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 ...

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 ...

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.

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 ...
