In oil production today, water is an inevitable byproduct. In fact, nearly 90% of crude contains oil and water emulsions. The gradual encroachment of water into oil-bearing formations and the advent of secondary and tertiary recovery methods has led to the development of new technologies to break crude oil and water emulsions.
Petroleum demulsifier is recommended to break oil field oil/water emulsions and aid in solids removal from liquids providing a high quality produced crude and clean effluent water. These emulsion breakers work by attacking the droplet interface causing the droplets to disperse or gather into larger droplets. This demulsification action causes a density change making it easier for separation to occur. Factors that influence the type of emulsion breaker selected include the type of emulsion, either oil-in-water or water-in-oil, and the API gravity of the crude. Evaluation of the rate of water drop, sharpness of oil/water interface, and cleanliness of the water are included in analyzing for the proper oilfield emulsion breaker.
The need for oilfield chemical demulsifiers is seen in almost every industry segment; anywhere oil and water are used. We provide this chemical to major users of petroleum emulsion breaker for demulsification include the following industries: chemical processing, petroleum refineries, fuel washing prior to gas turbines, slop and tramp oil treatment, and importantly in the processing of crude oil in the oil field, both to treat synthetic mud’s and to treat the produced hydrocarbons.
PETROFANN  Demulsifiers, or emulsion breakers, are highly effective in removing water from water-in-oil emulsions to provide dry, on-specification oil. Formulations made with our expertise can improve separation rate, allow a smaller footprint and help increase capacity for existing separator units.
Advantages:

• Quickly reduce water-in-oil to levels of 0.1 to 0.5 percent
• Provide sharper interface between the two phases for easier separation
• Remove more water to get closer to commercial crude oil specifications
• Deliver high performance in heavy oil, addressing problems arising from high viscosity
• Highly efficient at low temperatures, reducing he expense needed to heat oil
• Reduce oil-in-water levels for easier discharge or reinjection of water

 Packaging and Handling:
PETROFANN  demulsifier is packaged in 55 gal. Steel drums. (208 liters) It contains an aromatic solvent, and should be handled easily semi-skilled workers.

The production of gas and oil is often accompanied by water, either from the formation, from condensation, or from water injected as lift assist. Acid gases, such as hydrogen sulfide (H2S) and carbon dioxide (CO2) are often present in produced fluids, and oxygen is sometimes a contaminant in the water used for injection. These acid gases increase the corrosively of the waters to steel, and can significantly impact the safe operating life of production tubular and equipment, production vessels, and transportation systems.

The control of corrosion in the oilfield can be a complex problem, requiring detailed analysis and a thorough understanding of the range of conditions expected during the life of the system prior to the development of a corrosion management plan. PETROFANN  corrosion inhibitor product line consists of a number of formulations – some have been developed to address specific corrosion problems and others have been formulated to have wide applicability. PETROFANN  products are proven performers with a solid history of “raising the bar” in providing cost-effective corrosion protection in all oilfield operations. Applications include controlling corrosion in all types of oilfield operations, including oil and gas production, processing, and transportation systems.

Corrosion inhibitors react with the metal surface to form an impermeable film layer on it to stop galvanic corrosion through the reactions of produced oilfield materials and exploring equipments as well transporting pipe network. The organic base or aqueous form work well in high-low temperatures or any kind of environments helps to improve the performance and efficiency of oilfield machineries with decreased down time. These specialty chemicals are the best practices to reduce the detrimental corrosion effects on oilfield plants and exploration-carrying devices.

Amine based inhibitors act by forming a persistent film on the drill hole piping and general oil handling equipments such as tanks and inhibits corrosion resulting from hydrogen sulfide and organic acids in the oil field. Organophosphate inhibitors are water soluble formulations used for general prevention of corrosion on metal surfaces. They are particularly effective in preventing corrosion resulting from the oxidation process of oxygen. This type can be added to agitating muds of the oil wells for protection of the equipment. Organic inhibitors are formulated to function under high temperature and high pressure gas and oil production machines.

PETROFANN scale inhibitors mitigate and prevent scale formation in wellbores, pipes and associated equipment, improving oil and gas flow.

Scale is produced by water precipitation which occurs when producing crude oils or injecting water, and occurs under certain temperatures, pressures and fluid dynamics. Scale deposition in production equipment is a major cause of operational problems such as flow restriction, decreased production and deferred and lost oil. We support oil producers around the world to mitigate any risk associated with inorganic scale deposition, both in topside and downhole operations. Our team of experts can assess each situation and provide solutions to maximize production and up-time in a scaling environment.

Our innovative technologies provide real-time scale monitoring and a unique delivery system that controls depositions, corrosion and reservoir souring by delivering inhibitors to the problem immediately.

Biocides and treatment formulations control bacteria populations in drilling, completion, production, processing and transportation operations.
Biocides applications address many significant safety, equipment and regulatory/contractual issues resulting from bacteria growth and the production of biogenic (bacterially-generated) hydrogen sulfide, including:

• Reservoir fouling
• Production equipment plugging and corrosion
• Heat exchange equipment corrosion and fouling
• Water disposal and water flood system corrosion and permeability damage
• Pipeline and storage tank corrosion and product deterioration

In mitigating these problems, PETROFANN products improve profitability and safety by:

• Increasing production capacity
• Reducing the need for costly well interventions
• Lowering costs for piping and equipment maintenance
• Reducing use of hydrogen sulfide scavengers to control biogenic H2S levels

Bacteria Control Support
To ensure the most effective facility design and remediation treatments, PETROFANN expert evaluations help to determine the most appropriate product, application technology and monitoring system.
PETROFANN works with customer engineering and operational personnel during project design, construction and commissioning to help determine the potential for bacterial contamination.
To minimize problems associated with operating previously fouled systems, we recommend procedures and processes to minimize the risk of contamination. PETROFANN experts are highly experienced in the design and implementation of prevention, remediation and maintenance programs

PETROFANN antifoam is particularly useful in controlling foam conditions caused by contamination from liquid hydrocarbons, particulates, or surfactants in general. Both refinery and natural gas processing facilities often encounter these types of contamination
Gas in produced crudes can cause foaming under several different conditions. For example:

1. When crude oil is being pumped through a heat exchanger, it undergoes turbulence. The light ends vaporize sooner than the heavier fractions. In the attempt of these vapors to escape before they can overcome the natural viscosity of the heavier fractions, foaming can occur. 
2. Water in hydrocarbon under high pressure and temperature can cause severe foaming when released to atmospheric conditions as it tries to escape as a vapor.

Foam reduces the overall capacity of treating equipment and can make the goal of achieving pipeline or saleable oil difficult to obtain. Uncontrolled foam can lead to production tank overflow that translates to lost revenues and extra expenditures for cleanup operations. By maintaining control over foam, dehydration equipment will function more efficiently. Production losses are reduced and the volume of production transported to refineries is increased.
Antifoams are chemicals which, when added to a foaming system, will orient at the surface and break the film that stabilizes the foam. The use of chemical antifoams is the most popular method for foam control and has been used extensively globally. Total cost of operations and ROI are greatly improved by the proper selection of an antifoam program.
