Seismic facies and reservoir characteristics of a deep-marine channel belt in the Molasse foreland basin, Puchkirchen Formation, Austria

摘要

Oligocene–Miocene deep-water deposits of the Puchkirchen and basal Hall formations contain the main gas reservoirs of the Austrian Molasse Basin. A new seismostratigraphic model, based on a 2000-km2 (772-mi2), regional, three-dimensional (3-D) seismic data set, has fundamentally changed our understanding of the depositional processes and reservoir distribution in this classic deep-water foreland basin.
