the subsurface stack
Together, the open source Python packages and libraries on this page represent the Software Underground stack — the tools that enable us to work on the digital subsurface. Each has its own maintainers and community, but the Software Underground forms one of the bridges between them.

welly + striplog
Sister projects for handling wells, well logs, and sedimentary logs. Licence: Apache 2. Contact: Matt Hall.
bruges
The bag of really useful geophysical equations and stuff. Licence: Apache 2. Contact: Matt Hall.
segysak
