Permeability model of tight reservoir sandstones combining core-plug and miniperm analysis of drillcore; longyearbyen co2lab, Svalbard
Permeability measurements in Mesozoic, low-permeability sandstone units within the strata cored in seven drillholes near Longyearbyen, Svalbard, have been analysed to assess the presence of aquifers and their potentials as reservoirs for the storage of carbon dioxide.

| Summary: | Permeability measurements in Mesozoic, low-permeability sandstone units within the strata cored in seven drillholes near Longyearbyen, Svalbard, have been analysed to assess the presence of aquifers and their potentials as reservoirs for the storage of carbon dioxide. These targeted sandstones are located in the Upper Triassic–Lower Jurassic De Geerdalen and Knorringfjellet formations, with some permeability found in the Cretaceous Rurikfjellet and Helvetiafjellet formations situated within otherwise impermeable cap-rocks. Permeability and porosity data were acquired from drill plugs, analysed in the laboratory by flooding of H 2 O, He and Hg, and compared with direct measurements collected manually from cores with a Miniperm instrument. The sandstones are tight ( |
