Sedimentary facies reconstruction and kinematic restoration of an Upper Permian tight gas field, north-western Germany
… reservoir, located at ~4200 metres depth in the Upper Rotliegend II (Upper Permian) of north-western Germany, includes a geological framework model for the sedimentary facies distribution, which is strongly influenced by the structural grain. Research focused on unravelling the structural and …

Characterization of an Upper Permian tight aas reservoir : a multidisciplinary, multiscale analysis from the Rotliegend, Northern Germany
… initially on the facies architecture of a Permian tight gas field in the Southern Permian Basin (SPB), East Frisia, Northern Germany. To improve field development, 3D seismic data, wireline and core data were compared to a reservoir analogue in the Panamint Valley, California, United …

Provenance and depositional environments of the upper Permian-lowermost Triassic fluvial and lacustrine sandstones, Wutonggou low-order cycle, Bogda Mountains, NW China
… of compositions and textures of the upper Permian-lowermost Triassic fluvial-lacustrine sandstones, Wutonggou low-order cycle (WTG LC), Bogda Mountains, NW China. In the first part, three petrofacies are identified on the basis of the relative abundances of quartz, feldspar, and …

Diagenesis And Controls On Porosity And Permeability In The Upper San Andres Formation Of West Texas
… Central Basin Platform (CBP) are dominated by Permian-age carbonate deposits, significantly contributing to petroleum production. The Upper Permian-aged San Andres Formation, composed primarily of dolomite and limestone, is a prolific reservoir. This study assesses diagenetic influences on …

Karoo-Etendeka Unconformities in NW Namibia and their Tectonic Implications
… can be subdivided into (1) a Carboniferous-Permian, (2) a Triassic-Jurassic and (3) a Cretaceous megasequence, each recording extensional periods related to successive rifting phases in the evolving South Atlantic. The tectonic environment of the depositories in north-western Namibia changes …

The sedimentology and petrology of the new red sandstone of the Elgin Basin, North East Scotland
… the basin at Elgin, deposition began during the Upper Permian with a series of sheetflood deposits which graded laterally into seif dunes to the north. Deposition during the Triassic is dominated by aeolian barchan dunes although minor point bar, playa and floodplain deposits were' present. A …

Sequence Stratigraphy and Chemostratigraphy Across the Permo-Triassic Extinction Event, Upper Khuff Carbonates, Ghawar Field, Saudi Arabia
Logging of cores of the Upper Permian and Lower Triassic Khuff Formation, Ghawar, Saudi Arabia, has allowed a high resolution sequence stratigraphic framework to be generated. The lithofacies of this huge, arid epeiric ramp succession include: subaqueous -and supratidal anhydrite, tidal flat …
