pywellcad is a Python library that provides an interface to ALT's WellCAD software using the automation module.

Currently, the library is in beta, and only exposes a thin wrapper around the COM API. As well as this COM API, we are working on a brand new, more Pythonic interface. Contributions and suggestions for the new interface are very welcome - take a look at the section below on Contributing.

• Python 3.6+
• WellCAD v5.5+ with a valid license for the Automation Module

Note: it is possible that the library will at least partially work with older Python and WellCAD versions, but these older versions are not supported.

In the future, pywellcad will be bundled along with WellCAD and a built in Python distribution. For now, you can install it manually in your own Python environment using pip:

pip install pywellcad

To ensure the WellCAD COM server is registered and can be used by pywellcad, please make sure that you have run WellCAD from an administrator user account at least once.

The COM interface is entirely available under the module wellcad.com. Importing this and instantiating an Application is the entrypoint to further functionality.

import wellcad.com

app = wellcad.com.Application()
sample_file_path = r"C:\Program Files\Advanced Logic Technology\WellCAD\Samples\Classic Sample.wcl"
borehole = app.open_borehole(sample_file_path)
gr_log = borehole.get_log("GR")
gr_log.file_export(r"C:\Temp", "sample_gr", "csv")

If you have problems or suggestions, please feel free to open an issue here on GitHub. Pull requests are welcome. For major changes, please open an issue first to discuss what you would like to change.

Please note, initial development of this library was done using a self-hosted Git platform (Gitea), so you may not have access to older issues/PRs.
