The upscaled BHI facies is used to validate certain aspects of the seismic facies interpretation and to confirm the depositional environment. The lower part of the static borehole image log is much more resistive and homogeneous than the upper part. The dynamic image reveals that sponges dominate this interval and are the main recognizable bioherm-building organisms (E, F). This supports the seismic facies interpretation and confirms furthermore the sequence boundary, which is a karstified flow-zone. The upper part of the borehole image log is heterogeneous and more conductive. Intervals of well-bedded limestone (A), bioherm debris (B), and corals towards to top of the section (C) can be observed. This supports the general shallowing upward trend towards the end of the Upper Jurassic and also supports the seismic facies interpretation
