odpy.wellman.dblist

odpy.wellman.getNames(args={})

Gets survey well names from database

Parameters:

• args (dictionary, optional): Dictionary of optional parameters (see common).

  Default to None.

Returns:

• list: list of available survey wells from database

odpy.wellman.getInfo(wllnm, args={})

Gets information for a well

Parameters:

• wllnm (str): well name from survey

• args (dictionary, optional): Dictionary of optional parameters (see common).

  Default to None.

Returns:

• dict: information on well ID, name, x y cordinates, status etc

odpy.wellman.getName(dbkey, args={})

Gets well name

Parameters:

• dbkey (str): well database key

• args (dictionary, optional): Dictionary of optional parameters (see common).

  Default to None.

Returns:

• str: Well name

odpy.wellman.getLogNames(wllnm, args={})

Gets logs available for a well

Paramters:

• wllnm (str): name of well

• args (dictionary, optional): Dictionary of optional parameters (see common).

  Default to None.

Returns:

• list: list containing log names

odpy.wellman.getLog(wllnm, lognm, args={})

Get a well log from the OpendTect database Read a single log from the OpendTect database, without any depth resampling or unit conversion.

Parameters:

• wllnm (string): Well database name

• lognm (string): Log name as reported by getLogNames(wllnm)

• args (dictionary, optional): Dictionary of optional parameters (see common).

  Default to None.

Returns:

tuple: Two arrays with depths (MD) and log values

odpy.wellman.getLogs(wllnm, logidxlst, zstep=0.5, args={})

Get re-sampled logs from OpendTect

Parameters:

wllnm (string): Well database name logidxlst (string): List of log indices to be resampled zstep (double, optional): Resampling step in meters. Default to 0.5 args (dictionary, optional): Dictionary of optional parameters (see common).

Default to None.

Returns:

dict: Dictionary with log names as keys, logs as numpy arrays.

A depth array is also always output.

Example:

Get the logs from the well F03-4 with database indices 0, 1, 4, 6: >>> logs = odpy.wellman.getLogs( ‘F03-4’, ‘0`1`4`6’ )
