Abstract

Integrated field and subsurface studies of the Albian Torok and Nanushuk formations (coeval clinoform and topset couplet) have produced a sequence stratigraphic framework for identifying fairways most likely to contain stratigraphic traps in Brookian turbidites in NPRA (Fig. 1). Stratigraphic traps in the Torok involve lowstand, sand-rich turbidite facies sealed by condensed mudstones deposited during transgression. The lowstand deposits commonly downlap onto, and interfinger basinward with, oil-prone source rocks of the gamma-ray zone (GRZ), an Aptian-Albian condensed section (Fig. 2).
