Porosity and permeability measurements for selected Paleozoic samples in Quebec

A total of 167 field samples were collected in 2005 and 2006 in order to provide some porosity and permeability data for Paleozoic rocks in Quebec. Samples were collected in the three major tectonostratigraphic domains of the Paleozoic of Quebec; namely the Cambrian-Ordovician shallow marine St. Lawrence Platform (southern Quebec and Anticosti Island), the coeval deep-water sediments preserved in the Taconian Humber Zone (eastern Quebec) and the late Ordovician to Middle Devonian Gaspé Belt (Gaspé Peninsula). Two samples were taken from the thin Carboniferous veneer in southern Gaspé Peninsula. Porosity and permeability measurements were realized at the AGAT laboratories in Calgary. In all domains, some sandstones have relatively high porosity and permeability values. Carbonates are generally characterized by low porosity and permeability values, except for hydrothermal dolomites.
