Broadband Seismic Methods for Towed-streamer Acquisition

Three-dimensional inversion of towed streamer electromagnetic data

A towed streamer electromagnetic system capable of simultaneous seismic and electromagnetic data acquisition has recently been developed and tested in the North Sea. We introduce a 3D inversion methodology for towed streamer electromagnetic data that includes a moving sensitivity domain. Our implementation is based on the 3D integral equation method for computing responses and Fréchet derivativ...

Optimal marine streamer acquisition with High-Density 3D

Historically though, 3D marine streamer acquisition has been forced to compromise spatial sampling in the name of efficiency and cost. This compromise translates to noise and degraded resolution when processing the data. A significant component of the seismic “noise” contaminating 3D images actually arises during processing, as an unfortunate and inescapable artifact from poor 3D spatial sampli...

3D inversion of towed streamer EM data: a model study of the Harding field with comparison to CSEM

Michael S. Zhdanov, Chris Anderson, Masashi Endo, Leif H. Cox, Martin Čuma, Glenn A. Wilson, Noel Black and Alexander V. Gribenko provide an early study of the challenges involved in validating offshore electromagnetic (EM) data acquired using a towed streamer receiver (currently under development) and compare the results with existing seabed-based marine controlled source electromagnetic (CSEM...
