Induced Seismicity - Past, Present and Future

Workshop 16: Friday, 7 June
Lecture Room:3
Conveners: Bernard Dost (KNMI)
Mirko van der Baan (University of Alberta)
Ewoud van Dedem (Shell)
William Ellsworth (Stanford University)
Leo Eisner (Seismik)
James Verdon (University of Bristol)

Description:

Mitigation of induced and triggered seismicity, caused by a broad range of industrial activities and felt by local population, is of increasing interest worldwide. Regulators may stipulate long term monitoring of seismicity to gain insight in the parameters that are of importance to the earthquake rupture process. This leads to a large volume of continuous seismic data and many detailed geomechanical and/or seismological studies. The workshop is intended to discuss developments in monitoring, modelling, and mitigation, covering a broad range of applications, including gas production and storage, geothermal projects, hydraulic fracturing treatments, salt-water disposal and mining projects.

Topics and addressed questions:

  • Monitoring (when, how)The role of geomechanics for understanding rock deformation and forecasting
  • Case histories: lessons learnt
  • Identification and management of challenges
  • Mitigation procedures, including effectiveness of traffic light systems
  • Public interaction (social licenses to operate)
  • Assessment of seismic hazard and risk
Workshop format:

  • One day workshop
  • Presentations followed by discussions
  • Possibly some keynote speakers
Who should attend:

Researchers at universities, governmental or semi-public research institutions, regulators, industry professionals including operators and service providers.
