Treatment and Beneficial Use of Produced Water in the western U.S.
Project ID: 3259
Principal Investigator: Katharine Dahm
Research Topic: Desalination and Water Treatment
Priority Area Assignments: 2011 (Advanced Water Treatment), 2012 (Advanced Water Treatment)
Funded Fiscal Years: 2011 and 2012
In many areas of the western U.S., produced water from oil and gas operations can serve as a drought-proof, new water supply, relieving the stress on conventional water supplies. This project will address the following research questions:
What constituents present in produced water prohibit the use of this water for beneficial uses such as streamflow augmentation, irrigation, livestock watering, and municipal and industrial use?
Can a produced water management model using operations research techniques be developed to identify cost-efficient produced water projects?
Need and Benefit
Water exists naturally in subsurface formation along with oil and gas. During the oil and gas extraction process, on average, large quantities of water, referred to as produced water, are generated. Estimates for the volume of water extracted are roughly 5 billion gallons per day from onshore U.S. operations. Produced water is considered a waste byproduct by the oil and gas industry. Generally, the produced water is either injected back into the formation to wash out more oil or discharged to the surface where it causes environmental problems. However, in many cases, especially in the Rocky Mountain region, oil and gas production occurs in areas where there is a need for additional water supplies. If treated to appropriate standards or managed properly, produced water could serve as a "new" water supply and reduce the cost and environmental impact of energy production.
This work combines Geographic Information System (GIS) mapping of produced water occurrence and potential beneficial uses of produced water to identify a practical produced water project that results in an increased water supply for the western U.S. This work also considers the geographic distribution of water quality in terms of the water quality requirements for different types of beneficial use, including irrigation and livestock watering, streamflow augmentation, and municipal and industrial applications.
