Produced Water Beneficial Re-Use – Low TDS Waters

2007, Fossil Water

The study emphasizes the use of existing information sources and the experience of the study team in the evaluation and implementation of alternative approaches to water use. This report focuses on low-TDS produced water with TDS >4,000 mg/l.

Overall, total produced water disposal injection volumes are relatively constant at 265 million m3 per year, representing approximately 720,000 m3/day. The highest disposal volumes are clustered near 18 locations encompassing >80% of the total volumes injected in Alberta. In particular, the largest injection volume clusters are located near Redwater/Fort Saskatchewan, Provost/Hayter, Taber/Grand Forks and Bellshill Lake (Alliance).

Limited information is available from published and/or industry sources – the results of baseline water quality testing in accordance with EUB Directive 44 are not yet available. Available data highlights that, in general, produced water exceeds quality objectives for domestic, irrigation, livestock and/or aquatic protection. In addition, trace amounts of phenols and/or organics also require treatment prior to acceptance for beneficial use.
