PetroPy
=======

A python petrophysics package allowing scientific python computing
of conventional and unconventional formation evaluation. Reads las
files using `lasio <https://github.com/kinverarity1/lasio>`__. Includes
a petrophysical workflow and a log viewer based on XML templates.

Requirements
------------

-  `lasio <https://github.com/kinverarity1/lasio>`__
-  `numpy <http://www.numpy.org>`__
-  `scipy <https://www.scipy.org>`__
-  `pandas <http://pandas.pydata.org>`__
-  `matplotlib <http://matplotlib.org>`__
-  `scikit-learn <http://scikit-learn.org/stable/>`__

Installation
------------

Install PetroPy through pip via the command line

.. code-block:: bash

  pip install petropy

To read in an las file, pass the file reference:

.. code-block:: python

  import petropy as ptr
  file_path = r'path/to/well.las'
  log = ptr.Log(file_path)

Documentation
-------------

View the `online documentation`_ for classes and methods.

Las File Processing
-------------------

To understanding using petropy in a petrophysical workflow for las file
processings, see the `example page`_.

Petrophysical Model Quick Look
------------------------------

.. code-block:: python

  >>> # import petropy and print raw curves
  >>> import petropy as ptr
  >>> log = ptr.log_data('WFMP')
  >>> print(log.curves)
