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