CBM Produced Water Management Tool
Selection of processes for water treatment is a complex task and has to consider many parameters that might change over time, including changes in water quality and quantity and economics. Specifically, treatment of produced water is challenging for technical, geographical, and economic reasons. Produced water quality is widely variable, and water may contain contaminants from diverse groups (e.g., dissolved organic and inorganic matter, suspended solids, oil and grease, and dissolved gasses), all of which may interfere with and compromise different water treatment processes.
Produced water is often generated in remote or isolated gas fields that can at times be inaccessible. This makes it difficult to obtain the necessary energy, supplies (e.g., chemicals, spare parts), and maintenance for treatment systems. It also complicates the transfer and beneficial use of the treated produced water. Above all, the economic implications of the technical, geographic, and environmental restrictions will define the viability of gas-field development.
