Abstract


This study focuses on the reservoir characteristics of a Permian

tight gas field in the Southern Permian Basin, Eastern Frisia, Germany. To

improve the understanding of the reservoir, 3D seismic, wireline and core

data were compared with a reservoir analogue in the Panamint Valley, United

States. Depositional environments of the Permian Upper Rotliegend II include

perennial saline lakes, coastal parallel sand belts comprising wet, damp and dry

sand flats and aeolian dunes with interdune deposits. Polygonal patterns at different

scales were observed on seismic horizon slices in the reservoir intervals

and the overlying Zechstein. Outlines of superordinate polygons coincide

with interpreted faults. Similar polygonal networks were identified on modern

dry lakes in the western United States. The kilometre-long, up to 1.20 m deep

open fissures in the Panamint Valley are interpreted to originate from the combined

effects of synaeresis and tectonics. Subsequently, the fissures were filled

with aeolian sediment. Vegetation growth confined to the lineaments indicates

enhanced fluid circulation. Such fissures systems may serve as weakness zones

and fault grain and impact reservoir quality in terms of hydraulic connectivity

of reservoir compartments. For the Rotliegend reservoirs, original porosities

and permeabilities of these zones were reduced to a minimum by enhanced

cementation along the fluid migration pathways. Permeability barriers and reservoir

compartmentalization, which can be clearly depicted on seismic attribute

volumes, are a potential result of this development.
