Build status:

Segpy is alpha software but is usable in its current form. That said you should expect minor breaking API changes between now and official release of a Segpy 2.

The SEG Y file format is one of several standards developed by the Society of Exploration Geophysicists for storing geophysical seismic data. It is an open standard, and is controlled by the SEG Technical Standards Committee, a non-profit organization.

This project aims to implement an open SEG Y module in Python for transporting seismic data between SEG Y files and Python data structures in pure Python.

The easiest way to contribute is to use Segpy submit reports for defects or any other issues you come across. Please see CONTRIBUTING.rst for more details.

Segpy 2.0 is a complete re-imagining of a SEG Y reader in Python and represents a complete break from any and all older versions of Segpy. No attempt has been made to maintain API compatibility with earlier versions of Segpy and no code is shared across versions. Although earlier versions of Segpy were open source, they were never 'released' as such. Earlier versions of Segpy are deprecated and completely unsupported.
