Member Function Documentation

◆ ComputeStep()

static double ComputeStep ( LasCurve lasCurve )

static

Compute the step of the specified LAS (index) curve.

Parameters

lasCurve LAS curve to compute step of.

Returns: The requested step value. 0.0 if irregular.

Exceptions

ArgumentNullException If lasCurve is null.

◆ FindStep()

static double[] FindStep ( LasCurve lasCurve )

static

Find actual step value of the specified LAS (index) curve, being the distance between values in the curve.

Three values are returned: The minimum step, the maximum step and the average step. It is left to the client to decide if these numbers represents a regular or an irregular log set.

Parameters

lasCurve LAS curve to find step from. Non-null.

Returns: The (minimum, maximum and average) step value of the LAS curve.

Exceptions

ArgumentNullException If lasCurve is null.

◆ GetBitSize()

static ? double GetBitSize ( LasFile lasFile )

static

Return bit size of the specified LAS file.

Parameters

lasFile LAS file to get bit size from. Non-null.

Returns: Bit size of LAS file (in meters according to the LAS documentation), or null if not found.

Exceptions

ArgumentNullException If lasFile is null.

◆ GetCompany()

static string GetCompany ( LasFile lasFile )

static

Return company name of the specified LAS file.

Parameters

lasFile LAS file to get company name from. Non-null.

Returns: Company name of LAS file, or null if not found.

Exceptions

ArgumentNullException If lasFile is null.

◆ GetCountry()

static string GetCountry ( LasFile lasFile )

static

Return country of the well of the specified LAS file.

Parameters

lasFile LAS file to get country from. Non-null.

Returns: Country of well of LAS file, or null if not found.

Exceptions

ArgumentNullException If lasFile is null.

◆ GetDate()

static ? DateTime GetDate ( LasFile lasFile )

static

Return logging date from the specified LAS file.

Parameters

lasFile LAS file to get logging date from. Non-null.

Returns: Logging date of LAS file, or null if not found.

Exceptions

ArgumentNullException If lasFile is null.

◆ GetFieldName()

static string GetFieldName ( LasFile lasFile )

static

Return field name of the specified LAS file.

Parameters

lasFile LAS file to get field name from. Non-null.

Returns: Field name of LAS file, or null if not found.

Exceptions

ArgumentNullException If lasFile is null.

◆ GetInterval()

static double[] GetInterval ( LasFile lasFile )

static

Get logging interval of the specified LAS file.

NOTE: This is the interval specified by the start/stop parameters in the well section, not the actual interval from the file data (which may well be different).

Parameters

lasFile LAS file to get interval from. Non-null.

Returns: The logging interval of the LAS file. Array of two (smallest value first) or null if property not found.

Exceptions

ArgumentNullException If lasFile is null.

◆ GetMd()

static ? double GetMd ( LasFile lasFile )

static

Return MD (measured depth) of the specified LAS file.

Parameters

lasFile LAS file to get MD from. Non-null.

Returns: MD of LAS file, or null if not found.

Exceptions

ArgumentNullException If lasFile is null.

◆ GetRigName()

static string GetRigName ( LasFile lasFile )

static

Return rig name of the specified LAS file.

Parameters

lasFile LAS file to get rig name from. Non-null.

Returns: Rig name of LAS file, or null if not found.

Exceptions

ArgumentNullException If lasFile is null.

◆ GetRunNumber()

static string GetRunNumber ( LasFile lasFile )

static

Return run number of the specified LAS file.

Parameters

lasFile LAS file to get run number from. Non-null.

Returns: Run number of LAS file, or null if not found.

Exceptions

ArgumentNullException If lasFile is null.

◆ GetServiceCompany()

static string GetServiceCompany ( LasFile lasFile )

static

Return service company name of the specified LAS file.

Parameters

lasFile LAS file to get service company name from. Non-null.

Returns: Service company name of LAS file, or null if not found.

Exceptions

ArgumentNullException If lasFile is null.

◆ GetStep()

static ? double GetStep ( LasFile lasFile )

static

Get logging step of the specified LAS file.

NOTE: This is the interval specified by the step parameters in the well section, not the actual interval from the file data (which may well be different).

According to the LAS specification the step value is -1.0 in case the actual step is irregular or unknown.

Parameters

lasFile LAS file to get logging step from. Non-null.

Returns: The step of the LAS file. Null if it is not present.

Exceptions

ArgumentNullException If lasFile is null.

◆ GetWellName()

static string GetWellName ( LasFile lasFile )

static

Return well name of the specified LAS file.

Parameters

lasFile LAS file to get well name from. Non-null.

Returns: Well name of LAS file, or null if not found.

Exceptions

ArgumentNullException If lasFile is null.

◆ IsTimeIndexed()

static bool IsTimeIndexed ( LasFile lasFile )

static

Check if the specified LAS file is time indexed.

A LAS file is defined to be time indexed if the start and stop parameters (STRT/STOP) have time units.

Parameters

lasFile LAS file to check. Non-null.

Returns: True if the LAS file is time indexed, false if it is depth indexed, or the indexing is not specified.

Exceptions

ArgumentNullException If lasFile is null.

◆ ToString()

static string ToString ( LasFile lasFile )

static

Create a string representation of the entire content of the specified LAS file.

Parameters

lasFile LAS file to get as string. Non-null.

Returns: A string representation of the LAS file. Never null.

Exceptions

ArgumentNullException If lasFile is null.
