Oilfield chemicals are chemical compounds used to enhance the oilfield processes and increase the productivity. The oilfield chemical demands are based on certain factors.
High crude oil production required more oilfield specialty chemicals. If Reservoir of oilfield location is enriched with crude oil, the demand will also increase significantly for more production of crude oil and quality petroleum products. In-depth drilling for crude oil also needs more oilfield chemicals. Government policies also define the requirement for oilfield chemicals on case to case basis. Thus the demand of these chemicals depends on various factors that vary on case to case and location to location bases. The oilfields chemicals are supplied to some of the countries due to high amount of reservoirs are found with them like USA, Russia, Canada, Mexico and China. India is one of the leading countries that manufacture and export the significant amount of market share in the world due to huge chemical resources, cheap labor, good knowledge and technological advanced instruments to produce industry class chemicals to act as oilfield chemical to use in oilfield processes.

World market also shows the positive trend and momentum in this field due to large scope of oil field reservoir and demand. No doubt the world is passing through the global economic crisis and has shown the decreased productivity but still the petroleum products market is showing continuous up trend with favorable situations. Surfactants, demulsifiers, corrosion inhibitors, cosmetic waxes are considerably used in oil and gas industries with various applications.

Many chemical compositions used as surfactants are highly in demand of industrial markets. The surfactant reduce the surface tension of the soluble media and used in emulsification process to excrete out water from oil or oil from water based on the soluble property of the chemical.

Demulsifier act as an emulsion breaker that generates Demulsification process and creates insoluble emulsion to disperse out from the crude oil mixture to make the petroleum product more granular and pure by removing the dissolved soluble elements that not required in the end product.

Corrosion inhibitors are known as corrosion preventer for the oilfield exploring equipments and pipelines that are using for carrying the produced crude oil and processed petroleum products. Corrosion inhibitors inhibit the certain process that is executed by produced gases and liquid during the crude oil production process. Thus oilfield chemicals are highly demanding raw material product for better production in petroleum industry. These specialty chemicals are also used in many other industrial applications. 

Importance of Oilfield Chemicals - Emulsion Breakers, Water and Oil Line Corrosion Inhibitors

Various kinds of chemicals are used in oilfield for better productivity and higher efficiency in the processes. While some are used in operations like oil well drilling and exploration many are employed for maintenance purposes like protecting pipelines and equipment from corrosion. There are two most important oilfield chemicals which play an important role in achieving oilfield efficiency and longevity. They are emulsion breakers (demulsifiers) and corrosion inhibitors.

Oil Line Corrosion Inhibitors

Corrosion inhibitors have important role to play in oilfield industries. The pipelines through which oil is transported or conveyed in oilfield are highly prone to corrosion because of presence of water in it. Water contains oxygen which is main contaminant causing corrosion in oilfield lines. The water and oil line corrosion inhibitors for oilfield are those essential chemicals which function as oxygen scavengers absorbing oxygen present in water oil emulsions being transported through pipeline thereby safeguarding it from the reduction-oxidation reaction which occurs when oxygen reacts with ferrous or non ferrous metals causing corrosion. Therefore oil line corrosion inhibitors are very important to oilfields which can save up the costs, downtime and materials employed for repair and replacement due to corrosion in oilfields.

Oilfield Demulsifiers (Emulsion Breakers)

The oil produced in the oilfield is often associated with significant quantities of water which gets associated with the oil either naturally or through injection during the processes. This water should be separated from the oil because it can impact the properties of the oil and can also cause corrosion in the pipelines. This is the reason why demulsifiers or emulsion breakers are required in oilfield. Emulsion breakers for oilfield are those specialty chemicals which can separate out oil and water from the crude oil water emulsions. They work through a process of crude oil demulsification which cause a density change in emulsion making it easier for separation to occur. Demulsifiers can efficiently elevate crude oil value for export while minimizing the operating or maintenance costs which might be required in case if corrosion takes place.

Demulsifier Manufacturer

Rimpro India is a leading oilfield chemicals and demulsifier manufacturer in India producing a wide range of oilfield demulsifiers for water oil separation in oilfield processes. The manufacturer is a specialist at providing high quality oil and water soluble demulsifiers with medium concentration of surfactants and surfactants for oilfield processes including oil recovery and processing, oil drilling, reservoir injection and surface plant process, oil transportations etc.

Oilfield chemicals such as oxygen scavenger, paraffin dispersant, water coagulant, corrosion inhibitors, biocides & demulsifiers which are of critical importance to the oil & gas industry.

SURFACTANT to lower surface tension

SURFACTANT is a surfactant used to modify surface tension and / or build foam during stimulation operations. SURFACTANT is a perfect blending of Co-Polymer and organic compound dissolved in water. SURFACTANT should be used as 1% - 2% addition to fracturing fluids solution and a positive displacement pump is advised for accurate metering. Further upstream the unit, the better mixing with the emulsion of the Demulsifier is achieved. SURFACTANT can be stored in closed containers away from direct sunlight at ambient temperature. During handling, direct contact with human body is to be avoided. Safety goggles and gloves are recommended for safe handling. The spillage can be handled with dry absorbent like sand, sawdust, etc. On ingestion / eye contact with the product, medical attention should be sought immediately.

Demulsifier - Emulsion Breakers

Demulsifier, or emulsion breaker or crude oil demulsifier are a class of specialty chemicals used to separate emulsions. They are commonly used in the processing of crude oil, which is typically produced along with significant quantities of saline water. This water must be removed from the crude oil prior to refining. If the majority of the water and salt are not removed, significant corrosion problems can occur in the refining process. Commercially available Demulsifier formulations are typically a mixture of two to four different chemistries, in carrier solvent(s) such as xylene, Heavy Aromatic Naptha (HAN), Isopropanol, methanol, 2-ethylhexanol or Diesel. Demulsification is a general term used to describe the separation of water from crude oil. As crude oil is produced from a reservoir it tends to become mixed with either natural formation water or mixed formation and injection water. This produced mixture of crude oil and water is termed an oil and water emulsion. It is critical to topsides process operations that the crude oil is efficiently and quickly separated from the water to allow dry oil to be exported and clean water to be discharged within consent, thus maximizing crude oil value and minimizing operating costs. Demulsifiers are generally injected on a continuous basis upstream of the 1st stage production separator but in certain circumstances they can be injected subsea.

Demulsifier selection is best performed on live crude oil thus the selection process must be performed in the field and is generally performed using the “bottle test” method. Using this method numerous base chemicals can be tested on fresh emulsions and at the exact operating conditions thus a product can be formulated which is specific to the field and the emulsion. As field conditions change over its lifetime it is essential to optimize Demulsifier performance on a regular basis.
