Ardennes field trip

Evert van de Graaff 
2,5 days with optional extension

Business context

Multidisciplinary discussion of E&P issues based on well exposed analogues of clastic and carbonate reservoirs in Central and Southeastern Belgium (Ardennes).

Who should attend

Geoscientists and petroleum engineers.

Course content

UGS in karstified Carboniferous carbonates at Loenhout / unconsolidated Tertiary sandstones near Louvain / Devonian platform & reefal carbonates / Tertiary karstification in Devonian carbonates / fractured Devonian deltaic clastics. 

Optionally - upon request: outcrops of Carboniferous carbonates and clastics. The shiplift at Ronquières where the Lower Palaeozoic of the Caledonian Brabant Massif is exposed, and where the history of the Energy Industry [coal mining and oil & gas] is discussed.

Learning, methods and tools

In multidisciplinary groups discuss reservoir characterisation, field development and drilling engineering issues based on outcrop analogues. 

Transport: Coach- or alternatively - self drive.
