  • Produced water treatment technologies

    Abstract Produced water is a complex mixture of organic and inorganic compounds and the largest volume of byproduct generated during oil and gas recovery operations. The potential of oilfield produced water to be a source of fresh water for water-stressed oil-producing countries and the increasing environmental concerns in addition to stringent legislations on produced water discharge into ...

  • Water treatment technology for produced water

    Large amounts of produced water are generated during oil and gas production. Produced water, as it is known in the oil industry, is briny fluid trapped in the rock of oil reservoirs. The objective of this study was to test produced waters from a Montana USA oilfield using a mobile station to design a plant to cost efficiently treat the produced water for agricultural irrigation. We used combined ...

  • UV disinfection for enhanced oil recovery and other oilfield applications

    One of the biggest challenges facing oil companies today is how to extract more oil from the discoveries made in the last 40 years. Estimates vary, but approximately 66% of the discovered oil gets left in the ground. The International Energy Agency has estimated that if, in the next 20 years, this figure could be reduced to 50%, then this would increase the world's recoverable oil by 1.2 trillion ...

  • Produced water treatment from a to Zinc - reducing levels of Zinc in a produced water stream

    Problem At vast depths, the ocean floor consists of layers of decaying plant and animal matter, containing chemicals like sulphate and zinc, which has built up over the years. When operators are drilling, the matter is disturbed and the various chemicals are released into the water. Since the mid 1980’s the pace of exploration, production, and development in the deep waters of the Gulf of Mexico ...
