Produced and flowback water treatment and recycle in unconventional gas shale plays has long been one of the largest operating costs for operators. This varies from field to field, depending on freshwater supply, the chemical concentration of flowback and produced water, and environmental regulations. In the current lower gas-price market and with long-term produced water handling, some operators are looking to recycle and reuse produced water for frac-completion operations.
A large, independent oil and gas operator in the Marcellus installed a Select Energy Services/Water Rescue Services (SES/WRS) mobile electrocoagulation treatment and recycle system to support frac-completion operations. Treatment was done at the Shaskas Well Site near Montrose, Pa., to manage water challenges from:
- The significant cost of trucking produced water to water-disposal wells
- The number of producing gas wells that came on line and handling of the increased produced water
- Long-term treatment planning approaches, not including total-dissolved-solids (TDS) reduction
The way to address these concerns was by reusing as much flowback and produced water as possible. Shaskas was identified as a central location for gathering and treating produced water. The SES/WRS treatment and recycle site went into operation in 2012 and continues to provide brine water for completion.
