A successful oil and gas production operation is not only determined by the quality or the amount of oil discovered in the reservoir. A well designed process line, and total elimination of impurities and detrimental components are only a couple of examples of aspects of Oil&Gas business to assure a successful and lasting operation.
Unprocessed crude oil and natural gas possess a variety of impurities, some are to be considered more common than others. These impurities not only affect the product’s overall quality, but also have a considerable impact on the production process, maximization and continuity of production, equipment integrity, ease of transport, and disposal. These will bring additional expenses on oil production companies, therefore, must be treated with an efficient, cost-effective, and safe way.
A complete treatment of crude oil and gas requires correct chemical choice and application. In that regard, oilfield chemical and service companies are a major business partner to production companies. They are constantly called upon to solve many issues encountered during production, and they are tasked with choosing the speciality chemicals to be used and optimizing the chemicals’ use to balance consumption and performance, both requiring expertise, experience, and innovation.
A common yet primary problem faced in oil and gas production is emulsion: A colloidal dispersion form where droplets of one phase is dispersed in a second phase, namely oil and water.
Crude oil is almost always produced as a water-in-oil emulsion. Therefore, it must be passed through a “demulsification” or “dehydration” process, during which the water and dissolved salts in this phase are separated. This is a crucial process to ensure the oil is in acceptable quality for further transportation and treatment in refinery. A common regulation imposed by international trade and most refineries requests the water content to be between 0% and 0,5%, and the salt content to be between 10-25 bbl / 1000 bbl.
Emulsion breaking process is also important for oil reclamation. Emulsion breaking process is equally critical in situations where companies produce crude oil from high water content wells, or target oil reclamation from produced water to maximize crude oil production rate.
NEUCHEMIE’s NEU DM (emulsion breakers) and NEU DO (reverse-emulsion breakers) product lines present speciality demulsifiers and water clarifiers to its customers. Products are formulated depending on customers’ field conditions and requests such as retention times, turbulence levels, water and sediment amounts, and temperature. NEU DM & NEU DO series proposes:
- High levels of water/oil separation,
- Stable and defined interface formation,
- Customizable chemical formulation depending on the oil type and contents,
- Decreased product loss / Increased product reclamation,
- Internationally accepted quality end product,
- Lowered overall costs / Increased profitability.
Foam is a gas dispersion in a continuous liquid phase. It is made up of lamallae stabilized by naturally occuring surfactants like asphaltenes or naphtenic acids, or by added chemicals like some film forming corrosion inhibitors. It is mostly observed in high gas-to-oil ratio formations.
Generally, foaming problems faced in oil & gas sector occur when gas breaks out from crude oil in separators. Foaming problem in 2 or 3 stage separators can result in unregulated level control which can lead to shutdowns, or can cause liquid carryover in gas outlets that can cause flooding in downstream scrubbers. Another cause of foaming which is observed in upstream operations is pressure drops in the presence of foam stabilizing contaminants such as drilling mud, wax, or sand.
NEUCHEMIE’s NEU AF series of products provides antifoams and defoamers to provide total control over these problems. Antifoam chemicals prevents foam formation, while defoamers eliminate already formed foams. NEU AF chemicals will provide:
- Total foam control,
- Elimination of shutdown risks by carryover and flooding,
- Increased separator efficiency,
- Increased pump efficiency and capacity,
- Non-erratic produced fluid flow,
- Controlled and maximized production capacity.
Hydrogen Sulfide, more commonly referred with its chemical nomenclature H2S, is a very toxic and pungent gas that causes numerous problems in both upstream and downstream oil & gas industry. It is a naturally occuring gas that is generated by Sulphate Reducing Bacterias (SRBs) in reservoirs, and it can be found in liquid phase (dissolved in crude oil and produced water), and in gas phase. Aside from its danger to health and environment even in low concentrations; due to its acidic nature, H2S poses a serious threat to field equipment as a primary source of corrosion and Iron Oxide deposition.
NEUCHEMIE’s NEU SCAV series provide H2S Scavengers to remediate these problems by effectively eliminating the H2S gas with a quick and non-reversible reaction. NEU SCAV H2S Scavengers provide:
- Effective H2S scrubbing with rates as low as 2,5 ppm scavenger : 1 ppm H2S,
- Fast reaction times,
- Non-reversible reaction,
- Total solubility in oil and water,
- Elimination of corrosion risk,
- Elimination of Iron Oxide deposition,
- Lower chemical costs,
- Safe to hande and easy to use chemicals.
