  • How is oilfield-produced water treated?
  • Currently, produced water is mainly treated using conventional trains that contain adsorbates, membrane filters, phase separators and cyclones. This paper reviewed the detailed characteristics of oilfield-produced water and the assessment of multiple technologies at primary, secondary, and tertiary treatments stages.
  • What is oilfield produced water (OPW)?
  • Formation water from underground reservoir bearing oil and natural gas is extracted along with the oil and gas from onshore and offshore oilfield wells as shown in Fig. 1. This water is referred to as oilfield produced water (OPW) when brought to the surface.
  • How is produced water treated?
  • Mature and robust technology for produced water treatment and disposal. Treatment is carried out through freezing, thawing and evaporation. Efficient in arid environments with regular subfreezing temperatures ( Sorensen et al., 2002 ).The FTE process requires minimal pre-treatment of produced water.
  • What is oilfield produced water management?
  • Oilfield produced water management The PW management strategies can be categorized into minimization, recycle/reuse, and disposal based on ecological priority . Water minimization approach reduces the PW volumes from its source (injection, and natural formation water zone).
