Different technology options for monitoring oil in produced water – inline continuous monitoring and IR analysis
No offshore facility wants to be caught with a sheen around their platform as that can result in a costly fine for exceeding discharge permit limits for oil. Onboard oil in water analyzers are necessary to ensure the oil/water separation systems are functioning properly before overboard disposal of the produced water. Bench top analyzers have traditionally been used to test oil in water although ...

Solvent-free oil-in-water analysis
Non-ionic surfactants can homogenize oily, produced water samples, creating optically clear microemulsions that are ideal for fluorescence measurements [1]. The use of surfactants to reduce fouling and improve the performance of on-line, fluorescence-based, oil-in-water monitors has been reported previously [2,3]. This paper describes the use of surfactants to prepare discrete water samples ...

Monitoring heat exchanger leaks in Paper plant - Case Study
The Situation A paper plant in the Eastern United States uses 500 gallons per minute filtered pond water for cooling lubricating oil in its paper line. The resulting warmed water is diverted to an onsite pond. Because the water is used to cool lubricating oil, the plant could not reuse the water in its pulping process for fears of possible oil contamination of the paper pulp. The Problem The ...

Advanced Treatment of Produced Water for Crop Irrigation - Case Study
The Situation California is currently facing one of the most severe droughts in recorded history. In order to mitigate the drought conditions, various water conservation measures have already been implemented, and others are being considered. One method under consideration is using the advanced treatment of produced water to make it available for irrigation. A major challenge to the success of ...

Emulsion breaking techniques for oil in water solvent extractions
Certain types of samples, such as those containing detergent, may form emulsions when doing an oil in water extraction into a solvent. The boundary between the solvent and the sample will have an emulsion layer that has a cloudy or milky appearance as shown in this photo. According to U.S. EPA Method 1664, “if the emulsion is greater than one-third the volume of the solvent layer, the ...

Validation of Salt Water Disposal Well Treatment Plants with Handheld Oil in Water Sample Analyzer
Salt Water Disposal (SWD) well operators often dispose a substantial volume of oil inadvertently when injecting salt water, thereby losing the opportunity to sell the oil on the market and potentially reducing the ability to inject water in the well. Injection facilities are typically operated with minimal instrumentation or system optimization, which means the operators don't know how much, or ...

Matching oil in water analyses with regulatory methods
While the amount of oil in water is highly regulated, it can also be a challenging measurement. It is complicated by the fact that oil conies in many forms and the measurement is defined by the particular regulatory method. When EPA 1664 is the regulatory method, the "oil" is anything that is extracted into hexane and remains after the hcxanc has been evaporated and appears as weight. In regions ...

Steam-Assisted Gravity Drainage
Steam-assisted gravity drainage (SAGD) was first developed to recover bitumen from the Alberta’s Canadian oil sands. Bitumen is an especially heavy, tar-like hydrocarbon known for its adhesive qualities. The principal idea behind SAGD is that two parallel horizontal wells are drilled through a reservoir, one above the other. The top well is used for injecting hot steam into the oil sands. ...

Matching Oil in Water Analyses with Regulatory Methods - Case study
When analyzing oil and grease in water while out in the field, it is important to use an EPA approved method and equipment. While the amount of oil in water is highly regulated, it can also be a challenging measurement. It is complicated by the fact that oil conies in many forms and the measurement is defined by the particular regulatory method. When EPA 1664 is the regulatory method, the "oil" ...

What is Produced Water?
Produced water is a byproduct brought to the surface during oil and gas exploration and production. Sometimes it is called formation water, brine, or saltwater. It is typically brackish and comes from underground formations, either from zones adjacent to the oil and gas, or from the same zone as the hydrocarbons. In some oil and gas operations, the produced water results from injecting clean ...

Quantifying the concentration of crude oil microdroplets in oil–water preparations
Dissolved constituents of crude oil, particularly polycyclic aromatic hydrocarbons (PAHs), can contribute substantially to the toxicity of aquatic organisms. Measured aqueous concentrations of high–molecular weight PAHs (e.g., chrysenes, benzo[a]pyrene) as well as long‐chain aliphatic hydrocarbons can exceed the theoretical solubility of these sparingly soluble compounds. This is attributed to ...

Monitoring hydrocarbons in Bilge water - Case study
The Situation Various processes onboard ships, such as machinery wash-down, maintenance, and leakage, generate oily wastewater. This contaminated water flow collects in the bilge of the ship. Marine diesel, lubricating oils, grease, as well as other contaminants may be present in bilge water. The bilge water is discharged overboard, with oil and grease concentrations in the discharged water ...

Comply with Highly Regulated Oil in Water Measurements Using Portable Infrared Analyzers
The Petroleum Industry – both offshore and onshore -- has regulations that limit the amount of oil in discharged water. Fixed filter infrared (IR) analyzers have been used to test oil levels in produced water on drilling platforms for over 45 years for a number of reasons. On oil rigs where real estate is at a premium, infrared analyzers such as the Wilks InfraCal TOG/TPH Analyzers are ...

Oil in Water Monitoring using Handheld UVF-500D Analyzer - Case Study
Decommisioning Offshore Oil Platforms in California Coal Oil Point in Santa Barbara, CA is a popular spot for surfers (above), with Platform Holly looming in the distance. This and a network of other oil platforms were permanently closed down after the 2015 pipeline spill at Refugio State Beach A contractor is using the UVF-500D to test oil in water on-site for plugging and abandonment ...
