Wide Azimuth Towed Streamer: Applications for Exploration as Well as Development

Broadband Seismic Methods for Towed-streamer Acquisition

Narrow-azimuth migration of marine streamer data

I introduce a new migration method that overcomes the limitations of common-azimuth migration while retaining its computational efficiency for imaging marine streamer data. The method is based on source-receiver downward-continuation of the prestack data with a narrow range of cross-line offsets. To minimize the width of the cross-line offset range, while assuring that all the recorded events a...

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...

A Novel Conceptual Model for Accessing Distributed Data and Applications, as well as Devices

As data and services are increasingly distributed in the network, rather than stored in a fixed location, one can imagine a scenario in which the Personal Computer, intended as a static workstation, is really disappearing. In such a scenario, users’ interactions are going to be mediated by ad-hoc connected devices, whose specific functionalities enable people to interact with data and services ...
