seisvis 0.1.3

Seismic data visualization and plotting utilities

SeisVis - Seismic Data Visualization Library

A simple and easy-to-use Python library for seismic data visualization, designed for geophysicists and seismic data analysts.

The motivation behind developing seisvis is to reduce repetitive plotting code during paper writing and to enable customized figure generation directly in Python. With SeisVis, users can create high-quality static plots in their preferred style without the need to open and manipulate data in heavy software platforms.

🌟 Features

• Easy to Use: Minimal API design - create professional seismic visualizations with just a few lines of code
• Lightweight Dependencies: Only requires matplotlib - no complex environment setup needed
• Full Dimensional Support: Supports 1D, 2D, and 3D seismic data visualization

🚀 Quick Start

Installation

pip install seisvis

Basic Usage

2D/3D Seismic Visualization with DataCube

This is just a demonstration; We strongly recommend checking out vis_demo.ipynb for more details.

from seisvis.datacube import DataCube
from seisvis import plot2d， plot3d

# Initialize DataCube
data_cube = DataCube()

# Add your data
data_cube.add_seismic("Seis1", seismic_data)
data_cube.add_property("Prop1", property_data)
data_cube.add_horizon("Top", top_horizon)
data_cube.add_horizon("Base", top_horizon)
data_cube.add_well("Well-1", well_data)
data_cube.add_well("Well-2", well_data)

# 2D Section Plotting
config2d = PlotConfig()
size = [il_start, il_end, xl_start, xl_end, t_end, t_start]
plotter2d = plot2d.Seis2DPlotter(data_cube, size, config2d)

# Configure display settings
show_seismic = {'type':'Seis1', 'cmap':'Grey_scales', 'clip':'robust', 'mask':False, 'bar':True}
show_properties = {'type':'Prop1', 'cmap':'AI', 'clip':'robust', 'mask':True, 'bar':False}
show_horizons = {'type':['Top', 'Base'], 'cmap':None, 'clip':None}
show_wells = {'type':['Well-1', 'Well-2'], 'cmap':'AI', 'clip':None, 'width':4}

# Plot inline section
plotter2d.plot_section(section_idx=639, section_type='inline',
                       show_seismic_type=show_seismic,
                       show_properties_type=show_properties,
                       show_horizons_type=show_horizons,
                       show_wells_type=show_wells)

# 3D Visualization
config3d = PlotConfig()
config3d.label_fontsize=14
config3d.tick_labelsize=14
plotter3d = plot3d.Seis3DPlotter(data_cube, size, config3d)
plotter3d.plot_slices(show_seismic_type=show_seismic,
                      show_wells_type=show_wells)

Example Outputs:

• 2D Inline Section with Horizons and Wells
  

• 2D Inline Section with Masked Properties and Wells
  

• 3D Seismic Slices with Well Overlay
  

📊 Main Components

1. 2D Plotting (plot2d)

• Inline and crossline section visualization
• Seismic amplitude and property overlay
• Horizon and well trajectory display

2. 3D Plotting (plot3d)

• 3D seismic volume slicing
• Well trajectory in 3D space
• Static 3D rendering (interactive features planned)

3. DataCube Management

• Unified data container for seismic projects
• Support for multiple seismic volumes
• Horizon and well data integration
• Easy data organization and access

🔧 Current Limitations

• 3D Visualization: Currently supports static 3D plots only
