Well Data Show locates the nearest well log sample to the position of the current seismic gather and reports the corresponding time (or depth) value and lateral distance from the gather to that well log point. This module is used to cross-reference well log curve data with seismic gathers during interpretation, allowing the user to quickly check which well log sample is closest to a given gather location.
The module searches across all curves in the connected LAS curve dataset and finds the single closest point (by horizontal X-Y distance) to the gather's common exploration point. It then outputs that point's Z value (time or depth) and the computed distance.
The seismic gather whose spatial position is used as the reference point for finding the nearest well log sample. The gather must have a valid common exploration point (X-Y coordinates) derived from its trace headers.
The well log curve data, typically loaded by the Well data exchange module from a LAS file. Each curve is represented as a set of points with X (curve value), Y (lateral coordinate), and Z (depth or time) components. All curves are searched to find the point geographically nearest to the input gather.
This module has no user-adjustable parameters. The nearest point search is performed automatically using the gather position and the connected LAS curve data.
The Z value (time or depth) of the nearest well log point found in the LAS curves, reported in the units of the input well log data.
The horizontal (X-Y plane) distance between the input gather position and the nearest well log point, in metres. A small distance indicates the gather is close to the well location.
