Tutors: Huw Williams (Reservoir Geology Consultants Limited) Paul Davies (Reservoir Geology Consultants Limited) Duration: A five day field and classroom-based reservoir geology and modelling course based in Lexington and Prestonsburg, East Kentucky Outline: 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. Overview: 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

Content: 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 sedimentolgy and sequence stratigraphic concepts. The primary topics covered in the course are:

1. Diagnostic outcrop, core and log interpretation of coal-bearing fluviodeltaic environments and facies

2. Building conceptual models and a sequence stratigraphic framework in coal-bearing sediments for reservoir modelling

3. Coal and coal-bearing sediment correlation techniques from well data 4. Deterministic modelling techniques for coal-bearing sediments using Petrel 5. Using Petrel hierarchy, zone logs and layering 6. Comparison of modelling results from different Petrel techniques

Training Method and Physical Demand The course blends outcrop instruction with corresponding instruction in building 3-D Petrel models of the same outcrops. Generally, the mornings are spent in the field with afternoon classroom-based modelling sessions. The physical demands for this class are easy. The field sites are all roadside stops in the Appalachian foothills of East Kentucky at altitudes of 200-500m. In October the weather is generally sunny with daytime temperatures of 16-21o 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.

Modern Mississippi analogue, Kentucky outcrop and reservoir model of coal seam splits and genetically-related distributary channel-levee complexes which typify coastal plain deposits Who Should Attend ? This class is for geoscientists who are interested in characterising and realistically modelling coal-bearing sedimentary architecture to support conventional hydrocarbon or coal bed methane and underground coal gasfication 3-D modelling projects.
