Getting started

back to top

For the first time use, firstly import the external function by

# import las_converter
import las_converter

# get help
help(las_converter)

or

# import las_converter
from las_converter import WellLog

# get help
help(WellLog)

There is a file named las_testing.py used for testing purposes. There is also Jupyter Notebook file called using_las_converter_in_well_log_analysis.ipynb that also can be used in Jupyter console.

For testing the saved files in results folder, there is also Jupyter Notebook file using_csv_made_from_las_converter_for_well_log_analysis.ipynb.
