Despite the fact that the Molasse Basin belongs to the most explored and studied petroleum regions in Europe, manifested by 5000 seismic records and 1000’s of wells, it still holds the one or other surprise, as the Haidach gas field showed in ’97, being the biggest gas discovery (4 bcm) since the start of exploration in that region 1931. New technologies, advances in seismic processing and interpretation helped understanding the geology besides increasing the exploration efficiency and highlighting unknown prospects. Here the Lithothamnium Limestone has an interesting role, being an unconventional play with rather difficult reservoir properties to produce from. The presented here how-to, combining different approaches to achieve the best yield will try to lead the way to a deeper understanding how state-of-the-art production technology can optimize production.
