Additional field(s): Geology
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

porøsitet


Definition from own experience or research:
Porøsitet er andelen av porer i et fast stoff som kan fylles med gass eller væske (f.eks. CO2, olje eller vann).

Example sentence(s):
  • P. er den andelen av bergarten som kan fylles med gass eller væske (f.eks. olje eller vann). - Caplex  
  • Porøsiteten til et materiale er et mål for forholdet mellom volumet av porer i materialet og totalvolumet. Vanligvis måles porøsiteten som et desimaltall mellom null og én eller som en prosentandel. For filtermaterialer brukes også en alternativ definisjon av porøsitet, som ikke er basert på volum. Poretettheten måles i måleenheten PPI, pores per linear inch eller porer per lineær tomme. - Wikipedia  

Explanation:
Porøsitet handler i denne sammenheng om porøse bergarter der porene kan fylles med væske eller gass. I dagligtale er porøsitet langt mer: Sjokoladekjennere vil regne Stratos som et merke med høy porøsitet, uten at den er kjent for sin evne til å fylles med gass eller væske etter ferdig fremstilling. En svamp er porøs, men det er vanskelig å fylle den med væske uten at det meste renner ut igjen.
