DESCRIPTION:Speakers: Ntombizodwa Mosete ()\nLimestone is a calcareous roc
 k and is among the common hydrocarbon reservoirs (others being dolostone\,
  sandstone and unconsolidated sands). Carbonate reservoirs hold a signific
 ant percentage of the world's oil and gas reserves. This study explores th
 e nanopore structure of calcitic and dolomitic limestone by virtue of them
  being abundant in the chosen area of study. The difference between these 
 two types of limestones is their magnesium carbonate content\, calcitic li
 mestone has about 5% of magnesium carbonate while dolomitic limestone has 
 about 40%. By characterizing the nanopore structure\, the intent is to det
 ermine the fluid transport capabilities of the limestones under study. The
  results of the study will be beneficial to the energy resources explorati
 on and add on to the understanding of pore systems in limestone. \nA reser
 voir\, body of porous rock that contains fluids (water and/or hydrocarbons
 ) and in which these fluids can migrate\, is controlled by two key propert
 ies\, which are porosity and permeability. These properties are further in
 fluenced by other parameters such as pore size\, pore diameter\, pore thro
 at radius\, pore coordination number and pore size distribution. \nThis pr
 esentation gives an account of sample preparation of the limestones for an
 alysis using small angle scattering (SAS) techniques\, small angle light s
 cattering (SALS) and small angle x-ray scattering (SAXS) in particular. SA
 LS can structurally characterize materials with pore diameters in the sub-
 micron range and SAXS is effective in characterizing nano-range structured
  materials.\n\nhttps://events.saip.org.za/event/206/contributions/7105/
