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.

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 ...

Recent discoveries in the Pil and Bue prospects, targeting Melke and Rogn Formation sandstones on the footwall of the Vingleia Fault complex, have rejuvenated interest in exploration around the Frøya High region. The wildcat well, 6406/12-3 S (Pil 1), with estimated resources of 8.8-21.1 ...

Porosity estimation using EMERGE for an onshore Abu Dhabi field. CGG processed the seismic and it was followed by seismic inversion. The P-impedance was further used in predicting the porosity. This porosity result very helpful to client to well planning and drilling to target ...

The characteristics of lithologic reservoirs, such as complex channels with distinctly lateral variations and variable thickness, make such reservoir features difficult to identify when using conventional geostatistical methods or applying seismic attribute methods. To decrease the uncertainty and improve the lateral distribution of the ...

Free-surface datum variations cause complications for hydrophone only receiver deghosting algorithms that assume a horizontal free-surface. We describe a multi-shot receiver deghosting approach that derives a tau-psht-prec model of ghost free data at mean free-surface datum. The model is derived so as to simultaneously ...

In this paper, we develop Dynamic-warping Full Waveform Inversion (D-FWI) to address cycle skipping problem which is a well-known challenging issue in conventional FWI. The dynamic warping technique is used to detect the travel time difference between the predicted and the observed wave fields ...
