Abstract. Permeability is one of the most important petrophysical parameters to describe reservoir properties sedimentary rocks, pertaining problems in hydrology, geothermics, and hydrocarbon analysis. Outcrop analogue studies, well core measurements, individual sample analysis take advantage a variety commercially available devices for permeability measurements. Very often, data derived from different need be merged within study (e.g. outcrop minipermeametry lab-based plug measurements). To...
The Cenozoic East African Rift System (EARS) extends from the Red Sea to Mozambique. Here we use seismic reflection and bathymetric data investigate tectonic evolution of offshore branch EARS. indicate multiple time transgressive neotectonic deformations along ~800 km continental margin northern We observe a transition mature rift basin in north juvenile fault zone south. respective timing deformation is derived detailed stratigraphy. In north, ~30 wide more than 150 long, N-S striking...
Here we report on a ‘fossilized’ sand sea that was progressively engulfed by the basal Etendeka flood basalts in NW Namibia. Preserved relict aeolian landforms include transverse barchanoid dunes and isolated barchan dunes. Present‐day preferential erosion of lava flows exhumes bedforms preserved position which they were migrating at time burial ( c. 133 Ma). A passive eruption style inflated pahoehoe has without significant deformation. The sediment interlayers record decrease supply change...
Diagenetic processes alter petrophysical properties, such as porosity and permeability, of clastic sediments. An understanding these is therefore pivotal for any reservoir quality assessments. Thermal exposure among the crucial factors influencing diagenesis can vary significantly in widespread formations, e.g. due to regional variations burial history. Especially quartz overgrowth controlled by temperature we here demonstrate effect spatial thermal variability on degree cementation. Our...
Upper Carboniferous Coal Measures strata have been interpreted traditionally in terms of cyclothems bounded by marine flooding surfaces (marine bands) and coal seams. Correlation such an extensive grid closely spaced exploration boreholes provides a robust stratigraphic framework which to study the Lower (Namurian C–Westphalian A) Ruhr district, north‐west Germany. Three distinct types cyclothem are recognized, based on their bounding internal facies architecture. (1) Type 1 bands. Each...
ABSTRACT The ephemeral braided Hoanib River of NW Namibia flows for a few days year, and only high discharges enable the river to pass through interdunal depressions within northern Namib Desert dune field Atlantic. comprises mainly large transverse dunes resulting from predominant SSW winds. flood deposits between aeolian are analogous mudstone layers conformably interbedded with ancient aeolianite foresets. Deep floods pond laterally considerable depths (metres >10 m) in adjacent...
