We attempt to correlate a set of surface heaving (or uplift) data, well head pressure and injection rate with microseismic data. This correlation may give a high-confidence indication of fracture development or fault reactivation during injection or production operation. The dataset analysed here is acquired during the CO2 injection in In Salah, Algeria. This attempt is a first trial and done in rather qualitative manner than quantitative. In the current study, we focus only on the data from Well KB502. More advanced and detailed analysis will be required in order to achieve information that is more conclusive. Some preliminary result is presented herein. It is expected that the approach in this study can be applied to monitor production operation (including unconventional resources), not only injection.
