New Produced Water Blueprint Expected in 2019

New Produced Water Blueprint Expected in 2019
An upcoming report could usher in produced water's transformation from a byproduct to a resource.

According to the Ground Water Protection Council (GWPC), a U.S. association of state ground water regulatory agencies, more than 90 percent of produced water – laden with salts, organics, metals, solids and other constituents – is reinjected into oil and gas reservoirs to enhance production or disposed in porous rock layers.

Given freshwater supply constraints, particularly in drought-prone areas, GWPC members are developing a blueprint that they hope will aid in transforming produced water from a byproduct of upstream oil and gas operations into a resource that could offset freshwater demand both inside and outside the oilfield.

“Let’s use fresh water for drinking and other water for industrial uses,” Dan Yates, GWPC’s associate executive director, said during a panel discussion Monday at the North American Gas Forum (NAGF), an annual event in Washington, D.C., sponsored by Energy Dialogues LLC.

Launched in mid-2017, a multi-stakeholder working group assembled by GWPC is working on a report outlining how policy makers, researchers, regulators and others can address various opportunities and challenges associated with using produced water for beneficial uses. Moreover, the organization contends that finding alternatives to disposing of produced water underground could decrease induced seismicity.

According to Yates, the report will consist of three distinct modules that will:

  • Introduce the regulatory and legal framework for produced water
  • Outline current and potential uses for produced water in the oil and gas industry
  • Examine current and potential uses for produced water outside the oil and gas industry

Yates also noted that the report will identify challenges associated with produced water on several fronts: environmental, regulatory and legal; liability; and public perception. In addition, pointing out that injecting waste water in the ground is typically the most economical approach, he stressed that it will be necessary to make it more advantageous to pursue alternatives such as water recycling.

“It’s going to be increasingly important that midstream water infrastructure continues to grow,” Yates said.

Members of the working group include state oil and gas water quality regulatory officials, industry, environmental nongovernmental organizations, academics and others, GWPC notes in an online summary of the project. The summary acknowledges that a number of barriers currently prevent making produced water “an important part of a state’s water portfolio,” including:

  • Water quality
  • Location
  • Treatment cost
  • Long-term availability
  • Ownership and liability concerns
  • Regulatory constraints

“In addition, some new alternative use proposals for produced water will also require scientific and technical research to better understand potential environmental or health impacts and identify mitigation strategies,” GWPC has stated.

The nonprofit expects to deliver a draft produced water report to its board of directors by the end of first quarter 2019.

It is time that science caught up with fresh water reality. There is plenty of water in the ground, the problem is most of it is “salty”, some of it as much as 30% by volume being “salts”....not just NaCl. Technology exists to remove the salts, however, what does one do with those potential mountains of salts of varying composition. If an economical use can be found for the trace minerals accompanying the NaCl, many of the fresh water issues in the world can be resolved. Oil in the USA was once a contamination of salt water wells that sought bromine salts. Fresh surface water is far too valuable to waste by pumping it into contamination resulting from fracture and/or acid stimulating oil and gas wells as well as simple disposal in another porous strata. Disposal can release rock stress in the form of mild to severe earth quakes as seen in Oklahoma and Texas in recent years. I normally resist economic legislation for environmental purposes, however, putting economic incentives into recycling or even just plain exploiting of produced water has potential of benefiting every inhabitant of this planet.
