Flowback and produced water is the largest waste stream generated in oil and gas industries. While there is public awareness over wastewater produced during shale gas development, similar technological advances in multiâ€stage hydraulic fracturing are the primary mechanisms facilitating tight oil production within low permeability reservoirs throughout the United States as Western Canada Sedimentary Basins.
Many shale gas and petroleum producers are experiencing economic, political and regulatory pressures to find ways to minimize the volume of water they use and to reduce hazardous wastewater discharges. For these reasons, the reuse of flowback and produced water is becoming a viable option to many operators' water management plans.
Hydraulic fracturing is a water-intensive process that has made water management one of the most studied and widely publicized issues in shale production. There are several challenges related to water use in oil production, including:
Reusing flowback and produced water can offset hydraulic fracturing fresh water source requirements while avoiding the cost associated with flowback disposal. In geographic areas where hydraulic fracturing coincides with existing gas and oil production, the opportunity to incorporate wastewater reuse may further reduce industry's reliance on fresh source waters for hydraulic fracturing. Petroleum and gas wastewater is conventionally treated by using different biological, chemical and physical methods.
However, in addition to constituents injected into the formation during hydraulic fracturing - flowback and produced water includes minerals and organic constituents from the formation that dissolve into the fracturing water. This creates a brine solution that includes high concentrations of salts, metals, oils, greases, suspended solids and soluble organic compounds, both volatile and semi-volatile that vary over time. Therefore, the degree and treatment required to facilitate water reuse is poorly defined by the difference between the quality of the initial flowback and/or produced waters in comparison to the desired hydraulic fracturing source water specifications. Due to such reasons, major research efforts could, in the future, focus on optimizing current technologies, as well as use combined physico-chemical and/or biological treatment of produced water in order to comply with reuse and discharge limits.
This webinar by expert speaker Dr. Barry Stevens provides insight into the technologies, challenges, risks and rewards of reusing flowback and produced water from oil and gas production. It also focuses on the optimization of current technologies and use of combined physico-chemical and/or biological treatment of produced water in order to comply with reuse and discharge limits.
