Seismic art sketches
Data art from seismic amplitude. Every example here is synthetic, generated by
seismic_art from a convolutional model (no real survey). Amplitudes are relative;
each figure states its domain and polarity. Served from web/.
A · Seismic rings
A circle cut from the volume and wrapped into polar form: angle along the circle, radius = time. Callouts mark the clearest layers and their brightest trace.
B · Waveform cities
Waveforms along a thin-bed wedge, grouped by a self-organising map.
C · Growth rings per horizon
An attribute round each site on five horizons, oldest outermost.
D · Flow over a surface
Streamlines of steepest descent on a picked horizon, coloured by amplitude. Callouts mark structural highs, lows and saddles.
E · Trace shells
Each trace drawn from its analytic signal: angle = instantaneous phase (one turn per cycle), radius = time, width = envelope, colour = instantaneous frequency. One rule, one shell per trace.
F · Fault constellations
Picks whose waveform differs from their neighbours' become stars, joined into constellations; checked against the built-in fault.
G · One thread
Every trace of the survey, in file order, wound along one spiral; across the thread a thin slab of time, colour = amplitude.
I · Double exposure
Two vintages of one survey on the same ring, in two inks: where the earth did not change they fuse to one tone, where the monitor differs they separate into fringes. Also as a slow cross-fade, the ring breathing.
J · Unwinding shells
Each trace drawn twice from its two vintages: the base's phase in grey, the monitor's in colour on the same radius. Where the monitor lags the spirals twist apart.
K · Engraving of what changed
A section drawn as fine wiggles, with everything the base also has erased: the grain of repeatability above, the strokes of change below.
Volve, real data
The same four sketches on the Volve ST10010 stack and its interpreted surfaces (Equinor ASA and partners, Volve Terms and Conditions). Cities become the named surfaces.
