“…The Ameland lake-level highstand (ca. 260 Ma; Gast, 1991;Legler and Schneider, 2008) coincided with the onset of sedimentation in the study area. Following deposition of the reservoir interval, the study area underwent several lake-level fl uctuations (e.g., Legler and Schneider, 2008).…”

“…260 Ma; Gast, 1991;Legler and Schneider, 2008) coincided with the onset of sedimentation in the study area. Following deposition of the reservoir interval, the study area underwent several lake-level fl uctuations (e.g., Legler and Schneider, 2008). Core data of the Upper Rotliegend II sediments in the study area revealed that these are of fl uvio-eolian origin, including braided stream, sheetfl ood, eolian dune, and wet to dry interdune deposits of the Wustrow and Bahnsen Members (ca.…”

Comparison of modern deposits in thePanamint Valley, western United States, to core and geophysical data from a Permian (Rotliegend, Germany) tight gas fi eld allows for improved understanding of the interaction of tectonics and sedimentary processes during Rotliegend deposition. The Panamint Valley was selected for a modern analog of the subsurface Rotliegend Basin because both study sites are characterized by (1) elongated grabens with large-scale bounding fault zones resulting from synsedimentary transtensional tectonics; (2) fault-controlled paleotopography as key controlling parameter for the sediment facies distribution, including alluvial fans, dunes, wet and damp interdune sandfl ats, and ephemeral dry lake deposits; and (3) local sediment provenance from sedimentary and volcanic rocks. The analysis of satellite images and fi eld data from the Panamint Valley enabled the development of a conceptual model involving topography, synsedimentary faulting, and wind activity as controlling factors for the sediment facies distribution. The application of the model to the reconstructed Rotliegend paleotopography of the German subsurface study site allows for prediction of the facies distribution prior to the Triassic-Cretaceous tectonic overprinting. As a consequence, we expect a sediment facies succession from (1) alluvial fan deposits along the hanging walls of the basin-bounding fault zones to (2) distributary fl uvial channel deposits toward the basin center and (3) ephemeral lake deposits in the deepest basin area. (4) Eolian dune accumulation and preservation is mainly concentrated on hanging-wall locations. However, additional dune deposits are proposed above overlapping step faults and on footwalls of synsedimentary active faults. (5) Sandfl ats occur on the upwind and downwind margins of the dune fi eld. These predictions are calibrated to core and geophysical well log data.

Geo log i cal Quar terly, 60 (4): 771-800, doi: 10.7306/gq.1336The Up per Rotliegend de pos its of the west ern part of the Poznañ Ba sin, Po land, rep re sent three main sed i men tary en vi ronments: ae olian desert (dunes and sand sheets), al lu vial plain (al lu vial cov ers with wadi de pos its) and mar ginal playa. In arid pe ri ods, dunes prograded into ar eas dom i nated by al lu vial sed i men ta tion. Dur ing wet pe ri ods, al lu vial de pos its eroded the ae olian de pos its and prograded onto dune fields. Playa sed i ments were de pos ited among ae olian or al lu vial sed i ments during pe ri odic ex pan sions of the playa. These aeolian, allu vial and playa de pos its are ar ranged in depositional se quences. Bound aries be tween se quences are marked by rapid changes in depositional fa cies; and by ero sional bound ing sur faces. Max i mum Wet ting Sur faces have been dis tin guished within some parts of the depositional se quences, which en able regional cor re la tions.

Sys tems of sand sheets are typ i cal of mar ginal ar eas of ergs. We dis tin guish nine depositional com plexes (units) num bered 1-9 from base to top, re spec tively. These sub di vi sions are based on the in ter pre ta tion of the sedimentological re cord in palaeoclimatic terms, and in terms of ma jor ero sional bound aries, which are prob a bly of re gional ex tent.

Uncertainty in static CO₂ storage capacity estimates: Case study from the North Sea, UK

et al. 2013

We used a sub‐salt Rotliegend Group sandstone saline aquifer in the North Sea as a case study site for Monte‐Carlo‐based CO2 geostorage capacity assessment. In the area of interest, this unit is characterized by sparse, low resolution, subsurface data typical of the margins of global petroleum provinces, favored for CO2 storage. Such data scarcity leads to uncertainty regarding the complex trap geometries and ultimate CO2 storage capacity. The Rotliegend reservoir, estimated to have porosity and permeability ranges of 11–27% and 0.2 mD–125 mD, respectively, is sealed by Zechstein salt. The salt, predominantly halite, is a proven hydrocarbon seal in the central and southern North Sea hosting oil and gas columns of >140 m (>450 ft) and >150 m (>500 ft). Utilizing 2D‐seismic data, boreholes and analogues, we estimate the pore volume of a 5‐km2 4‐way dip‐closed structure through Monte‐Carlo‐based capacity simulations. We estimated storage capacity using published methodologies and compared this against a theoretical total storage calculation analogous to the gas in place equation used in the petroleum industry. We found that different methods yield a capacity range of <104 to >109 tonnes CO2 where sensitivity analysis indicates variability in reservoir properties to be the dominant control. Thus static estimates based upon Monte‐Carlo calculations present no advantage over theoretical pore volume estimations. This leaves 3D dynamic modeling of storage capacity populated by 3D seismic data and direct down‐hole measurement of reservoir properties to improve confidence in capacity estimations as the recommended method.
