Oil concentration in produced water
Produced water salinity is typically greater than seawater with NaCl as the predominant salt [2]. The oil component of this water can be more than 500 mg/L [2, 3] and discharge standards for produced water to ocean are typically in the range of 10-40 mg/L of total oil [4]. Produced Water Volumes and Management Practices in 2012 Page 38 California was 2nd in water production, 4th in oil production, and not in the top ten for gas production. Oklahoma was 3rd in water production, 6th in oil production, and 6th in gas production. Produced Water. •Any water that is produced to the surface along with oil or gas •It is the largest waste stream generated by the oil and gas industry. Produced Water Quantity. •On average, about 7 - 10 barrels (bbls), (which is 280 - 400 U.S. gallons) of produced water generated per barrel of crude oil. The produced water, leaving the three-phase separator which separates oil, gas and water coming from the wellhead, is sent to the gravity separator (API separator), which removes, from water surface, oils and other light fractions with a lower density than water. These fractions, removed by an oil skimmer, While any industry that discharges produced water needs to test for oil in water, their specific needs can differ from industry to Techniques for Measuring Oil in Water. WHITE PAPER. Techniques for Measuring Oil in Water | 2 cm-1 is correlated to a concentration value.

The high oil content of this effluent prevents its disposal or reuse. Th…

Typical oilfield produced water contains heavy metals in varied concentrations, depending on the formation geology and the age of oil well [ 5, 20 ]. Heavy metal concentrations in produced water are usually higher than those of receiving water (for enhanced oil recovery) and those found in sea water [ 19 ].
Understanding the physical properties of the formation water that will be produced along with the oil or gas is important to a proper assessment of reserves volumes, producibility, economics, and surface facilities. As a rule, it is best to have reliable laboratory measurements of the physical properties of oilfield waters. The amount of produced water, and the contaminants and their concentrations present in produced water usually vary significantly over the lifetime of a field. Early on, the water generation rate can be a very small fraction of the oil production rate, but it can increase with time to tens of times the rate of oil produced. The produced water, leaving the three-phase separator which separates oil, gas and water coming from the wellhead, is sent to the gravity separator (API separator), which removes, from water surface, oils and other light fractions with a lower density than water. These fractions, removed by an oil skimmer, Typical oilfield produced water contains heavy metals in varied concentrations, depending on the formation geology and the age of oil well [ 5, 20 ]. Heavy metal concentrations in produced water are usually higher than those of receiving water (for enhanced oil recovery) and those found in sea water [ 19 ]. Produced water is by far the largest volume byproduct stream associated with oil and gas exploration and production. Approximately 21 billion bbl (barrels; 1 bbl = 42 U.S. gallons) of produced water are generated each year in the United States from about 900,000 wells. This is equivalent to a volume of 2.4 billion gallons per day. Produced water salinity is typically greater than seawater with NaCl as the predominant salt [2]. The oil component of this water can be more than 500 mg/L [2, 3] and discharge standards for produced water to ocean are typically in the range of 10-40 mg/L of total oil [4]. Produced Water Volumes and Management Practices in 2012 Page 38 California was 2nd in water production, 4th in oil production, and not in the top ten for gas production. Oklahoma was 3rd in water production, 6th in oil production, and 6th in gas production.

13 Nov 2017 You can't produce oil without water, because water is present of oil from offshore platforms to a daily maximum concentration of 42 mg/l.
Oil fields in the Liaohe area produce a significant amount of heavy oil. Current oil production capacity is 8 million tons/year (143,000 bo/d). Production includes steam stimulation and is complicated by increasing water cut. Current water production is 15 million tons/year (260,000 bw/d), Salt concentration of produced water may vary from a few parts per million (ppm) to about 300,000 mg/L,, 1000–250,000 mg/L. Sulfate concentration in produced water is lower than seawater. In some sites that use seawater for oil enhancing recovery, sulfate concentration is high. 1.4.2.2.
Produced water may also contain other toxic components, such as barium, and elevated concentrations of naturally occurring radioactive elements, such as 22 Jan 2013 REACH and research groups and forums for offshore oil and gas. risk-based approach ( RBA ) for the management of produced water OSPAR RBA Predicted No Effect Concentrations ( PNECs ) Background Document. 6 days ago Produced water, which may contain high concentrations of salts and other contamiants, is often stored in pits or disposed of in evaporation
