12.17.13 ReferencePoint

Reference Point Component Schema.

Table 12.17.13-1 Attributes
Name	Type	Notes
Description	String2000	A textual description of the point.
ExtensionNameValue	ExtensionNameValue	Extensions to the schema based on a name-value construct.
MeasuredDepth	MeasuredDepthCoord	The measured depth coordinate of this reference point. Value is positive when moving toward the bottomhole from the measured depth datum. Provide a value for this when the reference is "downhole", such as an ocean-bottom template, or when the reference point is also used as a vertical well datum. The measured depth value can be used to determine if the reference pointand a vertical well datum are at the same point.
Name	String64	Human-recognizable context for the point.
Type	String64	The kind of point. For example, 'well reference point', 'platform reference point', 'sea surface', 'sea bottom'.
uid	String64	A unique identifier for an instance of a ReferencePoint.

Table 12.17.13-2 Associations
Association	Notes
From: ReferencePoint.Location 1..*To: AbstractWellLocation Association	Two dimensional coordinates that locate the point.
From: ReferencePoint.Elevation 0..1To: WellElevationCoord Association	The gravity based elevation coordinate of this point as measured from a datum. Positive moving upward from the elevation datum.
From: Well.ReferencePoint 0..*To: ReferencePoint Association	Defines a reference point within the context of the well.
