Reverse-time migration (RTM) provides superior images in areas where there are steep salt flanks or other complex geologic structures. However, the high cost of running RTM with regard to memory...

We present a case study of anisotropic model building and the resulting accuracy of event placement and improved image quality. Approximately 660 OCS blocks of the MC Revival survey located in...

Subsalt wave-equation based migration (WEM) scan is an effective way for subsalt velocity updating, and has become an industry standard practice; however, the cost of generating migration scan is...

Much of the thinking behind conventional geophysical processing assumes that we wanted to image energy that propagates down from the surface of the earth, scatters from a reflector or diffractor, and...

Seismic imaging of hydrocarbon accumulations below salt is a formidable challenge because complexly shaped salt bodies severely distort wavefronts or scatter seismic energy. We have highlighted some...

Here we present the synthesis of available geological and geophysical data in order to discuss the presentday structure, geological history and hydrocarbon potential of northeastern Black Sea region,...

The onshore and offshore portions of the Eastern Mediterranean basin (Fig. 1) have proven to be a prolific hydrocarbon producing area. As of December 2006, oil reserves are 15 billion bbl and gas...

The industry is acquiring increasing numbers of wide azimuth surveys. In soft rock settings, such as the Gulf of Mexico, the objective is usually to improve illumination and imaging of obscured or...

During the Mesozoic and Early Cenozoic, and before sea floor spreading occurred in the North Atlantic Ocean, the North American and Eurasian continents were closely juxtaposed (Fig. 1). In...

Imaging in deep water environments poses a specific set of challenges, both in the data preconditioning and the velocity model building. These challenges include scattered complex 3D multiples,...
