| Abstract |
3D seismic data are routinely used in deep-water exploration areas for site investigation work as well as for basic production prospect evaluation, as this helps to reduce costs. This report presents the critical parameters that influence the suitability of 3D surveys for site investigation work. Published guidelines and industry practice suggest that where 3D surveys specifically target the seabed and near-seabed sections, a vertical resolution of 6m and finer are possible in water depths greater than 500m. This is comparable to a conventional site survey vertical resolution of 4-5m. However, 3D surveys where the seabed is not a target possess significantly lower vertical resolutions and are not fit as a substitute for site surveys. |
