- Abstract
Low permeability core is analyzed using a combination of Nuclear magnetic resonance, Nitrogen adsorption, and Mercury injection capillary pressure. The material's surface area and pore size distributions were determined using Brunauer-Emmett-Teller and Barrett-Joyner-Halenda methods, respectively. Results indicate pores in the 2~ 10nm size ranges have a high percentage. The core displayed high irreducible saturation due to the volume of small pores. Mesopore of type V was identified from study carried out. Capillary pressure correlation between nuclear magnetic resonance and mercury injection show good agreement, however discrepancy in total pore volume was observed.
