• Description

  Meile Member (informal)
  
  Name

  Meile was a son of the Norse god Odin. Little is told about him except that he was one of 3 messengers from the gods to save Balder from Hel (hell in Norse mythology).

  Well reference section

  Norwegian well 15/9-11 from 2526 m to 2386 m, coordinates N 58°24'02.53", E 01°53'41.79" (Fig 5.51) .

  Thickness

  The Meile Member is 140 m thick in the reference well. It has a relatively constant thickness.

  Lithology

  The Meile Member consists of clean, well-sorted sandstones, which are very fine to fine grained, friable to hard, and clear to white.

  Basal stratotype

  The lower boundary of the Meile Member is defined by the transition from the marly claystones of the Våle Formation . The gamma and sonic logs change from an erratic pattern in the Våle Formation to a smooth pattern with low gamma-ray readings when passing into the Meile Member (Fig 5.57) . Where the Våle Formation is absent the Meile Member rests directly on the calcareous deposits of the chalk facies of the Shetland Group . This boundary is characterised by upward increasing gamma-ray readings and decreasing velocity (Fig 5.51) .

  Characteristics of the upper boundary

  The upper boundary is identified by a transition from clean sandstones into the shales of the Lista Formation . On the logs the upper boundary is seen as an increase in gamma-ray values and a change to a more erratic log pattern on both gamma and sonic logs (Fig 5.51) .

  Distribution

  The Meile Member is found in a narrow belt extending north-northeastwards from the eastern part of quadrant 15. Its approximate distribution on the Norwegian continental shelf is shown in (Fig 5.47) .

  Age

  Paleocene.

  Depositional environment

  The clean sandstones of the Meile Member may have been derived by winnowing of the Heimdal Formation sands by submarine currents acting along highs. The formation can also be interpreted in terms of high-density turbidites which source from well-sorted shelf sand.

  Remarks

  The Meile Member has earlier informally been referred to as the “Gamma sand on Sleipner”. The Meile Member is defined informally.
