Political instability at many points of the world ... rising gasoline prices ... limited natural gas and oil reserves. These are just a few of the challenges facing the oil and gas industry as it...

The theme of the 2003 EAGE/SEG imaging workshop concerned the contrast between different philosophies of ‘model building’: whether an explicit, user determined model should be imposed throughout the...

Recent initiatives in the North Sea and UKCS such as the introduction of the ‘Fallow Field’ initiative and offering of ‘Promote’ licenses have started to generate activity by attracting new entrants...

Wave equation (or wave field extrapolation) techniques have been used in industry for the past few years, with the purpose to improve the accuracy of 3D depth imaging over the conventional Kirchhoff...

The deep offshore of the Gulf of Guinea is a major challenge to seismic processing and imaging techniques, due to the complexity of the salt body structures (figure 1). Even though Kirchhoff prestack...

In recent years we have seen processing and imaging algorithms re-written to handle anisotropic effects. The most common type of anisotropy that one deals with in seismic data is polar anisotropy...

Here we review several of the model building techniques introduced over the past decade or so, with emphasis on the assumptions and limitations of each technique. Model building techniques are...

It is sometimes remarked that pre-stack Kirchhoff depth migrated images have a lower frequency content than their time-domain counterparts. Various factors that influence frequency content during...

4D (also known as time-lapse or repeat) seismic has in the past few years emerged as a significant technique for monitoring fluid movement within reservoirs. In recent years, an improved...

The convergence of advanced computing technologies and innovative algorithm designs has made it possible to provide 3D Wave Equation depth migration methods to many explorationists. It is well known...
