The Gippsland Basin in South-Eastern Australia is located approximately 200 km east of the city of Melbourne, and remains one of Australia's most prolific oil and gaThe major fields were discovered in the early 1960’s, using images from a coarse 20-km (12 mile) grid ...

Here we use a multi-client magnetic airborne survey to interpret and estimate the magnetic basement relief of the Jequitinhonha Basin. Satellite Gravity, seismic lines and well logs are integrated in the interpretation. Exudation points are also analyzed constructing a relationship between structural features and ...

In this work we propose to revisit some of the main steps of a seismic reservoir characterization workflow, using a MCNV Campos Basin broadband seismic dataset. The objective is to illustrate the differences with conventional seismic data, identify potential pitfalls and suggest best practices ...

Despite continuous improvements in seismic acquisition and processing technology, imaging under the salt remains very challenging, specifically because of the difficulty to update the complex salt geometries and the velocity under them. Synthetic studies show that when certain conditions are met, full waveform inversion ...

Demonstrate the value of least-squares migration on various complex geology around the world. It includes real data examples published by various SI teams such as least-squares Kirchhoff for tow-streamer/OBS 4D, LS-RTM for subsalt imaging, least-square Q-PSDM on Northsea & Austrialia.

TopSeis is a radically new solution for seismic acquisition and imaging, developed through collaboration between an oil company and the service sector.

A new method is outlined that allows you to use isotropic seismic modeling and inversion technology in an anisotropic setting. The method is based on the mapping of the isotropic elastic parameters into effective elastic parameters, appropriate for the expected type of anisotropy. This ...

A recent 3D Broadseis survey was performed in the southern offshore area of Gabon, showing a wealth of detailed information in the seismic data. Understanding how these structures relate to the tectonic evolution of this basin requires the integration of the concurrently acquired gravity ...

We propose a data-driven interferometry technique to remove low frequency aliased and non-conical surface waves in cross-spread domain. Despite insufficient sampling of the constructive regions in the cross-spread domain, the proposed approach has been designed for effectively handling any kind of 3D sparse geometry ...
