12.7.6 DepthRegLogSection

Topic Version1Published11/11/2016
For StandardWITSML v2.0
Type:ClassStereotype:«XSDcomplexType»

Defines the description and coordinates of a well log section, the curves on the log. An important XSDelement to note is log:refNameString; it is a reference to the actual log/data (in a WITSML server) that this raster image represents; this object does not contain the log data.

Name

Type

Notes

CalibrationPoint

DepthRegCalibrationPoint

Generally this associates an X, Y value pair with a depth value from the log section.

Comment

String2000

Comments about the calibration.

ExtensionNameValue

ExtensionNameValue

Extensions to the schema based on a name-value construct.

IndexReference

WellboreDatumReference

The origin for vertical coordinates on the original log. If this is not specified, information about the datum should be specified in a comment.

IndexType

LogIndexType

Primary index type. For date-time indexes, any specified index values should be defined as a time offset (e.g., in seconds) from the creationDate of the well log.

IndexUom

String64

Index UOM of the original log.

Log

Log

The ID of the log being referred to by this section.

LogMatrix

String64

Log matrix assumed for porosity computations.

LogSectionName

String64

Name of a log section; used to distinguish log sections of the same type.

LogSectionRect

DepthRegRectangle

The bounding rectangle of this log section.

LogSectionSequenceNumber

NonNegativeLong

Zero-based index in the log sections, in order of appearance.

LogSectionType

LogSectionType

Type of log section.

LowerCurveScaleRect

DepthRegRectangle

Boundaries of the lower curve scale (or horizontal scale) section for this log section.

MaxInterval

GenericMeasure

Maximum of the range of the index values. '@uom' must be consistent with '//indexType'.

MinInterval

GenericMeasure

Minimum of the range of theindex values. '@uom' must be consistent with '//indexType'.

ScaleDenominator

GenericMeasure

The denominator of the index (depth or time) scale of the original log, e. g. "100 ft". '@uom' must be consistent with '//indexType'.

ScaleNumerator

LengthMeasure

The numerator of the index (depth or time) scale of the original log, e. g. "5 in".

uid

String64

Unique identifier for the log section.

UpperCurveScaleRect

DepthRegRectangle

Boundaries of the upper curve scale (or horizontal scale) section for this log section.

VerticalLabel

String2000

Vertical log scale label (e.g., “1 IN/100 F”).

VerticalRatio

String2000

Second term of the vertical scale ratio (e.g., “240” for a 5-inch-per-100-foot log section).

WhiteSpace

DepthRegRectangle

Defines blank space occurring within a log section in an image.
