This study will focus on one of three primary areas of interest in this solicitation, - water management in coalbed methane and gas shales. It will bring together both producers and potential end-users to address the key issues associated with the management and treatment of produced water for beneficial use. The objectives of this study are fourfold:
- Collect data on the quality (composition) and quantities of produced water associated with unconventional gas production (CBM, gas shale) in the Western U.S. This assessment is essential for subsequent investigations regarding its suitability for beneficial use and will guide the research team and future users in selecting appropriate processes for water treatment and beneficial use applications.
- Explore the most appropriate and cost-efficient technologies for treatment of typical produced waters that will allow beneficial reuse of the treated water. Potential combinations of treatment processes will be selected from both well-established conventional processes that can be deployed in the field today and emerging technologies that show great merit for this application but which are not fully developed yet.
- Assess requirements to minimize environmental impacts and reduce institutional barriers to beneficial use of produced water.
- Compile the findings of the study into an integrative decision analysis framework for management of produced water leading to beneficial use.
The proposed research will develop an Integrated Decision Framework to manage and treat produced water that has the potential to substantially reduce the overall costs and enhance gas recovery and economic viability (and longevity) of CBM and gas shale fields while minimizing potential environmental impacts. The results of this study will provide a technically sound, objective integrated framework to identify, quantify, evaluate and communicate both the extraordinary challenges and opportunities posed by the management of produced water in the arid west. The techniques and methods developed during this study will provide needed guidance to the industry in selecting the most cost-efficient management and treatment strategies for handling produced water by considering the site-specific conditions of CBM and gas shale operations.
Through cost-benefit analyses, this approach will help to promote more cost-efficient treatment technologies resulting in smaller brine volumes, aid in developing strategies to manage and dispose brine streams, and highlight beneficial use scenarios.
