“…N-S. As will be shown later, these Tollefsen et al 1994). features are mostly related to seismic noise. Similar effects have also been recognized by Hoetz & Watters (1992). Due to the overprinting effect of the noise, N-trending faults on the Gullfaks Field may be under-represented with respect to more E-trending structures.…”

“…In theory, however, side-scattered noise signals should in 3D seismic be migrated to their proper position. Hoetz & Watters (1992) related the (curvi-)linear features observed on a dip map to reflection discontinuities resulting from migration and/or stack errors in seismic processing. It is also possible that the linear dipping events on the stacked sections result from 'streamer noise' caused by pull and drag on the streamer.…”

“…The technique of artificially illuminating surfaces has been used for aeromagnetic data for more than a decade (Tucker et al 1985;Kowalik & Glenn 1987) but has only recently been incorporated into seismic interpretation (Hoetz & Watters 1992;Dorn et al 1995;Eggink et al 1996).…”

Seismic attribute maps provide a useful tool in interpreting faults, particularly those close to or below seismic resolution. Dip, relief, azimuth and amplitude maps are most useful. Optimal use of such maps requires careful filtering and appropriate use of colours and light sources. One of the challenges is to distinguish between anomalies related to real geological features and to seismic noise -both of which may occur as linear or curvi-linear, continuous features on the attribute maps. This challenge must be solved by use of independent data. In the North Sea Gullfaks Field, a family of (curvi-)linear features on the attribute maps are subparallel to contour lines on time maps. Core data, dipmeter data, stratigraphic log correlation and forward modelling show that these features are related to seismic noise rather than real faults.