Microorganisms are an ever-present threat in all phases of oil & gas production. They can be encountered during drilling, production, and refining processes. Hydrogen Sulfide (H2S), microbiologically induced corrosion (MIC) and associated biofouling and biofilms (slime formation, iron oxidation, iron sulfide scaling), steel pitting, cracking, plugging and molding are some of the problems caused by microorganisms.
Some bacteria like the Sulfate-Reducing Bacteria (SRB) are highly resistant to high salinity, high pressures, and high temperatures. Due to their nature, they are colonized in crude oil reservoirs, and are easily carried over throughout the system during production. The bacteria colonizes at a very high rate once it reaches points in the system where the flow rate is low or static.
Eliminating the presence of microorganisms in the reservoir is practically impossible, especially once the colonies are established. Therefore, it is critical to protect the production line and equipment. To ensure that the bacteria carried over with the produced fluids are eliminated and their activity interferred with, “bactericides” or “biocides” are used.
NEUCHEMIE’s NEU CIDE biocide programmes provide total elimination of microorganisms and related problems, offering benefits such as:
- H2S formation control,
- MIC elimination,
- Iron sulphide deposit control,
- Biofilm build-up elimination,
- Plugging control,
- Equipment protection.
Asphaltene is the heaviest component in crude oil, and is a colloidal suspension stabilized by aromatic ring systems. It is generally defined as the fraction of oil that is insoluble in light aliphatic hydrocarbons (pentane, heptane…) but soluble in aromatic solvents like toluene.
It is known to be a major problem in both upstream and downstream operations, blocking reservoir pores in near-well areas; and forming serious deposition in the production tubing, downstream pipeline and facilities, as well as increased stabilization of existing emulsion. Asphaltene becomes observable once the oil stability is disturbed or destabilized by gas breakouts (pressure drop), condensate treatments, gas or gas/liquid injections, acid stimulation, low-pH scale inhibitor squeeze, shear, or crude blending.
Asphaltene is mainly observed in heavy crude oils, and it is a major problem for operations where heavy crude oil production and heavy/light crude blending is undertaken. Detrimental effects of asphaltene is highly costly to production companies, varying from production rate loss to complete renewal of affected equipments and parts.
NEUCHEMIE’s NEU ASGUARD asphaltene dispersants and inhibitors are formulated depending on the structure, molecular weight and mechanism of aggregation of various asphaltenes. The technology offers:
- Increased flow rate by inhibition of asphaltene agglomeration and precipitation,
- Deposit prevention by solubilization of asphaltene colloids,
- Protection of high-risk points in the system like near-well areas and wellheads, tubings and pipelines, and downstream equipments.
Paraffin waxes are solids made up of long-chain compounds that are naturally present in crude oils. As the compound chain gets longer, paraffin wax becomes more observable in forms varying from soft to hard crystalline waxes. In places with high pressure and temperature like the reservoir, any paraffin wax will be solubilized in crude oil. However as the crude oil temperature and pressure drops, wax will begin to precipitate from crude oil, usually in forms of needles or plates. Moreover, for wax formations with longer chains, the melting point is higher, which means the longer the paraffin wax chain is, the more difficult it is to keep the wax from forming deposits.
Paraffin wax deposits are mainly observed in the production line where the pressure and temperature levels are low, and unless treated, will cause plugging and blockages in choke points like manifolds, pumps, and valves; form deposits in pipelines and reduce the flow volume and further increase pressure, causing risk to individual equipment integrity as well as the overall system.
NEUCHEMIE’s NEU PD paraffin wax inhibitors, dispersants, and solvents provide total paraffin wax control by altering its crystalline structure and keeping solidified wax particules in suspension. The wide range of products is formulated in accordance with the specific wax appearance temperature (WAT) or Cloud Point Temperature encountered in an oilfield. NEU PD paraffin wax treaters offer:
- Total prevention of deposit formation,
- Reduced downhole (near well) paraffin deposition,
- Overall equipment protection,
- Improved equipment performace,
- Elimination of paraffin wax related production reduction.
Scale formations are depositions formed by slightly soluble inorganic salts in aqueous solutions. Once a sudden drop in pressure, a change in temperature or pH occurs, ions present in water phase may reach a critical point called super saturation. In this state, the mineral salts become less soluble and begin precipitating. Scale deposits can form on almost any surface, and once a primary layer is formed, it will get continue to get thicker unless treated.
