No natural gas was released at an Arlington, TX, well site on Saturday, when flowback of pressurized water during hydraulic fracturing occurred, city authorities said. A voluntary evacuation of area residents was enacted and, by Sunday afternoon, crews from well control company Boots & Coots had the Vantage Energy-operated well under control. The incident happened at the Lake Arlington Baptist Church site on Little Road. "This was a very serious situation," said Arlington Fire Chief Don Crowson. "To get this incident under control, we worked closely with all city departments, Vantage Energy, Arlington Independent School District, the Red Cross and our faith-based organizations." Arlington is near Dallas-Fort Worth, in the Barnett Shale play.
