1. PGS Reservoir, Oslo (Norway)

Marine four-component (4C) acquisition has been gaining significant worldwide interest, especially in the North Sea where several 4C surveys have been acquired over the last 2 years. Still in its early days, 4C--or, more generally, multicomponent--marine seismic has already been identified as an important tool for both exploitation and exploration. PGS Reservoir is one of the pioneers in marine 4C acquisition. In a large number of test surveys and several commercial surveys, its Dragged Array technique has reduced acquisition costs significant without compromising quality of the data. The paper discusses marine S-wave surveys, 4C data acquisition, why S-waves are used, reservoir changes, complementary images, special processing, and future developments.
