Beyond the Dots - Microseismic Monitoring of a Fractured Reservoir During Steam Injection in Oman

A Microseismic network of 13 wells over a fractured heavy oilfield in Oman has accurately monitored a steam injection program and has also observed sufficient multi-well events to enable extensive SMTI analyses. The SMTI data has been analysed together with the steam injection progress to identify the source mechanisms and fracture planes in relation to the pre-existing fault network, and has indicated, in different areas, both re-activation of existing faults and new fracture activity.
