Abstract
Since the end of the 1990’s, several unconventional hydrocarbon production operations and geological CO2 storage projects have taken place in different countries with various monitoring plans. These plans often include either active or passive seismic monitoring in order to provide feedback on the geomechanical effects of CO2 injection.
In order to realise an effective monitoring plan a baseline must be established – and to date these have been carried out with varying degrees of success using different methods. The goal of this deliverable is therefore:
- Analyze the most pertinent case studies using published documentation to assess the effectiveness of the baseline
- Set up a list of recommendations for future active/passive seismic baselines based on the experience gained from these case studies
This report explores several case studies for different settings: CO2 storage pilots, Enhanced Oil Recovery (EOR) operations, non-conventional hydrocarbon extraction in both onshore and offshore settings.
