SAGD technology will produce 40,000 barrels of bitumen per day for Canadian oilfield
Veolia Water Solutions & Technologies has been awarded the supply of a Steam Assisted Gravity Drainage (SAGD) produced water evaporator system for one of the largest heavy oil producers in Canada.
The SAGD technology will be used to produce 40,000 barrels of bitumen per calendar day for the oilfield located in Northern Alberta. The resulting produced water from production, after de-oiling, will be further treated with the HPD evaporator technology from Veolia. Clean distillate from the HPD evaporators will provide boiler feed water to the steam generation system.
The patented Silica Sorption process will be utilized as a solution to reduce chemical consumption as well as provide flexible disposal options of the resulting evaporator blowdown by operating at a lower pH level. The process minimizes fouling of the heat transfer surfaces by causing silica to adsorb on Silica Sorption seed crystals rather than precipitating on heat transfer surfaces. In addition, this provides robustness against hardness and oil & grease spikes in the produced water.
The HPD evaporator system is designed as a fully modular system, including all major process and ancillary equipment. This greatly reduces field installation time as well as the associated costs and complexity during construction at this new well site.
