Abstract
The use of geohistory information to assess the best practice needed for the prediction of top seal properties in exploration is reviewed. An integrated approach combining petrophysical measurements, microstructural characterisation, down-hole tool data with basin modelling and tectonic setting is used to evaluate top seal property evolution. The results are used to highlight the importance of temperature – pressure histories for constraining top seal predictions. The study has incorporated top seal development from a range of basins. The identification and application of property-geohistory trends is used as a basis for a discussion on the prediction of sealing capacity and column heights.
