Classical diagenesis studies make use of a wide range of methods and analytical techniques in order to suggest conceptual models that explain specific, relatively time-framed, diagenetic processes (like dolomitisation) and their impacts on reservoirs. Modern techniques usually combine petrographic analyses (by means of conventional, cathodoluminescence, fluoresence, and scanning electron microscopic techniques), geochemical measurements (major/trace elements, micro-probe, stable oxygen and carbon isotopes, Sr radiogenic isotopes) and fluid inclusion analyses, providing independent arguments to support the proposed model. Still, conceptual models are qualitative and do not yield "real" data for direct use by reservoir engineers for rock-typing and geomodelling. This contribution provides new insights into numerical modelling of hydrothermal dolomitisation.
