EVX Midstream Partners, a Houston-based pipeline operator has completed the first phase of construction of oilfield wastewater gathering system in the Eagle Ford Shale of South Texas. It is touted as the largest wastewater gathering system in South Texas shale play.
"EVX is positioned to be the largest gatherer of produced water in the Eagle Ford basin," CEO Herb Chambers IV said in the statement. "We have recently completed over 300 miles of large diameter water gathering systems and have pipe connected many of our 20-plus saltwater disposal wells to provide our producer customers and trucking companies unprecedented operational flexibility”.
Oilfield wastewater, also known as produced water, is treated to be used again in drilling or hydraulic fracturing operations but most of it is pumped into deep underground reservoirs known as saltwater disposal wells.
The company owns and operates 26 saltwater disposal wells throughout the Eagle Ford Shale that are permitted to inject up to 600,000 barrels of water per day. Produced water was traditionally hauled by 18-wheelers to disposal sites, though the trucks are increasingly replaced by pipelines.
