Methods and additives for reducing fouling in water coolers in Steam Assisted Gravity Drainage systems (SAGD) are described in which an additive comprising a cationic starch, either alone or in combination with a water clarifier compound, is introduced into a SAGD system, wherein a lower amount of the additive is used to achieve the same or better results in reducing fouling in the water coolers as compared to an otherwise identical method absent the additive.

Cationic starch-based additives for reduction of fouling in water coolers in SAGD production systems

The present disclosure is directed to additives comprising modified cationic starches that may be applied to a production fluid at high temperatures, such as temperatures ranging from about 80&#xb0; C. to about 300&#xb0; C., for separating water from an emulsion in the production fluid.

A process for drying mature fine tailings is provided. A low molecular weight anionic organic polymer is contacted with a tailings stream to flocculate mature fine tailings and enhance dewatering. The tailings stream can contain, for example, water, sand, silt and fines clays produced from a bitumen extraction process for oil sands ore. The process can also involve rigidification of the suspension.
