Abstract
An integrated fault characterization study was performed as part of a comprehensive mature field redevelopment project in the Austrian Flysch reservoirs. Structural interpretation was challenging due to the complexity of the faulting and the poor quality of the available seismic data. Structural complexity is often a reason to degrade the seismic image. The seismic was reprocessed with CRS for noise reduction and CBM as an imaging method. In a close cooperation between geophysicists and interpreters seismic fault attributes were derived. The heavily faulted structure was interpreted in an inductive manner based on numerous fault crossing in the wells and the observed faults on the seismic. An structural was developed honoring all available data leading to an improvement of the geological concept of regional tectonics. Further a number of prospective yet undrilled compartments could be identified in this mature field.
