14.7.3.42 IntervalStratigraphicUnits

Stereotypes:XSDcomplexType

A mapping from intervals to stratigraphic units for representations (grids or wellbore frames).

IntervalStratigraphicUnits does not allow multiple stratigraphic units per segment. To address this issue:

  • For wells: Add additional markers (one for each stratigraphic unit limit) and specify NaN for the measured depth that defines these markers' locations.
  • For Grids: Create a StratigraphicColumnRankInterpretation that groups together the stratigraphic units in the layer, then reference this rank from the IntervalStratigraphicUnits.

AbstractIntegerArray

Index of the stratigraphic unit per interval, of a given stratigraphic column.

Notes:

1.) For grids, intervals = layers + K gaps.

2.) If there is no stratigraphic column, e.g., within salt, use null (-1)

BUSINESS RULE: Array length must equal the number of intervals.
