The Egret Member, a Prolific Kimmeridgian Source Rock from Offshore Eastern Canada

Egret-Hibernia(!), a significant petroleum system, northern Grand Banks area, offshore eastern Canada

“…However, sterane distributions in rock extracts from the Jeanne d'Arc Formation suggest that this shale would expel terrigenous oil unlike that from the Egret Member . Fowler and McAlpine (1994) show that the Voyager Formation would similarly expel terrigenous oil, but contrary to von der Dick's result, the Jeanne d'Arc Formation would expel marine oil similar to that from the Egret Member. According to Fowler and McAlpine (1994), the limited lateral extent of the Jeanne d'Arc and Voyager source rock units suggests that they have never generated volumetrically significant accumulations.…”

“…Many investigators determined that the Egret Member of the Rankin Formation is the principal source rock of the Jeanne d'Arc petroleum province (Swift and Williams, 1980;Powell, 1985;Creaney and Allison, 1987;von der Dick, 1989;von der Dick et al, 1989;Bell and Campbell, 1990;Williamson, 1992;Huang et al, 1994Huang et al, , 1996Fowler and McAlpine, 1994;Prokoph and Agterberg, 2000). (C) Size of each discovery decreases between each third (by order of discovery) and within each third.…”

Basin modeling meets rift analysis – A numerical modeling study from the Jeanne d'Arc basin, offshore Newfoundland, Canada

“…It is the only mature source rock on the Grand Banks (Fig. 2) (Fowler and McAlpine, 1994;Huang et al, 1996;Hubbard, 1988;Magoon et al, 2005;Swift and Williams, 1980;von der Dick, 1989;von der Dick et al, 1989). Different hiatus and/or unconformities, ranging in age between middle Kimmeridgian and Albian, define the ''Avalon Uplift'', an Early Cretaceous regional tectonic event, which eroded deeply into source and reservoir rock intervals (Fig.…”

“…Analyses of cuttings have indicated up to 8 wt% TOC with the majority of the samples in the 2-5% range. Average HI (Hydrogen Index) values where the member is immature range from 500 to 700 and in OI (Oxygen Index) vs HI plots the organic matter plots in the Type II organic matter field (Fowler & McAlpine 1994). Burial history studies show that the peak oil generation from the Egret Member began at approximately 50 Ma in the Early Tertiary (Fig.…”

“…Fowler & McAlpine (1994) show thick, mature Kimmeridgian source rocks extending onto the Outer Ridge Complex (Fig. 9) and these were drilled in the Panther P-52 well.…”
