In this paper we present a new source-over-cable marine seismic acquisition technique that initially was developed to meet imaging challenges of the Loppa High in the Norwegian Barents Sea. Two seismic vessels operate in tandem; one streamer vessel towing a spread of deep, densely ...

We demonstrate a recently developed method for computing tomography model uncertainties and mapping them into the migrated domain. The method generates after the final tomography a series of equi-probable velocity model perturbations within a standard deviation confidence level. This allows computing standard deviation-like attributes ...

Self-published 12-page White Paper on the subject of National Data Repositories. Distributed at NDR conference in June 2017.

The detection and mapping of fractures in migrated poststack 3D seismic data depends on the resolution and signal-tonoise ratio of the data in the seismic volume. A discussion of resolution problems and the limits of resolution in post-stack 3D seismic data, and structurally-oriented post-stack ...

Seismic Interference (SI) has long been a problem for seismic data acquisition in congested areas such as the North Sea, but thanks to advances in processing algorithms and new cooperative management techniques developed in conjunction with Statoil and RIL, downtime or time sharing due ...

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 ...

We discuss a feasibility study to access the 11,500 well headers and 450,000 documents from the United Kingdom Continental Shelf (UKCS) that were released by Common Data Access Limited. A cost-effective solution based on emerging machine learning technology “taught” and guided by data-management experts ...

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.
