Abstract
With ever improving 3D seismic, the trend in static reservoir modelling is towards more direct constraining of 3D-model reservoir architecture by the seismic data. Whilst seismic constraining can result in more realistic, better quality reservoir architecture models, there are a number of key problems to overcome namely: 1) limited vertical resolution of the seismic; 2) limited ability to capture sedimentary body-shapes (e.g., channels and bars) by variograms; and 3) limited ability for geostatistics-based modelling algorithms to capture spatial facies associations in a geologically realistic manner. This paper discusses a number of different approaches to reservoir architecture-model constraining by 3D seismic based on some actual field examples, to distil best practice methods and guidelines. The emphasis in this paper is on clastic reservoir settings with complex “labyrinth-type” reservoir architecture.
