          • Definition(s)
            • Volumen de espacios vacios dentro de la roca que pueden ser ocupados por fluidos (agua, gas, petroleo,etc). Se expresa en porciento del volumen total de la roca. Por ej. 20% de porosidad significa un 20% de espacios vación dentro de la roca. Own research - by caere
          • Example sentence(s)
            • La porosidad útil es, en general, inferior en un 20-50% a la total, dependiendo, sobre todo, del tamaño de grano de la roca: cuanto menor sea este tamaño de grano, más baja será la porosidad útil respecto a la total. También influye la forma de los granos. - monografías.com by caere

          • Definition(s)
            • The volume of spaces within rock that might contain oil and gas (like the amount of water a sponge can hold); the open or void space within rock – usually expressed as a percentage of the total rock volume. Thus porosity measures the capacity of the rock to hold natural gas, crude oil or water. Canadian Association Petroleum Producers
          • Example sentence(s)
            • 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
