Description: Faults: Inferred through poor seismic data and/or transcurrent fault zones - thrust zones poorly imaged on seismic; interpretation is questionable; fault intercepts remain largely unknown.
Time contour maps: Likely to be more than one seismic loop in error; correlation is either:
-pushed through seismic noise (based on plausible extrapolation or required for depth conversion purposes, etc.)
-not trusted, correlated events could be seismic artefacts and/or be severely distorted by migration effects.
Depth contour maps: poorer than 5 % precision achieved.
