Steam-assisted gravity drainage (SAGD) has become a method of choice for in-situ production of bitumen for oil sands projects in Alberta, Canada. Fluid production using SAGD results in the formation of a high water cut complex emulsion requiring the use of both reverse emulsion breakers and emulsion breakers in order to produce saleable oil to the pipeline and clean water for reuse or steam generation. As a facility grows and adds more well pairs to the system, maintaining the water quality from the separation vessels becomes increasingly important to growing the daily bitumen production. The enclosed paper will detail the development of a new solution polymer designed to treat the produced complex emulsion. Through an improved synergy with the demulsifier, the newly developed reverse emulsion breaker reduced the required levels of demulsifier to treat the fluids while maintaining or improving the system water qualities observed.
