Summary

The Westphalian A and B of the Pennine Basin is one of the most intensely studied sedimentary successions in the UK owing to its economic importance in the coal and hydrocarbon industries. Previous studies of this interval have utilized the wealth of mining data available to accurately correlate sand bodies and deterministically map their regional extents in a two-dimensional framework. This paper expands on one particular study by taking the same data used by previous workers and digitally processing them into a format that is readable by an oil industry reservoir modelling programme (IRAP-RMS). A three-dimensional deterministic model has then been constructed to allow visualization and analysis of the resulting facies geometries in three dimensions, with the aim of gaining an improved understanding of the geometry and architecture of a major multistorey fluvial sandbody. Application of these techniques has allowed for enhanced visualization and interrogation of the Pennine Basin interval, previously not possible using traditional two-dimensional techniques. Understanding of the Silkstone Rock and its relationship to other facies has improved, because erosion at the base of the unit can be demonstrated to truncate coals and single-storey channel-fills that represent an earlier depositional phase. The visualization of this relationship is not possible from a single two-dimensional section, and the three-dimensional model therefore clarifies stratal relationships.
