Hopeman aeolian sandstones north sea
WebMany excellent aeolian sandstones suffer a decline of reservoir quality associated with structural compartmentalization by tectonic features. An onshore analogue, the Permo-Triassic Hopeman Sandstone, which crops out along the Southern side of the Moray Firth, Scotland, has been studied due to the difficulty in quantifying tectonic heterogeneities in … WebThe Hopeman Sandstone is a cross-bedded sandstone of Permo-Triassic age that crops out in coastal exposures in northeastern Scotland.

WebAbstract: Sandstones of the Main Buntsandstein Subgroup represent a key element of the well- established Lower Triassic hydrocarbon play in the southern North Sea area. Mixed aeolian and fluvial sediments of the Lower Volpriehausen and Detfurth Sandstone members form the main res- ervoir rock, sealed by the Solling Claystone and/or Röt Salt.

WebThe thesis provides a comparative study of both sedimentology and diagenesis of Lower Permian (Rotliegend) strata, onshore and offshore U.K. (Southern North Sea). Onshore formations studied include the Bridgnorth, Penrith and Hopeman Sandstone, and are dominated by aeolian facies, with lesser amounts of interbedded fluvial sediments. Web20 dec. 2024 · Nagtegaal has reported that fluvial sands tend to be moderately to poorly sorted trends, reducing reservoir quality which is suggested in aeolian sands. Fluvial sandstones have lower reservoir quality than those in aeolian facies; this might refer to the fact that the fluvial sands have well-cemented dolomite in Rotliegend in the Sothern …
Web1 jan. 2011 · The Rotliegend gas play in the Southern Permian Basin has yielded over 200 gas fields in the Netherlands; they are found in an E–W fairway along the southern flank of the basin. Sandstones generally pinch out basinward, but localized, isolated sands are present north of the main fairway.
