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 ...

DALLAS–The great land grab in the Midland Basin has resulted in an exponential increase in acreage prices, with buyers paying up to $60,000 an acre in some cases. In this competitive environment, oil and gas companies–particularly smaller independents–are starting to look for prospective areas ...

Complex overburdens often distort reservoir images in terms of structural positioning, stratigraphic resolution, and amplitude fidelity. One prime example of a complex overburden is in the deepwater Gulf of Mexico, where thick and irregular layers of remobilized (i.e., allochthonous) salt are situated above prospective ...

This study is based on work performed on horizontal wells in the Cleveland Sandstone Formation. Previous work describes the technique of using automated, quantitative mineralogy (RoqScan) to analyse drill cuttings and derive rock property and elastic pseudo-logs to customize completion designs. We expand on ...

In this paper we present a new source-over-cable marine seismic acquisition technique that initially was developed to meet imaging challenges of the Loppa High in the Norwegian Barents Sea. Two seismic vessels operate in tandem; one streamer vessel towing a spread of deep, densely ...
