... Imaging of a pre-Messinian target in the Eastern Mediterranean Sea remains a challenging task. Recent gas discoveries, in the Eastern Mediterranean Sea, have increased interest in enhanced imaging beneath Messinian salt layers. To adequately image the pre-Messinian, various challenges need...

... of accretionary wedges are still subject of geological and geophysical interpretation. Given that subduction zones are generally located offshore, approaches from the field of marine geophysical imaging - in particular seismic acquisition and processing techniques- are the methods of choice to investigate...

... Conventional seismic processing and imaging workflows employ a range of techniques such as deghosting, designature, and demultiple to attenuate parts of the wavefield that would otherwise degrade the final image due to the single scattering assumption used in common imaging algorithms...

... Transition zone seismic data are intrinsically complex and can combine, at minimum, the complexity of marine, transition, and land seismic data. This paper presents the imaging results of a highly complex transition zone dataset. It is the industry’s first highly heterogeneous survey in terms...

The results have been correlated with an image log to confirm the nature and fill of the seismic lineaments. Understanding the variation in length and intensity of those events is critical to understanding...

... The ultimate challenge for shear-waves is to deliver amplitudes in depth and imaging reliability of P-waves, for estimation of reservoir quality, geomechanical parameters for well completion, and 3D/4D fluid-pressure characterization. Coherent converted P- to S-wave (PS-wave) depth imaging...

However, mobile marine vibrators introduce a unique set of processing and imaging challenges for ocean-bottom acquisition, such as the Doppler effect and the time-dependent source-receiver offsets, which are not features of conventional marine acquisition. Standard seismic data processing...

... The northern extent of the Green Canyon Protraction Area in the Gulf of Mexico has seen multiple decades of exploration interest. Until recently, given its complex salt tectonic history, the area’s subsalt structural framework has proved difficult to image, with the existence of the framework...
