Multiparameter full-waveform inversion: Marine and land examples

Autor: Alexandre Stopin, Harry Rynja, Ken Matson, René-Édouard Plessix, P. Milcik, S. Abri

Publikováno v: The Leading Edge. 32:1030-1038

Seismic full-waveform inversion (FWI), as proposed by Lailly and Tarantola in the 1980s (Lailly, 1983, Tarantola, 1987), consists of minimizing the misfit between observed and computed data. This data fitting approach is attractive because, theoretic

Acoustic and anisotropic multi-parameter seismic full waveform inversion case studies

Autor: P. Milcik, Alexandre Stopin, René-Édouard Plessix, Ken Matson

Publikováno v: SEG Technical Program Expanded Abstracts 2014.

Multi-parameter seismic full waveform inversion (FWI) is crucial to obtain reliable images of the subsurface. For cost efficiency, we often only carry out an anisotropic acoustic FWI while the data are elastic. In this way, we invert for two acoustic

Full Waveform Inversion with a Pseudotime Approach

Autor: Henning Kuehl, P. Milcik, Ken Matson, René-Édouard Plessix, C. Corcoran

Publikováno v: Proceedings.

Formulating full waveform inversion with earth models parameterized in vertical time can reduce, without removing it, the non-linearity of the inverse problem when hard contrasts are present in the initial models. The change of coordinates between th

Advances in onshore imaging

Autor: E. van Dedem, P. Milcik, M. van de Rijzen, H. Rynja, J. W. de Maag

Publikováno v: 72nd EAGE Conference and Exhibition - Workshops and Fieldtrips.

Onshore data typically poses additional challenges for processing and imaging in comparison with offshore data. Here we can think of limited access for acquisition, more variation in source and receiver coupling, more severe random noise conditions,

Least Squares Migration Applied to Improve Top Salt Definition in Broek Salt Diapir

Autor: P. Milcik, A. Hamood, B. Salomons, V. S. L. Goh, H. J. J. Rynja

Publikováno v: 71st EAGE Conference and Exhibition incorporating SPE EUROPEC 2009.

This project supports the drilling of an exploration well in the Broek structure situated in the north of the Netherlands (Figure 1) below a saltdome (Figure 2). For a proper assessment of the volumetric GIIP and compartmentalisation of the Broek pro
