Just over a year after Boston-based Gradiant commissioned its first commercial treatment facility for Pioneer Natural Resources, the company announced that it has expanded the system, increasing its produced water treatment plant capacity to 12,000 bbl/d. Immediately on the heels of that announcement, the company told WDR that it has completed a second 12,000 bbl/d produced water treatment facility for another exploration and production company, also in the Midland, Texas, area.

Both plants treat produced water from oilfield operations in the Permian Basin’s Spraberry/Wolfcamp shale formation, using Gradiant’s hybrid Selective Chemical Extraction (SCETM) and Carrier Gas Extraction (CGETM) processes. Anurag Bajpayee, Gradiant’s CEO, explained that SCE is an ion-specific treatment process that is customizable to meet a client’s effluent quality requirements.

plant“In addition to recovering any oil that remains in the water delivered to our site, we are able to generate various grades of clean brine and fresh water from produced water with a TDS of 120,000 mg/L with minimal operator interference. The two CGE units use our proprietary humidification-dehumidification process to produce distillate with a TDS of less than 100 mg/L. We generate additional revenue by producing 6,000 bbl/d of clean brine and 2,000 bbl/d of 10-pound brine,” he said.
Gradiant CFO Luke Johnson said that the company hosted investor visits to both sites last week, coinciding with Midland’s 20th Annual CO2 EOR Conference Week, adding, “As part of our growth strategy, we will close another funding round by the second quarter of 2015, and we wanted to show our investors the progress that we have made in re-casting Gradiant as a water services company rather than simply a water technology company.

“We now have more than 50 employees, and expect to more than double that number by the end of 2015. We’re now looking to increase both our technical and commercial staff…but first, we have to hire a vice president of talent acquisition.”
