Produced Water – Beneficial Re-UseProduced Water – Beneficial Re-Use
Fossil Water – PTACuse of existing information sources implementation of alternative approaches to water use. focuses on high-TDS produced water
(in excess of 4,000 mg/l).

Conclusions: beneficial reuse of produced water
requires: Enhanced characterization of produced water
quality Confirmation of treatment technologies Streamlined approval process:
Codes of Practice Monitoring and Enforcement:
standardized approval and reporting practices Economic incentives:
creation of framework to promote re-use and substitution.

A 2020 Fresh Water Neutral A 2020 Fresh Water Neutral Upstream Petroleum IndustryUpstream Petroleum Industry
The study, by Alberta WaterSMART evaluated: The potential for technology and policy to
move the UPI towards a fresh water neutral position by 2020.
Where:Fresh water defined as surface or subsurface
water with a conductivity 4,000 mg/L or less. The basis for neutrality assumes a water
balance between the south and the north.
1515
A 2020 Fresh Water Neutral A 2020 Fresh Water Neutral Upstream Petroleum IndustryUpstream Petroleum Industry
The study identified that: the fresh water demand of conventional
Oil production is dropping. the oilsands are the largest consumer of
fresh water today. the oilsands will consume an even larger
percentage of fresh water in 2020.
1616
A 2020 Fresh Water Neutral A 2020 Fresh Water Neutral Upstream Petroleum IndustryUpstream Petroleum Industry
The water demand forecast in this study assumes that this historical rate of decline will continue until 2020 when the consumption of fresh water will be close to zero.

A 2020 Fresh Water Neutral A 2020 Fresh Water Neutral Upstream Petroleum IndustryUpstream Petroleum Industry
The most significant opportunity in the south of the province: Conventional produced water treatment with such technologies as:
Reverse osmosis, Electro-deionization (EDI), Membrane technologies and Evaporation-crystallization

Oilsands Mining:
enhance water treatment to improve recycle rates reducing dependence on fresh water for cooling accelerate consolidation of the tailings (release water)
Water trapped in tailings accounts for a significant percent of makeup water demand.
Research efforts need to be focused on the water contained within the tailings stream and its recovery.
