Characterisation and Petrel* 3-D Modelling of Fluvio-Deltaic Sedimentary Architecture, Upper Carboniferous, East Kentucky

A five day field and classroom-based reservoir geology and modelling course based in Lexington and Prestonsburg, East Kentucky

This is a reservoir characterisation and modelling course focused on capturing the geological knowledge necessary to build realistic models of coal-bearing fluvial and deltaic sediment body architecture using Petrel. The course follows the typical workflow of a sub-surface 3-D modelling study and is aimed at fluvio-deltaic reservoir characterisation and making realistic predictive models of sedimentary geometries and architecture by incorporating detailed knowledge of sedimentology and sequence stratigraphic concepts.

Outcrops, cores and well logs are studied to characterise both small and large-scale patterns of sedimentary architecture within a sequence stratigraphic framework in these Carboniferous coal-bearing fluvio-deltaic sediments.

  • Audience

    This class is for geoscientists who are interested in characterising and realistically modelling sedimentary architecture to support hydrocarbon, coal-bed methane or coal extraction.

  • Prerequisites

    The course blends instruction at outcrop with corresponding classroom instruction in building 3-D models of the same outcrops. Generally, the mornings are spent in the field with afternoon classroom-based modelling sessions. A working knowledge of Petrel* is necessary to obtain the maximum benefit from the class.

    The physical demands for this class are easy according to our field course grading system. The field sites are all roadside stops in the Appalachian foothills of East Kentucky at altitudes of 200-500m. In early November the weather is generally sunny with daytime temperatures of 5-14o c with cooler evening temperatures. The terrain comprises man-made road-cuts through gentle rolling wooded hills. Transport is by minibus on black-top roads. There will be some walking up onto and along lower level road-cut benches.
