Summary:
Seismic acquisition for Petroleum Exploration in Artic regions is usually restricted to the winter season. Conventional seismic methods require that the survey area and acquisition parameters are constrained to match the narrow time frame. The quality of seismic image and reliability of predicted amplitude anomalies of shallow targets is restricted by the smaller trace contribution at shorter times in the seismic gathers. Exploration of shallow targets requires very densely sampled surveys by reducing line spacings and point intervals. Our recent experience in Kuukpik 3D Alaska (USA) demonstrates that ultra-high source density supported by unconstrained simultaneous sources overcomes the limitations of conventional seismic acquisition in Artic regions.