Scaling has various impacts on oil & gas production, varying from pore blockages in near-wellbore region or in the well itself, to narrowing parts of the production conduit’s internal diameter or blocking flow, to even causing detrimental effects in process facility equipments (lowering heat permeability for boilers and heat exchangers, jamming valves, plugging manifolds…). For fields where pH and salt levels, and the type of salt are a high risk factor, scaling can be the single biggest danger to the operation.
The most commonly encountered scaling types in oil industry are calcium carbonate, calcium sulfate, iron/zinc/lead sulfides, and sodium chloride.
NEUCHEMIE’s NEU GUARD scale control agents offer customized solutions that are specifically formulated in accordance with the customers’ type and severity of scale formation, scaling tendency, as well as laboratory and software analyses of the water (ion) and the scale conducted by NEUCHEMIE’s technical experts. Chemical application and survey programs designed for the customer target:

Corrosion is one of the major problems in oil and gas industry. Whether internal or external, corrosion can cause serious equipment damage leading to long shutdown periods, increased repair costs, even environmental impacts due to spills and increased iron carbonate and sulphide depositions.
Corrosion occurs where water and gases like oxygen, hydrogen sulphide, and carbondioxyde are present. The consequences of uncontrolled corrosion can cause embrittlement, pitting and cracking in downhole tubing and equipment, subsea or surface pipelines, pressure vessels, and storage tanks; all leading to deterioration of equipments affected.
NEUCHEMIE’s NEU COR corrosion control compounds are designed to intervene with the existing corrosion occurence, and further protect the system, regardless of type of corrosion and type of application. NEU COR corrosion inhibitors are highly efficient against sweet and sour corrosions, and available to use in downhole, reinjection, production, gas plant, refinery, pipeline applications. NEU COR corrosion inhibitors are formulated in accordance with latest technologies, and are customizable according to customers’ needs.

- Significantly reduced repair costs.
The flow of liquid in a conduit creates friction, leading to pressure drops. Once this pressure drop reaches significant levels, it can create turbulent flow rates and negatively affect the performance of pumps along the line.
NEUCHEMIE’s NEU DR drag reducers provide significant reduction by interacting with the turbulent flow processes, and reduce frictional pressure losses. NEU DR products offer its customers:
- Reduced turbulence and turbulence-related frictional energy losses,
- Increased flow capability in pipelines, hoses, and various other conduits,
- Decreased costs of pumping fluids,
- Decreased pump operating costs,
- Increased pump performance,
- Reduced conduit pressure,
- Decreased transport time.
Pour point defines the lowest temperature at which the crude oil or fuel will pour. Once a temperature lower than this number is reached, lowered flow rates will begin to manifest. In general, pour point is associated with wax content in oil: Higher wax content indicates higher pour point temperature, therefore, lower flow rate. If not treated, this problem will result in agglomerate oil entrapment, flow inhibition, as well as impact on production, transportation and usage.
NEUCHEMIE’s NEU PPD pour point depressants are formulated to prevent wax crystal agglomeration in oils and to provide improved viscosity and ease of flow at lower temperatures. NEU PPD products offer its customers:
- Increased oil flow rates at lower temperatures,
- Increased lubricity and reduced friction for high wax content oil,
- Decreased costs for heating crude oil to improve flow,
Oxygen can be introduced into the system from various sources. Fluids injected during fracturing operations, saltwater disposal wells, formation squeezes, or waterflood operations are the most common sources of oxygen, considering the possibility that they get in contact with open air for a certain amount of time. Due to its acidic nature, dissolved oxygen in water can cause corrosion to equipment. Moreover, the by-products of this type of corrosion can cause formation damage by plugging.
For water injection systems, oxygen is primarily removed either by use of vacuum tower, or a gas-stripping tower. These towers have the capability of reducing oxygen levels from 9 ppm to <50 ppb. However, process protection requires <10 ppb (preferably <5 ppb) oxygen content to avoid serious oxygen corrosion. Oxygen scavengers’ primary role is determined by this requirement.
NEUCHEMIE’s NEU SCAV oxygen scavengers are specifically designed to quickly interact with free oxygen ions present in the medium, and effectively decrease oxygen levels to safe levels. NEU SCAV products offer:
- Effective oxygen scrubbing to safe levels,
- Minimized oxygen-related corrosion,
- Minimized iron oxide deposition and scaling,
- Minimized downtime due to equipment repair,
- Lowered costs of equipment repair and renewal,
- Minimized risk of operational shutdown,
- Minimized use of corrosion inhibitors due to decreased levels of oxygen related corrosion.
