Det norske is partner in the enormous Johan Sverdrup field. Det norske has more than 500 employees. The company`s headquarters are located in Trondheim, with branch offices in Oslo, Stavanger and Harstad. Det norske is listed on Oslo Børs under the ticker “DETNOR”. 2 About Jette well Jette well spans three licenses, PL027D, PL169C and PL 504. Det norske is the operator with 70 percent interest. Petoro ASA is partner with 30 percent. Jotun B Illustration 1: Location of templates and pipelines at Jette.

DATE PAGE : 01 : 16.5.2013 : 4 of 6 A description The installation is on the seabed and consists of two production wells. Oil and gas from the wells will be transported from the two wells through two pipes, respectively 105 and 143 meters to a pipeline manifold (PLEM - Pipeline End Manifold). The oil will further be transported in a six kilometer pipeline to the Jotun B installation. In addition there will be a six kilometer cable (umbilical) from Jotun B to a subsea distribution unit (SDU) at Jette. There are both electrical and hydraulic cables, as well as gas from the distribution unit to the two Jette wells. The gas is used to increase the pressure and thus lift the oil up through the well. 2.2 Location The Jette field consists of two small separate oil accumulations, Jette north and Jette south. The two wells are located in block 25/7 and 25/8, 180 km west of Haugesund, and six kilometers south of the Jotun field. Water depth in the area is approximately 127 meters.

No deposits of coral and sponge environments. There may be seabirds in the area. The deposits on the sea will be spread. Environmental risk is assessed to be low and acceptable. There are several species of fish that spawn in this part of the North Sea, mainly during spring. Jette is within the spawning area for pollock. The mackerel spawns during summer (May-July), but spawning areas are located much further south in the North Sea. All relevant species in the area spawn pelagic and over large areas. Environmental risk to fish is very low. It may sometimes be small and larger groups of whales in the area. Jette is an oil reservoir with Jotun Tau oil. This is a paraffinic oil with a high wax content. Reservoir fluid will contain some gas which will be released by a possibly emissions. It is not identified specific challenges in this area that hampers mechanical or chemical control. Weather statistics shows that the significant wave height is less than 4 m Hs, respectively 89 percent, 98 percent, 85 percent and 75 percent of the time during spring, summer, autumn and winter season. The oil is dispersible, but has low potential for dispersal. The use of dispersants is included as a supplement to mechanical control. • Emergency preparedness systems at Jotun /Balder may be mobilized within two hours, with both mechanical and chemical control. Rented towing vessels will be used if necessary (standby vessels and supply vessels), tugboats from NOFO (supply vessels and fishing vessels) and rescue boats. An oil spill will most likely not arrive coastal areas (probability of 5 to 10 percent, some areas 10 to 15 percent), and drift time to the coastline is long. There are therefore no response time requirements for mobilization of oil spill systems in the coastal zone.
