The problem of cold and post-cold production for heavy oil
[Lloydminster type] reservoirs is addressed. First, an overview of cold production related material is presented. The reservoir state is postulated based on behaviour of laboratory systems. Then several experimental methods for additional heavy oil recovery are attempted in the same cold produced laboratory models. The methods tested include water flooding, gas flooding, and polymer flooding. The effect of sand production is evaluated. The results are very preliminary, but encouraging. This work is offered as a challenge for the industry to consider the state of all cold produced heavy oil reservoirs and focus on the possible alternatives for this significant Canadian reserve.
