Can segyio handle 2D seismic data as well as 3D?

Yes, segyio can read unstructured 2D lines or unsorted seismic data by using the ignore_geometry flag.

How does segyio compare to ObsPy or segysak?

Segyio is the fastest choice for low-level SEG-Y I/O and 3D slices. ObsPy is better for general seismology (waveforms/events), while segysak is preferred for xarray integration.

What is the primary benefit of using segyio with Claude Code?

It allows Claude to generate precise, high-performance code for seismic data I/O, specifically handling the complex 3D indexing and header structures inherent in SEG-Y files.

Can I modify existing SEG-Y files in place?

Yes, this skill provides patterns for opening files in 'r+' mode to update specific traces or header values without rewriting the entire file.

数据科学与机器学习

Facilitates high-performance reading, writing, and manipulation of SEG-Y seismic data files for geophysical analysis.

The segyio skill enables Claude to efficiently handle SEG-Y seismic data, providing domain-specific guidance for accessing traces, headers, and 3D survey geometries. It leverages the fast C-based segyio library to allow for rapid inline and crossline slicing, header modification, and the creation of new SEG-Y files from NumPy arrays. This is an essential tool for geoscientists and data engineers who need to integrate seismic data into automated workflows, machine learning pipelines, or complex geophysical processing tasks.
