“…Although the energy release of these events is much smaller than the signals expected for a complete parting of the casing, the events could be a result of deformation of the wellbore completion associated with the thermal expansion of the metal liner. It is interesting to note that these same signal characteristics are used to automatically detect casing-failure events at Cold Lake, Alberta (Smith et al 2006). However, at Cold Lake, the complete casing failure was caused by the tensile parting of the casing joint, resulting in a substantially more energetic signal.…”

“…Previous studies have reported microseismic activity (Maxwell et al 2003;Smith et al 2006;McGillivray 2004) and surface deformations for cyclic steam injections (Davis et al 2000). SAGD typically uses lower injection pressures and rates compared to CSS (Collins 2002), and results in less seismic and surface deformation.…”

“…Monitoring the steam chamber growth is critical to optimize the heavy oil recovery, confine the stimulation to the reservoir and identify bypassed regions. In some fields, this geomechanical deformation also leads to casing deformations and well integrity problems which may result in operational problems 5,6 . This geomechanical deformation may be expressed through seismic deformation and the release of seismic energy as fractures adjust to the strain field 4 , and also may result in surface expansion or subsidence 5 .…”
