Controls on reservoir quality in exhumed basins - an example from the Ordovician sandstone, Illizi Basin, Algeria
文摘
Integrated study linking petrographic observations with numerical modelling of diagenesis. Best reservoir quality found in high-energy, tidally reworked, post-glacial sandstones. Quartz cement volume and reservoir quality varies across the field within similar facies. Spatial variation in reservoir quality linked to variable thermal history across the field.
