Imaging Beneath a Gas Cloud in the North Sea without Conventional Tomography
Autor: Michael Warner, Are Osen, Joachim Mispel, T. Nangoo, Lluís Guasch, F.A. Maaø, C. Ravaut
Publikováno v: Proceedings.
To reduce sensitivity of full-waveform inversion to cycle skipping, new objective functions have been introduced in the last couple of years. We here investigate the capability of adaptive waveform inversion (AWI) based on Wiener coefficients which w

Attenuation of free-surface multiples by up/down deconvolution for marine towed-streamer data
Autor: Ed Kragh, Ian Moore, Joachim Mispel, Mark Thompson, Clement Kostov, Mariusz Majdański
Publikováno v: GEOPHYSICS. 76:V129-V138
Free-surface-related multiples in marine seismic data are commonly attenuated using adaptive subtraction of the predicted multiple energy. An alternative method, based on deconvolution of the upgoing wavefield by the downgoing wavefield, was previous

Improved applicability of ray tracing in seismic acquisition, imaging, and interpretation
Autor: Einar Iversen, Joachim Mispel, Isabelle Lecomte, Åsmund Drottning, Håvar Gjøystdal, Tina Kaschwich
Publikováno v: GEOPHYSICS. 72:SM261-SM271
Ray-based seismic modeling methods can be applied at various stages of the exploration and production process. The standard ray method has several advantages, e.g., computational efficiency and the possibility of simulating propagation of elementary

3D Full-waveform inversion at Mariner — a shallow North Sea reservoir
Autor: Marianne Houbiers, Christoph Koeninger, Dmitry Nikolenko, Edward Wiarda, Denes Vigh, Mark Thompson, Joachim Mispel
Publikováno v: International Geophysical Conference and Oil & Gas Exhibition, Istanbul, Turkey, 17-19 September 2012.
We applied isotropic acoustic 3D full-waveform inversion (FWI) to OBC data from the Mariner field, a shallow heavy-oil field in the North Sea. This resulted in a multiphase workflow that can be adapted to imaging challenges in similar geological sett

Full azimuth seismic modeling in the Norwegian Sea
Autor: Edward Hager, Joachim Mispel, Marianne Houbiers, Buckingham Gate, Børge Arntsen, Gordon Brown, David Hill
Publikováno v: SEG Technical Program Expanded Abstracts 2008.
SUMMARY One of the fields in the Norwegian Sea has been imaged several times over the past decades, both with conventiona l narrow azimuth seismic surveys as well as with ocean bottom seismic. The extensively faulted structure of the field and the po
