git clone https://github.com/oilshit/las_converter
cd las_converter

Python environment setup is recommended for using this project repository. Type ./check-pyenv.sh (using Linux/Unix terminal console or WSL console) for validating Python environments. By default, Python virtualenv has not been set yet so that it will be return results as below.

'env' directory is not exist.
 you can install Python virtualenv (and also activate it) by
 virtualenv env; source env/bin/activate 

 install Python dependencies then by
 pip install -r requirements.txt

or you can create the environment variable manually by typing command below on Linux or MacOS (and also WSL console).

python -m venv venv
source venv/bin/activate

and also for Windows.

python -m venv venv
venv\Scripts\activate

In terminal, just type the yellow text given to proceed.

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 Google Colab console.

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