Conventional migration tools have been implemented by the application of adjoint operators. Under simple circumstances this approach provides satisfactory results. In situations where the overburden...

Wide azimuth (WAZ) has been established as an indispensable seismic acquisition and processing methodology for exploration and development objectives. This is especially relevant in the Gulf of...

In some of the newly explored areas around the world, 3D seismic surveys may not be available. Assessment of the exploration potential and in some cases, even a critical well-drilling decision is...

The frequency content and the temporal resolution of marine seismic data acquired using conventional constant-depth streamer is affected by the interference from the reflections at the sea surface in...

Seismic exploration of the Norwegian Barents Sea began over thirty years ago, but the acquisition of 3-D surveys have only commenced in recent years. The design of these surveys is based on the...

Broadband seismic data are becoming increasingly common, with many different methods of producing a broader range of frequencies. Accurately recorded broadband frequencies are of particular use for...

The study addresses the hydrocarbon prospectivity of offshore Gabon with a particular focus on the South Gabon Basin based on detailed 3D PGS/DGH MegaSurvey seismic and well data interpretation. It...

PGS has recently completed deployment of the worlds first, and to this date only, full-solution deep-water PRM project in the Jubarte field in Brazil for Petrobras. The project includes a fully...

In October 2012 the Alvheim-Boa Field was surveyed as part of a North Sea acquisition campaign with the newly developed Towed Streamer EM System to provide resistivity estimates over a number of...
