In Canada, chemical flooding is currently being applied to increase recovery from a number of medium to heavy oil pools in southeast Alberta, southwest Saskatchewan and in the Lloydminster region. In cEOR operations, chemicals are injected into wells to increase oil recovery, but different reservoir operating conditions (e.g. pH, temperature, salinity and presence of alkali and/or surfactant) affect polymer structure and size. Changes in polymer structure or size ultimately compromise the incremental oil recovery performance, project economics, and also contribute to difficulties in its accurate detection and characterization in back produced water (and therefore its optimal reuse).

在加拿大，化学驱目前正在应用于阿尔伯塔省东南部、萨斯喀彻温省西南部和劳埃德明斯特地区的一些中稠油油藏，以提高采收率。在cEOR作业中，将化学物质注入井中以提高采收率，但不同的油藏作业条件（例如pH、温度、盐度、碱和/或表面活性剂的存在）会影响聚合物的结构和尺寸。聚合物结构或尺寸的变化最终会影响到采收率的提高、项目的经济效益，也会给后采出水中聚合物的准确检测和表征带来困难（因此也会影响到聚合物的最佳再利用）。
