Diagenetic Processes and Reservoir Heterogeneity in Salt-Encased Microbial Carbonate Reservoirs (Late Neoproterozoic, Oman)

Figure 9

Paragenetic sequence for the studied A2C reservoir. Effects on porosity and permeability are indicated on the right. Near-surface diagenesis predates salt tectonic deformation and is characterized by products of the early marine diagenesis and reflux-related processes. Burial-related stylolites indicate the intermediate burial diagenesis realm. The presence of hydrocarbons and reservoir bitumen defines the deep burial realm that at least partially postdates the salt tectonic phase.
