The 1994 discovery of the Alpine oil field (>400 MMBO recoverable), a subsequent Federal lease sale in northeast NPRA, and the 2001 announcement of discoveries of commercial quantities of hydrocarbons in Alpine-type traps within NPRA (Fig. 1) have reinvigorated exploration interest in a formerly moribund part of the Alaska North Slope. Limited data available in the public domain suggest that key ingredients of Alpine-type accumulations include a high gravity oil charge apparently sourced from a condensed section in the Lower Jurassic and stratigraphic traps in the Upper Jurassic comprising a transgressive assemblage of lenticular, fine-grained, well winnowed shoreface sands deposited in erosional incisions and sealed by condensed mudstone (Figs. 2 and 3).
