Step 1: Separate routine core analysis from special core analysis:
Core analysis is generally split into routine core analysis, which measures porosity and permeability quickly on many plugs, and special core analysis, which measures more detailed properties such as pore size distribution, relative permeability and capillary pressure on selected plugs. Both categories are laboratory measurements performed on the physical core sample itself.
Step 2: Assign option A, porosity, to routine core analysis:
Porosity comes directly from routine core analysis, where the grain volume and bulk volume of the plug are measured and the pore volume fraction is calculated. This is a direct, sample scale measurement, so option A belongs to the list of properties obtained from a core sample.
Step 3: Assign option B, pore size distribution, to special core analysis:
Pore size distribution comes from special core analysis, typically the mercury injection capillary pressure test or nitrogen adsorption for tighter rocks, both of which are run on a piece of the core plug in the lab. Since this measurement is only possible with a physical sample, option B also belongs to the list.
Step 4: Assign option C, absolute permeability, to routine core analysis:
Absolute permeability is obtained by flowing a single fluid through the plug at fixed conditions and using Darcy's law, again a routine core analysis test performed on the physical sample, so option C belongs to the list as well.
Step 5: Rule out option D, reservoir boundary:
Reservoir boundary is a large scale, field level property describing the outer limits and connectivity of the reservoir, and it cannot be read off a centimeter scale rock plug. It is instead established using seismic mapping, multi well correlation, and pressure transient well tests that see a much larger drainage area, so option D is excluded.
Final Answer:
\[ \boxed{\text{Options A, B and C: porosity, pore size distribution and absolute permeability}} \]
