Arbitrary lines - contains all seismic arbitrary lines created in g-Space
Right mouse button on the icon allows to:
•Add arbitrary line
•Clear arbitrary lines
•Add folder
An arbitrary line is a user-drawn path through a 3D seismic cube that extracts seismic traces along any geometry — not only the native in-line / cross-line grid. Use it to follow a geological feature, connect key wells on a single panel, or build a custom cross-section through a field. The path is defined interactively in a 3D or map view and the resulting gathers appear in a dedicated 2D view.
1.Open a 3D view or Location map showing the target cube.
2.Enable arbitrary-line creation from the view toolbar and click the cube to place successive anchor points (corners).
3.Double-click or press Enter to finish the path. g-Space builds the bin sequence along the polyline and extracts traces for every domain available on the cube (time, depth, offset …).
4.Manage existing lines (rename / delete / activate) from the Data manager under the Arbitrary lines node.
•Step — distance between consecutive bins along the line. Default 25 m.
•Max Distance — maximum lateral distance from the polyline beyond which 3D traces are ignored when interpolating. Default 200 m.
•Straighten on 3D view — when enabled, the line is rendered as a straight plane inside the 3D view for easier inspection.
•Display extracted gathers in the dedicated 2D view and pick horizons / faults on them as on any seismic section.
•Inspect the nearest wells and nearest 2D lines to each corner — g-Space keeps per-corner associations for quick context switching.
•Convert the extracted path into a standalone 2D line or export it to SEG-Y for sharing.
