Workshop 17

Fault and Top Seal Essentials

Date: Sunday 4 June 2023


  • David Misch (Montanuniversitaet Leoben)
  • Andras Zamolyi (OMV E&P)



Top and fault seal assessment will play a pivotal role not only in the development of new oil and gas prospects in mature hydrocarbon provinces, but also in numerous emerging low carbon geoenergy and subsurface storage applications such as hydrogen storage, CO2 sequestration, geothermal energy recovery, etc. This workshop aims at providing a broad overview of fault and top seal research trends in industry and academia and facilitating a discussion about future development needs based on keynotes and invited talks delivered by leading experts in the field. These will be selected based on cornerstone presentations and contributions of the latest major events and key journal publications, complemented by experience sharing from practical examples of the industry. The workshop should be highly interactive, and topics should be developed along the way based on the input of the speakers and participants.


Participant Profile

Participants from the hydrocarbon, subsurface storage and geothermal industries, related consulting businesses, and academia (universities, research institutions).
Researchers/experts at all levels.
Keynotes and invited speakers will be senior experts in the field.
