Conventional marine acquisition uses a streamer towed at a constant depth. The resulting receiver ghost notch gives the maximum recoverable frequency. To push this limit, the streamer must be towed at a quite shallow depth, but this compromises the l

Variable-depth streamer acquisition is a broadband streamer acquisition technique where the depth profile of the streamer is optimized in order to ensure receiver ghost diversity, which in turn allows the deconvolution of the residual ghost at the im

In recent years, wave-equation migration has greatly enhanced imaging in complex velocity models. However, velocity model building is still dependent on ray-theory approximations. We propose a full wave-equation methodology for velocity model buildin

Contrary to conventional seismic that focuses on a narrow band in middle frequencies, broadband seismic aims at acquiring information within the whole bandwidth emitted by the source. A good knowledge of the source signature is thus of paramount impo

Summary The computation of velocity by tomography using Residual Move-Out (RMO) curves is widely used in the industry. The semblance-based, automatic dense picking of RMO has proved to be a very efficient technique for conventional data. However, in

Variable-depth streamer acquisition is becoming a key marine solution for providing wide bandwidth seismic data. Varying the receiver depths creates wide receiver ghost diversity which allows a spectacular increase in the recorded frequency bandwidth
