Publikováno v: International Petroleum Technology Conference.
Abstract We present a case study from the North West Shelf of Australia where the complexity of the overburden consists of several thin multi-level channel systems filled with a combination of anomalously high or low velocity sediments. Not accountin

Recent Advances in Data Selection and Data Conditioning for FWI
Autor: Hongyan Li, Denes Vigh, Alex Cooke, Timothy Bunting, Daniela Amazonas, Stephen Alwon, Stephen Klug
Publikováno v: 13th International Congress of the Brazilian Geophysical Society & EXPOGEF, Rio de Janeiro, Brazil, 26–29 August 2013.
In the latest years FWI started to be used to improve the velocity models in a commercial way. But it is still an expensive process. In this paper we show the application of batch sampling as a tool to decrease the FWI run time. Moreover, we present

Publikováno v: SEG Technical Program Expanded Abstracts 2013.
Summary A workflow for integrating full waveform inversion (FWI) with reflection tomography has been refined using narrow azimuth towed streamer (NATS) 3D seismic data from the North West Shelf (NWS) of Australia. We show that FWI using relatively sh

Publikováno v: SEG Technical Program Expanded Abstracts 2013.
Summary Advances in acquisition and processing technology help overcome imaging challenges in complex structural settings. The widespread adoption of wide-azimuth (WAZ) and the move towards full-azimuth (FAZ) acquisition geometries, both combined wit
