Reactive Transport Models of Limestone-Dolomite Transitions: Implications for Reservoir Connectivity

Substantial volumes of world hydrocarbon resources occur in<br>interlayered limestone-dolomite reservoirs. Diagenetic<br>variations in lithology and primary depositional texture control<br>the magnitude and spatial distribution of petrophysical<br>properties. The frequency and nature of limestone-dolomite<br>transitions that define flow units and baffles/barriers are<br>critical for understanding reservoir connectivity and<br>optimizing field development.
