Controls on reservoir distribution, architecture and stratigraphic trapping in slope settings

Tectonostratigraphy of a rift basin affected by salt tectonics: synrift Middle Jurassic–Lower Cretaceous Dutch Central Graben, Terschelling Basin and neighbouring platforms, Dutch offshore

“…This topic has been considered extensively in clastic deep-water settings affected by salt tectonics (e.g. Booth et al 2003;Prather 2003), carbonate settings affected by salt tectonics (e.g. Giles & Rowan 2012), continental settings (e.g.…”

Deep-water canyons and sequence-stratigraphic framework of the Upper Jurassic Naknek Formation, south-central Alaska

“…The seismic-scale exposures in the Chisik Island, Hickerson Lake, and Mount Pomeroy areas are interpreted as the record of processes, products, and associations with deep-water canyons ( fig. 12), which we define as broad (fill is kilometers wide), deep (fill is hundreds of meters thick), erosive-based, slope-associated conduits for transport of mud, sand, and gravel in deep-marine environments (compare with Shepard, 1981;Pickering and others, 1989;Reading and Richards, 1994;Galloway and Hobday, 1996;Galloway, 1998;Richards and others, 1998;Posamentier and Allen, 1999;Prather, 2003;Weimer and Slatt, 2007;Jobe and others, 2011;Williams and Graham, 2013). Scale alone is commonly insufficient to distinguish between slope channels and canyons-although the latter are in general larger than the former-but it is the markedly erosional character and complex, composited, and long-lived evolution of marine canyons that differentiate them from deep-water channels (Galloway, 1998) that themselves form part of the process-response framework of canyon-associated depositional systems.…”

“…Sand-prone canyon-fill successions broadly analogous to those described above are recognized throughout the world for their reservoir potential (for example, Cronin and Kidd, 1998;Stow and Mayall, 2000;Prather, 2003;Satur and others, 2005;Mayall and others, 2006;Jobe and others, 2011). The dominantly coarse-grained canyon fills of this study were probably supplied from sandy fluvial and shallow-marine environments ( fig.…”

“…Additionally, the interpreted clastic wedge of LST-2 basin-floor fans that onlapped the Snug Harbor slope ( fig. 14) may be prone to stratigraphic trapping if overlying deep-water seal facies cap LST-2 (compare with Prather, 2003).…”

3D Seismic Sedimentology of Nearshore Subaqueous Fans – A Case Study from Dongying Depression, Eastern China

“…Since its first introduction in 1998 (Zeng et al, 1998), the concept has been applied in the identification of paleorivers, the sedimentary facies and sedimentary environment evolutions of carbonate platform and the slope fans with many good results (Carter, 2003;Chen.& Meng, 2004;Crumeyrolle et al, 2007;Darmad et al, 2007;Gee & Gawthorpe, 2007;Handford & Baria, 2007;Ling et al, 2005;Lin et al, 126 2007;Liu, B.G. & Liu, L.H., 2008;Nordfjord et al, 2005;Posamentier & Killa, 2003;Prather, 2003;Sullivan et al, 2007;Schwab et al, 2007;Wang et al , 2004;Wu et al, 2005;Zeng et al, 2003Zeng et al, , 2004Zeng et al, , 2007Zhang et al, 2007), but rarely used to study nearshore subaqueous fans. In this paper, we took the nearshore subaqueous fan in the Dongying Depression as a case, and used the pseudo-acoustic 3D seismic inversion method on characteristic logs to reconstruct 3D seismic sedimentological structures of the nearshore subaqueous fans including the distribution of the effective sand-conglomerate reservoirs and the temporospatial evolution of individual nearshore subaqueous fan system.…”
