A common quality specification for produced water recycling
PWS board member Morris Hoagland discusses the benefits of adopting a clean brine common quality specification, an initiative which he will present during a webinar later this week.
The industry has clearly demonstrated that produced water can effectively be recycled into new hydraulic fracturing completions in the US’ Marcellus and Utica shale plays, but the adoption of this practice has been slow in other shale plays where produced water disposal costs are relatively low. Advances in produced water treatment and the increasing scale of treatment operations have together reduced recycling costs over the past few years so that recycling produced water is now often cheaper than buying new water and disposing produced water.
Now that the economics of recycling have become more favorable, there is a need for common quality parameters to make it easier for companies to trade treated produced water, known as “clean brine”. A common quality specification would further optimize water management costs and help the industry recycle more water while reducing pressure on the freshwater resources needed by farmers, ranchers, municipalities and broader industry.
The Produced Water Society (PWS), which is the world’s largest association of oilfield water professionals, has initiated this project in the interest of bringing water management best practices to the oilfield. The common specification that we are proposing reflects a general consensus among three dozen oilfield water professionals from whom we have received input. I will be presenting PWS’ proposed common specification during a webinar on Wednesday, August 12th at 10am CDT. You can register here to join the presentation.
