PRODUCED WATER TREATMENT CASE STUDIES AND WHITE PAPERS

Capacitance Level Switches Provide Reliable Water/Oil Interface Detection

There are a number of point level approaches to measuring the interface between water and oil for water dump control in the oil and gas industry. However, each has disadvantages — manual methods introduce human error, conductivity switches are rendered inaccurate by buildup, and float switches are susceptible to wear and tear. This white paper introduces capacitance level switches as an accurate and reliable alternative for water/oil interface detection.

    How To Fix High pH And Comply With The Clean Water Act

    When the Clean Water Act was enacted, one of the intentions of this legislation was to reduce the untreated industrial waste water burden on publically owned waste water treatment plants (POTW) so that industrial wastewater would only load the treatment plant to the same extent as ordinary household sanitary waste. Industrial facilities that generated process wastewater had to begin pre-treatment of the water before it could be returned to the local POTW.

    Resolving High PH For Mining Operations

    For an open-pit taconite mining operation in Minnesota, high pH groundwater required round-the-clock pumping to comply with discharge permit limits. After management installed a control system to neutralize the pH, the treated water leaving the site now meets permit limits. Read this case study to learn more about the installed system and results.

Eco-Tec is a globally recognized provider of produced-water treatment systems for heavy-oil operations, featuring advanced micro-media filtration (Spectrum™) and ion-exchange softeners (RecoPur®) that dramatically reduce materials, waste, and operational costs for clients.

PetroSorb™ Activated Carbon

PetroSorb™ Activated Carbon

As refinery operations are forced to generate more product output from marginal raw material sources with aging equipment, the requirement to maintain an acceptable quality of processing chemicals becomes more difficult. Activated carbon used in a fixed bed can continuously treat process chemicals, either in full or in a partial treatment stream to restore their properties in line with virgin product. This greatly enhances the economy of the production process and permits the conversion of more heavily contaminated resources that were previously difficult to exploit.

RIO M Series Spec Sheet

The RIO M Series produces Mixed Oxidant Solution (MOS) chemistry for water disinfection and is systematically optimized for ease of use, reliability, and performance. The RIO is modular which means MOS disinfection chemistry output can be easily expanded 5X without increasing the footprint – just add more cells to the cabinet! Leading the industry in salt and energy conversion, the RIO can ensure the lowest life-cycle cost for your facility.

PRODUCED WATER TREATMENT

“Produced water” is the oil and gas industry term for any water that comes out of the oil or gas reservoir as part of the production process. Oil reservoirs often contain large volumes of water, while gas reservoirs typically have smaller quantities. Sources of produced water include:

  •   Connate water present in the reservoir prior to production
  •   Condensed water from produced gas
  •    Injected water derived from injection wells

The physical and chemical properties of produced water are not consistent. Variation depends on factors such as reservoir geology, hydrocarbon composition, geographical location, and water injection history.
Produced water contains contaminants that require removal before proper disposal or reuse. Some of the impurities or substances likely to be found in produced water include: oil, naturally occurring radioactive materials (NORM), waxes, greases, sand, scales, dissolved salts, CO2 (carbon dioxide) and H2S (hydrogen sulfide) gases, hydrocarbons, production chemicals, and various metals.

The treatment of produced water will differ according to the intended disposal method or reuse purpose. Filtration, cyclonic separation, flotation, and evaporation are among the commonly used treatment techniques.
Post-treatment, there are a number of options available for disposal or reuse, each of which will have different water treatment criteria associated with it:

  • Surface disposal into the sea or into evaporation ponds, subject to local environmental regulations
  • Injection into a disposal well, either a watered out part of the reservoir or to a disposal formation
  • Reinjection for pressure maintenance, replacing sea/aquifer/river water as the source of water injection
  • Reuse for irrigation or as industrial process water

Due to increasing environmental awareness and regulations, disposal to surface waters and evaporation ponds is becoming less prevalent.  Produced water is considered an industrial waste, subject to standards defined and issued by the U.S. Environmental Protection Agency.
