cegalprizm.pythontool.LogSamples
objectReturns the Petrel template for the object as a string.

- add_comment(new_comment: str, overwrite: bool = False) None #
Add a comment to the already existing comments on the PetrelObject, or overwrite the existing comments.
- Parameters
new_comment – The new comment to add to the PetrelObject.
overwrite – Boolean flag to overwrite all existing comments with the new comment. Default is False.
- Raises
PythonToolException – if object is read-only
- as_dataframe() pandas.core.frame.DataFrame #
The values of the log as a Pandas DataFrame
This method is only available in CPython.
- clone(name_of_clone: str, copy_values: bool = False, discrete_template: Optional[cegalprizm.pythontool.template.DiscreteTemplate] = None) cegalprizm.pythontool.welllog.DiscreteWellLog #
Creates a clone of the discrete well log.
The clone is placed in the same collection as the source discrete well log. A clone cannot be created with the same name as an existing Petrel object in the same collection.
A clone can be created with a DiscreteTemplate. Cloning with a discrete_template is only possible if copy_values=False. When cloning with discrete template, the clone will get the default color table of the given discrete template. If a discrete_template argument is not provided, the clone will have the same discrete template and color table as the source object.
- Parameters
name_of_clone (str) – Petrel name of the clone
copy_values (bool) – Set to True if values shall be copied into the clone. Defaults to False.
discrete_template – DiscreteTemplate to use for the clone. Defaults to None.
- Returns
The clone
- Return type
- Raises
Exception – If there already exists a Petrel object with the same name
ValueError – If name_of_clone is empty or contains slashes
UserErrorException – If both copy_values=True and discrete_template is used as arguments. Can only clone with discrete_template if copy_values=False
UserErrorException – If discrete_template is not a DiscreteTemplate object
- get_template() Optional[Union[cegalprizm.pythontool.template.Template, cegalprizm.pythontool.template.DiscreteTemplate]] #
Returns the Petrel template for the object as a Template or DiscreteTemplate object
- retrieve_history() pandas.core.frame.DataFrame #
The Petrel history for the object.
Returns the Petrel history for the object as Pandas dataframe.
- Returns
The history of the object as reported by Petrel
- Return type
DataFrame
- retrieve_stats() Dict[str, str] #
Retrieves a dictionary summarizing the statistics for the object
The statistics are a snapshot of the information in the Statistics page of the Settings panel of the object in the Petrel tree. Both the dict key and value are strings, and may contain punctuation, English phrases or just filler information. Any changes to the dict returned will not be saved or affect anything.
Note: this operation may be slow, since the statistics are ‘live’ - they represent the most up to date information.
- Returns
The statistics of the object as reported by Petrel
- Return type
dict
- set_values(mds: List[float], values: List[Optional[float]])#
Replaces all the log samples with the supplied measured depths and values
- Parameters
mds – a list of measured depths, one per sample
values – a list of values, one per sample
- Raises
PythonToolException – if the log is readonly
ValueError – if the measured depths and values are of difference lengths
- property comments#
The comments on the PetrelObject.
- Returns
The comments on the PetrelObject as a string.
- Return type
string
- property crs_wkt#
The PROJCS well known text representation of the object CRS.
- Returns
PROJCS well known text representation of the CRS.
- Return type
string
- property discrete_codes: Dict[int, str]#
A dictionary of discrete codes and values
Changes to this dictionary will not be persisted or affect any Petrel objects.
Example:
mylog = petrellink.welllog['facies'] print(mylog.discrete_codes[1]) # outputs 'Fine sand'
- property droid: str#
The Petrel Droid (object id or guid) for the object
Returns the Petrel Droid or object id or guid for the object. If not available, will throw a PythonToolException.
This property is planned to be deprecated in favour of a similar but more general id schema in future releases.
- Returns
The Petrel Droid of the object
- Return type
str
- property global_well_log: cegalprizm.pythontool.welllog.DiscreteGlobalWellLog#
The global well log this log is an instance of
- Returns
the global well log for this log
- Return type
- property missing_value: int#
The value interpreted by Petrel as a ‘missing’ one
- property path: str#
The path of this object in Petrel. Neither the Petrel name nor the path is guaranteed to be unique.
- Returns
The path of the Petrel object
- Return type
str
- property petrel_name: str#
Returns the name of this object in Petrel
- property readonly: bool#
The read-only status of this object
- Returns
True if the object is read-only
- Return type
bool
- property samples: cegalprizm.pythontool.welllog.LogSamples#
Gets or sets the log samples in the form of a
cegalprizm.pythontool.LogSamples
object- Raises
PythonToolException – if the log is readonly
ValueError – if the supplied value is not a cegalprizm.pythontool.LogSamples object
- property template: str#
Returns the Petrel template for the object as a string. If no template available, will return an empty string.
- property unit_symbol: None#
The symbol for the unit which the values are measured in
- Returns
The symbol for the unit, or None if no unit is used
- Return type
string
