Summary:
The performance of heavy-oil production by Steam-Assisted Gravity Drainage process (SAGD) can be
affected by near-well reservoir heterogeneities. However, as many factors interact during thermal
production such as changes in oil viscosity, fluid saturations, pore pressure, stresses,... the interpretation of
4D seismic data in terms of steam chamber geometry is not direct nor unique.
