Faulting of salt-withdrawal basins during early halokinesis: Effects on the Paleogene Rio Doce Canyon system (Espírito Santo Basin, Brazil)

“…Also, most of the published works on salt-sediment interactions in the Gulf of Mexico and Africa are based on 2-D seismic data on late Cenozoic canyon systems (e.g., McBride et al, 1998;Rowan et al, 1998;Weimer et al, 1998;Babonneau et al, 2004) or on older three-dimensional (3-D) data (e.g., Jennette et al, 2003) whose quality, in comparison with the studied 3-D seismic cube, hindered (1) the complete recognition of the geometry of postsalt fault sets and (2) the imaging of significant fault families not observed on other Atlantictype margins (e.g., Mars-Ursa canyon; Sawyer et al, 2007). Therefore, to improve our understanding on postsalt overburden faulting and its effects on hydrocarbon-play development across a salt-rich continental slope, accurately dating the onset of gravitational tectonics and associated phases of structural reactivation of postsalt strata will undoubtedly assist hydrocarbon exploration in deep-water prospects (e.g., South Atlantic, west Iberian margin, Canada or Norway) where thick evaporite units of distinct ages physically divide potential subsalt plays from reservoir rocks (Guardado et al, 2000;Faerseth and Lien, 2002;Magoon et al, 2005;Alves et al, 2006;Jackson and Harrison, 2006).…”

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.…”

Mechanisms of petroleum accumulation in the Bozhong sub-basin, Bohai Bay Basin, China. Part 1: Origin and occurrence of crude oils

“…Oils originated from the Shahejie Formation source rocks in the Bozhong depression experienced relatively long-distance lateral migration and accumulated in traps away from the generative kitchen, whereas oils originated from the Dongying Formation migrated only a short distance and accumulated in traps closer to the generative kitchen. As a result, the geographic extent (Magoon and Dow, 1994;Magoon et al, 2005) of the Dongying(!) petroleum system is much smaller than the geographic extent of the Shahejie(!)…”

“…In such an intensely explored area, clearly characterizing potential source rocks (e.g., Keym et al, 2006;Justwan et al, 2006), classifying discovered hydrocarbons into sourcerelated families (e.g., Peters et al, 1994;Snowdon et al, 1998;Yurewicz et al, 1998;Abrams et al, 1999;Pasadakis et al, 2004;Greene et al, 2004;Justwan et al, 2006), determining the geographic extent of operating petroleum systems (Magoon and Dow, 1994;Magoon et al, 2005) and reasonably predicting petroleum migration pathways (Hindle, 1997;Hao et al, 2007) have been confirmed very useful for optimizing petroleum exploration. This is the first part of a large study program aiming at understanding the operating petroleum systems, classifying discovered oils into source-related families and revealing the major factors resulting in the distinct oil distribution pattern in the Bozhong subbasin.…”
