Abstract

Reaction transport models (RTMs) permit quantitative investigation of diagenesis and its effects on reservoir quality. The RTM TOUGHREACT is used to investigate diagenesis in an isolated platform driven by geothermal (‘Kohout’) convection of seawater, which has been invoked to explain dolomitisation during early burial. Previous short (0.1 Ma) RTM simulations suggested that convection can drive dolomitisation, mostly at >50°C, and anhydritisation, but complete dolomitisation requires >30-60 Ma. Our more extended RTM simulations (
