Using the compression technique described by Donoho et al. we performed a field test of this technology by transmitting highly compressed seismic data from a multi-streamer ship to a land-based processing center in nearly real time. Using the M/V CGG Mistral, which acquired a 3D dataset over the Ninian field in the North Sea during the summer of 1995, and Ku band (14 GHz) satellite channels, we established the feasibility for sending both the traces and navigation data directly into the seismic processing system. While for the test, only a subset of the whole survey was sent to shore, the test was designed to demonstrate both technically and economically the feasibility of sending an entire 3D dataset on a day-to-day basis. The received data were decompressed and processed in parallel with the original data recorded on shipboard tape, to determine the effects of the compression-induced noise at the stack and migration stages will be shown.
