abstract: Optimizing the performance of the entire Cold Lake system seems to be an impossible task at first. It was therefore decided that solving a scaled-down version of the problem would be more productive, and help understand the full problem better and identify suitable mathematical models.

The first part of the report summarizes the discussions and the models proposed for a four-well problem. Because the models are non-linear, one of their major draw-backs is that they quickly become very computationally expensive, and are impractical for the number of wells at Cold Lake.

The second part of the report discusses a new approach to the problem, where it has been formulated as a linear programming problem, and its size is independent on the number of wells. Results for a test case are presented.
problem_statement: At Cold Lake, Alberta, Imperial Oil uses a cyclic steam simulation process to produce heavy oil from oil sand formations. Oil, water, and gas are produced; the water and gas are recycled into the steam and oil treatment processes. There are 3200 wells still active in their field, so their problem is highly complex. The goal is to optimize the performance of this system, taking into account the interdependencies in the system and that there are varying time delays in the process.
