Washington, DC - Fifteen research projects aimed at addressing the technical challenges of producing natural gas from shales and tight sands, while simultaneously reducing environmental footprints and risks, have been selected to receive a total of $28 million in funding from the U.S. Department of Energy’s Office of Fossil Energy (FE).
The projects, valued at just over $36.6 million over two years, add to the research portfolio for FE’s Ultra-Deepwater and Unconventional Natural Gas and Other Petroleum Resources Research Program, which develops technologies and strategies to improve the safety and minimize the environmental impacts of oil and natural gas exploration and production.
The projects will address research needs primarily in four categories: (1) reduced environmental impacts, (2) improved water handling and treating methods, (3) enhanced characterization of shales, and (4) improved understanding of the hydraulic fracturing process.
Projects range from testing innovative technologies for cleaning fracture flowback water, to finding new ways to improve casing cement jobs, to increasing the understanding of the relationship between underground water disposal and induced seismicity.
Approximately $8.6 million of the total value of the projects is provided via cost-share by the research partners, in addition to $28 million in federal funds. The research contracts will be administered by the Research Partnership to Secure Energy for America (RPSEA), under the management of FE’s National Energy Technology Laboratory.
