English term or phrase:porosity
Definition from Canadian Association Petroleum Producers: 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.
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
Definition from own experience or research: A porozitás a pórusok százaléka az egységnyi térfogatban.
Example sentence(s):
A kõzetek porozitása kialakulhat elsõdlegesen, azaz ülepedéskor vagy megszilárduláskor (pl. gázbuborékok a hólyagos bazaltban, szemcseközi hézagok a törmelékes üledékekben), ez azonban a diagenezis, illetve majd a metamorfózis során fokozatosan bezáródhat, eltûnhet. Másodlagos porozitásnak nevezik a már kialakult kõzetben kinyíló repedések és egyéb folyamatok (pl. karsztosodás, fúrókagylók rögzülése stb.) nyomán keletkezõ pórusteret. Miután a pórusok fluidumok (pl. víz, szénhidrogének) tárolói és áramlási útvonalai lehetnek, fontos, hogy összeköttetésben állnak-e egymással, más szóval mekkora az átmenõ porozitás aránya a teljeshez képest. A porozitás nagymértékben befolyásolja a kõzet látszólagos sûrûségét is. - Miskolci Egyetem
