Lab tests show that new process works as an alternative to liquid chemical scale inhibitors
Ecosphere Technologies Inc., a diversified water engineering and environmental services company, announced that its majority-owned subsidiary, Ecosphere Energy Services LLC (EES), completed tests on Ecosphere Ozonix, a technology that treats produced waters and eliminate scaling. The tests confirm that this chemical-free process eliminates scaling in 10,000 and 150,000 parts-per-million (ppm) total dissolved solids (TDS) produced waters. The tests included raw and untreated 150,000 ppm TDS produced fluid from the Woodford shale and raw and untreated 10,000 ppm flowback fluid from the Fayetteville shale.
Test results showed that the untreated produced water samples scaled, while the samples treated by the Ozonix process did not. The dynamic tube blocking tests were conducted by Weatherford Labs in Houston, Texas, to determine the effect the Ozonix process has on scaling. Energy companies currently use liquid chemical scale inhibitors during the fracturing of the well to eliminate scale buildup. The results of the recent tests confirm that the Ecosphere Ozonix process is a possible alternative to liquid chemical scale inhibitors.
"Ecosphere has treated more than 7 million barrels (294 million gal) of water used in natural gas exploration over the past year,” said Robbie Cathey, chief operating officer of EES. “We have recycled production waters for more than 100 wells, allowing the energy operating companies to reuse an environmental resource and save costs. Our recent efforts are proving that our product is not only an environmentally friendly and cost-effective water management solution, but can help treat a well more efficiently without the use of chemicals."
Ecosphere also announced that the U.S. Patent & Trademark Office issued U.S. Patent No. 7,785,470 to this Ozonix patent for treating industrial wastewaters and potable waters. It is the third patent the company has received this year for Ecosphere Ozonix technologies. The inventors for this patent are company founder and CEO Dennis McGuire and Senior Vice President of Engineering Sanjeev Jakhete, who assigned their rights to Ecosphere.
