Abstract (englisch):


Conventional and tight sandstone reservoirs are still prominent targets for oil and gas exploration. Although well known, any kind of improved reservoir quality prediction may improve the return of invest. Our approach is a better understanding of reservoir quality in a 3D carbonate- and siliciclastic rock body based on thorough reservoir characterization using novel approaches (Becker et al., 2018a; Becker et al., 2017a; Busch et al., 2019; Busch et al., 2018; Wüstefeld et al., 2018; Wüstefeld et al., 2017) With a focus on siliciclastic rocks, we present an overview of our approaches. We show that micrometer-thin clay coatings have a tremendous effect on reservoir quality, that quartz overgrowth can be used to calibrate subsidence curves and that faults may act as heat conduits affecting the maturation of fields on the reservoir scale.

Geological Setting

Our target areas are the conventional and tight, gas-producing siliciclastic fields of Northern Germany, which can be found in the Rotliegend eolian red bed formations (with reservoir qualities in the range of 0.01 to 1000 mD) and the Upper Carboniferous sandstone units (with reservoir qualities in the range of 0.01 to 100 mD). ... mehr
