Cost-Saving Predictive Modelling Tools For Oilfield Water Managers
Significant water volumes are used in oil and gas production activities in Canada and globally. With the continuous decrease in freshwater volume and quality, producers are under pressure to reuse oilfield produced water in order to decrease freshwater consumption and reduce disposal volumes. In addition to promoting sustainability, these practices provide an economic advantage for many producers in Alberta and BC.
However, the presence of contaminants in oilfield produced water, such as free oil, suspended solids, iron, hydrogen sulfide, polymers, hardness and many others can pose challenges in reuse, disposal, storage or discharge applications of this water. As a result, various water treatment technologies are now used to mitigate contaminants in order to comply with legislation, minimize safety risks, and optimize operations.
In this domain, chemical modelling and databases serve as time-saving and cost-effective predictive tools for reliable prediction of cost and efficiency of water treatment and handling systems.
