Understanding the petrophysical character of sedimentary basin fill is of prime importance to modeling studies that aim to develop quantitative descriptions of the hydrocarbon charging histories of Canada's frontier basins. The petrophysical characterization of basinal reservoirs in terms of their hydraulic, electric, and elastic properties and their evolution with burial and compaction are key to an understanding of secondary migration pathways. Digitized log data from penetrations of the Jeanne d'Arc Formation reservoir at the Terra Nova and Hibernia oil fields have been used to determine three groups of physical parameters: petrophysical parameters, including porosity, permeability, and lithologic components; electric parameters, including water saturation, bulk and water resistivi ies, electric tortuosity, formation resistivity factor, cementation factor, specific internal surface area, and grain size distribution; and elastic parameters, including the elastic moduli in terms of rigidity and compressibility, Young's modulus, Poisson's ratio, and velocity ratio. These parameters show the Jeanne d'Arc Formation to be highly heterogeneous. This heterogeneity is demonstrated through a comparison of parameter variability within and between the Terra Nova and Hibernia oil fields.
