English term or phrase:
porosity
Portuguese translation:
porosidade
English term
porosity
The porosity profile in any individual well depends on the maximum effective stress, which is generally determined by the maximum burial depth. (U.S. Geological Survey)
Carbonate reservoirs have lower values of median and maximum porosity for a given burial depth, probably because of greater chemical reactivity of carbonate minerals relative to quartz and the resulting lower resistance to chemical compaction and associated cementation. (GeoScienceWorld)
Porosity and permeability reduction due to burial and compaction acts differently on different sediment types. Sandstone is more resistant to porosity and perm reduction due to compaction, whereas shales and siltstone are generally more prone to perm reduction. (All Experts)
