Three papers selected from 2018 SPE ATCE look at the challenges and approaches to the treatment of increasing volumes of produced water. Volatile organic compounds (VOCs) present in crude oil can be released to the atmosphere from storage tanks, waste waters, and equipment leaks. A pilot-scale sequential biotrickling/biofiltration unit was designed and tested for removal of VOCs from a wastewater sump. Models were developed for these wells for future water-production prediction and a spatial analysis was also conducted.
