A case history in West Texas, in the Permian Basin, of a non-exclusive seismic imaging project spanning acquisition, processing and reservoir interpretation. Located in Howard and Glasscock counties, the Hobo non-exclusive seismic survey aims at imaging and quantitatively interpreting the Spraberry and Wolfcamp formations.

Although good for time-lapse monitoring, ocean-bottom surveys often miss the first time-step of initial fluid production. To capture this it is necessary to co-process ocean-bottom data with the exploration dataset, usually towed streamer. Our North Sea study has significant 4D noise produced by un-cancelled ...

The purpose of this abstract is to highlight how some of the inconsistencies relating to environmental and acquisition differences are and dealt with in the context of fast delivery Snorre PRM data. The topics summarised are those which have been especially important to the ...

Abstract focusses on the LiveLand ESA IAP project and summarises how earth observation, weather forecast and GNSS can assist with the challenges transport operators across Scotland experience in relation to landslides and ground deformation along transport routes.

Structural information in seismic images is critical for reservoir delineation, reserve estimation and well planning, but is also uncertain by nature. A cause for this is uncertainty in migration model estimated by tomography that straightforwardly affects position of migrated events, both laterally and vertically ...

This paper focusses on improving the seismic image on a dataset from offshore Trinidad; Tobago by using full-waveform inversion (FWI) to refine the shallow velocities and also describes geological information that can be inferred directly from the resulting velocity model. In the first half ...

Ocean Bottom Cable (OBC) acquisition has become the new trend in Bohai area with the benefit of operational flexibility, better illumination, better multiple elimination and better S/N for the targets at middle to deep depth. However, the presence of orthorhombic anisotropy causes severe challenges ...

This article reviews the status of hydrocarbon exploration and level of geological understanding in the Durban and Zululand Basins offshore South Africa and it provides clues and new ideas from seismic interpretation and observations of the latest CGG multi-client 2D shot in the area ...

The Amplitude Versus Azimuthal AVAZ analysis has proved to be an important tool for characterizing fracture distributions and orientations of hydrocarbon reservoirs. This paper is aiming at the application of this tool for characterizing the fractures in Bahrain field reservoirs. Better understanding of faults ...
