I just watched a tape of the latest Flower Mound meeting where the mayor spoke as a citizen. (Click HERE and it’s about 10 minutes in during the public participation) She was challenging Tom Haden about what was in the jars he brought to the last meeting. (He brought two jars, one contained what he called “frack fluid” the other was recycled drilling waste. I don’t know if it was recycled flow back or produced water.)
The mayor said her understanding is that frack fluid is the mixture of chemicals that are injected down the drilling hole. Then she said what comes back is produced water.
Please Mayor, read this: Well plan injects pressure into wastewater dispute
During fracking an undetermined amount, somewhere between 10% and 30% according to some in industry, of the frack fluid comes back up the hole and that is called “flow back.”
Produced water is what industry calls “saltwater” that is in the formation and comes up along with the gas. Produced water may also contain flow back/frack chemicals and hydrocarbons from the formation.
