Time-lapse seismic processing in carbonate fields having complex geology and in difficult seismic contexts requires highly specialized teams for success. Our field case has a flat structure, a poorly-imaged but highly reflective sea bottom and is covered by towed-streamer data in about 60m of ...

2D deconvolution is an attractive approach for short period multiple prediction as it does not require direct recording of the multiple generator and can model multiples relating to more than one multiple generator at a time. One drawback, however, relates to an inherent over ...

Make a technical workflow including rockphysics, post-stack gestatistical inversion, seismic forward research and coal constrained pre-stack geostatistical inversion for the fine reservoir predictiong under coal interbedded. This work flow achieved huge success in the new development wells drilling.

A subsurface volume that can be reliably interpreted in terms of geologically-relevant attributes is a reasonable objective for products from depth inversion workflows. Commonly the field geophysics data available are inherently non-unique and deficient (noise, aliasing, etc.), so an implementation of some type of ...

Standard reflection-based model building for land applications is challenging due to reduced data quality, near-surface heterogeneities, and the low-fold of reflection data at shallow depths. Broadband and large offset data acquisitions have been developed with the aim of investigating full waveform inversion (FWI) as ...

Over the recent years, numerous case studies have highlighted the strong link between the geophysical value of seismic acquisition and the maximization of two metrics: trace density (expressed as the number of source-receiver pairs per square kilometers) and frequency bandwidth (expressed in octaves). Here ...

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.
