The focus of the study is to test the recent sequence stratigraphic interpretation of the Ca2 (Strohmenger et al. 1996a, Fig. 4), to quantify factors governing sedimentation and their impact, and, as a consequence, to improve the
prediction of reservoir facies distribution.

Basic Data Set
The recognition and adequate understanding of depositional sequences are basic preconditions for designing optimal models for predicting sequences, facies
patterns and reservoir distribution (Wanless 1991). The Ca2 meets these conditions.
The basic data for the high-resolution forward stratigraphic modeling of the
Ca2 come from two areas, the northwest German South Oldenburg area and the
east German southeast Brandenburg area (Fig. 2). The Ca2 in both areas has
