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 ...

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.

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 ...
