• Description

  Åsgard Formation
  
  Name

  Named from Norse mythology after the castle of the Norse gods, where Odin ruled.

  Well type section

  Norwegian well 2/11-1 from 3555 m to 3063 m, coordinates N 56°14'16.98", E 03°27'07.05" (Fig 5.12) . No cores.

  Well reference sections

  Norwegian well 17/11-2 from 2410 m to 1802 m, coordinates N 58°06'54.91", E 03°22'09.81" (Fig 5.13) . No cores.
  Danish well I-1 from 3358 m to 2986 m, coordinates N 56°03'10", E 04°14'60" (Fig 5.14) . No cores.

  Thickness

  The formation is 492 m thick in the type well and 608 m thick in reference well 17/11-2 .
  In the Central Trough area the thickness varies from a few metres to more than 500 m over short distances, showing the complex pattern of small, restricted Early Cretaceous basins. An even thicker sequence was penetrated in the Norwegian-Danish Basin, and especially in the Åsta Graben, where more than 700 m were encountered in well 17/12-3 . The formation is thickest in the Sogn Graben where it is probably more than 1200 m, as indicated by seismic data.

  Lithology

  The formation is dominated by light to dark grey, olive-grey, greenish and brownish, often calcareous claystones, and passes into light grey, light greenish-grey and light olive-grey marlstones and stringers of limestone. Mica, pyrite and glauconite are common. The claystones may be silty, and siltstones or very fine-grained sandstone layers or laminae are present. Where major sandstone layers occur they are regarded as belonging to the Ran sandstone units. In a few Norwegian wells in the central North Sea (e.g. 1/9-3 R , 2/3-1 , 2/7-2 , 2/10-1 S , 2/11-1 , 7/3-1 , 7/8-2 , 7/12-4 , 7/12-5 and 8/1-1 ) a sequence of calcareous claystone, marlstone and limestone interbeds is recognised as the basal part of the Åsgard Formation (Fig 5.12 , 5.14) . This sequence is very difficult to correlate in the Norwegian sector, even over small distances, and is therefore regarded as representing local variations in the lowermost part of the Åsgard Formation. In the Danish sector this sequence is defined as the Leek Member (Jensen et al. 1986).

  Basal stratotype

  The lower boundary is defined by a marked upward decrease in gamma-ray response and an increase in velocity in areas where the underlying sediments are slightly to non-calcareous, organic-rich claystones and shales, usually belonging to the Mandal , Flekkefjord , Tau or Draupne formations (Fig 5.15 , 5.22). Where the claystones and shales are less organic rich and more calcareous, the boundary may be more difficult to identify on logs.

  Characteristics of the upper boundary

  The characteristics of the upper boundary vary with the overlying formations. Where the Tuxen Formation occurs, the boundary is defined by an upward decrease in the gamma-ray readings and an increase in velocity, reflecting slightly more calcareous claystones, marlstones and limestones compared with the underlying Åsgard Formation (Fig 5.14 , 5.15). Where the Tuxen Formation is missing and the Sola Formation is deposited on the Åsgard Formation, the boundary is defined by an upward increase in gamma-ray readings and a decrease in velocity (Fig 5.17 , 5.18 , 5.23). If both the Tuxen and Sola formations are missing, the boundary to the overlying Rødby Formation is defined by an upward decrease in gamma-ray readings and an increase in velocity. Locally, the Åsgard Formation is overlain by the Ran sandstone units (Fig 5.22) ., and the Agat Formation (Fig 5.19 , 5.20). This boundary is defined by an upward decrease in gamma-ray readings.

  Distribution

  The Åsgard Formation is very widespread in the North Sea (Fig 5.7 , 5.8 , 5.9 , 5.10 , 5.11) , as are the partial equivalents in the Danish sector (Valhall Formation), British sector (Speeton Clay) and Dutch sector (Vlieland Shale Member). In the Norwegian sector, the formation is absent from the highest parts of the Mandal, Jæren and Utsira highs, the Lomre Terrace, the Troll area, Tampen Spur and locally over salt pillows and diapirs in the Central Trough and the Norwegian-Danish Basin.

  Age

  Where the Tuxen Formation occurs, the Åsgard Formation ranges in age from Late Ryazanian to Late Hauterivian. In areas where neither the Tuxen nor Sola formations are recognised, the Åsgard Formation represents a lateral equivalent and may reach Late Aptian to Early Albian age.

  Depositional environment

  The formation was deposited in an open marine, low-energy shelf environment with well-oxygenated bottom water.

  Remarks

  Deegan and Scull (1977) divided the Cromer Knoll Group into the Rødby and Valhall formations. Several lithostratigraphic units have later been described in the Vallhall Formation (Hesjedal & Hamar 1983, Jensen et al. 1986). The remaining claystones and marlstones of the originally defined Valhall Formation constitute the Åsgard Formation.
