Why Norwegian seismic is still running in Anders Farestveit’s direction
By A. McBarnetNo one who knows him will be in the least surprised that Anders Farestveit is far from retired and is as busy as ever. Now, in his late 60s, his day job is chairman and inspiration behind Wavefield-Inseis, the rapidly emerging Norwegian marine geophysical services company. Andrew McBarnet has been speaking to the man often referred to as the father of Norway’s seismic industry.

How multi-azimuth and wide-azimuth seismic compare
By A. LongAndrew Long of Petroleum Geo-Services (PGS) takes a look at the claims made for multiand wide-azimuth surveys and comes up with some surprising conclusions.

Reduction of acquisition time sharing in the North Sea by Seismic Interference attenuation
Authors T. Manning, J. H. Kommedal, R.J. Wombell, T. Noss and T. PokrovskaiaTed Manning, BP UK, Jan H. Kommendal, BP Norway, and Richard Wombell, Tony Noss, and Tamara Pokrovskaia (Veritas DGC, UK) describe how the issue of Seismic Interference between different survey companies in the same vicinity can be resolved.

From narrow-azimuth to wide- and rich-azimuth acquisition in the Gulf of Mexico
Authors N. Moldoveanu and M.S. EganNick Moldoveanu and Mark Egan, Schlumberger WesternGeco, Houston report on the experience of wide- and rich-azimuth towed streamer seismic acquisition to date and the challenges which still have to resolved.

Filling the gap: integrating nodes and streamer data for geophysical monitoring
Authors E. Ceragioli, A. Kabbej, A. Gonzalez Carballo and D. MarinE. Ceragioli, A. Kabbej, and A. Gonzalez Carballo of Total, and D. Marin of CGG, discuss how sparse distribution of seabed node receivers can complement conventional marine seismic streamer technology in the surveying of sensitive or obstructed targets with an example from an ultra deep water oil and gas field project.

Seismic investigation of the Great Sumatra-Andaman earthquake
Some of the first seismic survey research* aimed at understanding the 2004 tsunami which caused so much devastation in SE Asia has been completed. This is the progress so far. The tsunami from the Great Sumatra earthquake of 26 December 2004 killed approximately 300,000 people in South East Asia and caused unaccountable loss of property. The main earthquake (Mw~9.2-9.3, pure thrust focal mechanism) was the biggest such event for the last 40 years and occurred along the Sumatran subduction zone. It was followed by hundreds of aftershocks and by an Mw=8.7 earthquake to the south on 28 March 2005.

Resolution and uncertainty in spectral decomposition
By M. HallOver the last five years or so, spectral decomposition has become a mainstream seismic interpretation process. Most often applied qualitatively, for seismic geomorphologic analysis (e.g., Marfurt and Kirlin, 2001), it is increasingly being applied quantitatively, to compute stratal thickness (as described by Partyka et al., 1999). It has also been applied to direct hydrocarbon detection (Castagna et al., 2003). Broadly speaking, we also apply the principles of spectral decomposition any time we extract a wavelet or look at a spectrum. To date, most of this work has been done with the windowed (‘short-time’) Fourier transform, but other ways of computing spectra are joining our collective toolbox: the S transform (Stockwell et al., 1996), wavelet transforms, and matching pursuit to name a few (e.g., Castagna and Sun, 2006).

Understanding stochastic inversion: part 2
By A.M. FrancisAshley Francis, managing director of UK consultancy Earthworks Environment & Resources, provides the second and final part of his tutorial on the theory of deterministic and stochastic inversion with some comparison of the pros and cons of the two methods. The first part appeared in the November issue of First Break.
