General information

About the workshopWhen seismic receivers are located on land or on the ocean bot-tom, the recorded wavefield is complex, certainly more complex than that recorded with marine streamer within a homogenous water layer. However, this complexity also provides the opportu-nity to record more fully and to utilize this complex wavefield. It is on land or the ocean bottom where we can plant a large fixed spread of receivers, and densely record fuller azimuths us-ing high productivity simultaneous sourcing. By moving away from the ocean surface ghost, we can excite and record broad-band data better. There is a condition for using this richer data, namely the ability to handle the distortion and noise associated with the heterogeneous near surface, which vary significantly with azimuth. This workshop will focus on the new advances in land and ocean bottom equipment/acquisition design, processing, and reservoir characterization that result in unparalleled signal-to-noise quality for these challenging environments. Specific sub-topics for this 5-day workshop include noise, sources, receivers, productivity, low and high frequencies, survey designs, imag-ing, inversion and more.
