Oil Field Chemicals

Flow Assurance Chemicals

Moving produced oil and gas from the reservoir to the point of sale or final disposition involves effectively mitigating potentially problematic challenges, including gas hydrates, asphaltene, wax, scale, emulsions, corrosion and naphthenates. The financial loss incurred from unscheduled production interruption or asset damage due to a flow assurance event can be significant. Improperly applied chemicals can lead to precipitation of insoluble mineral scale deposits while producing and transporting hydrocarbon and produced water. This may cause formation damage or solid deposits in flow lines, which can lead to reduced production and potentially catastrophic blockages in the pipelines. We offer a full solution flow assurance service to ensure the successful and cost- effective flow of hydrocarbon streams from the reservoir to the point of sale. Vira Baspar’s best-in-class chemistries are formulated as multifunctional for the mitigation of a variety of oil production issues including wax, asphaltene, gas hydrate and scale.

Wax Inhibitor

Many crudes contain dissolved waxes that can precipitate and deposit under the appropriate environmental conditions during production, transportation, or storage. These can build up in production equipment and pipelines, potentially restricting flow (reducing volume produced) and creating other problems. Important factors influencing paraffin wax precipitation are: temperature, climatic conditions, cooling rates of storage tanks and pipelines, and rheological parameters in the pipelines. Vira Baspar’s wax inhibitor comprises a range of specialty products taken from different chemical classes. It helps prevent wax-induced plugging of pipelines and improves the rheological properties of highly viscous, paraffinic crudes. Our products help to make your pipeline operations more effective, through avoiding pumping interruptions and reducing total costs.

Asphaltene Inhibitor

Asphaltene molecules are present in most liquid oil and gas streams, and can easily be destabilized by a variety of inherent production scenarios. Once destabilized, they may precipitate and partition to the oil/water interface, or adhere to the surfaces of piping and equipment. These reactions can cause production losses with blocked pipelines, reduced production flow, difficulty in vessel level control, and reduced system efficiency. Asphaltene inhibitors prevent the aggregation of asphaltene molecules so the chemical treatment could be as an injection into the wellbore. Asphaltene inhibitors also commonly work as asphaltene dispersants (ADs), thereby dispersing ready-formed asphaltene agglomerates. Therefore, the treatment products will also perform when injected into pipelines and will improve crude oil transportation. Asphaltene inhibitor (AI) refers to chemical additives that help prevent asphaltene deposition when dosed at very low concentrations into the oil (up to a few hundred parts per million by volume), unlike asphaltene solvents that typically require much higher concentrations to work (percent level). Vira Baspar has a wide selection of asphaltene inhibitors, dispersants and specialty chemical solutions to treat asphaltene stability related issues. These solutions provide a customized chemical application process that will help mitigate the risks related to the production of unstable asphaltenic crude. The benefits are 1- Reduce the precipitation of asphaltenes from crude oil; 2- Maximize production potential by preventing deposition/restriction in flowlines and tubulars; 3- Preserve asset integrity and reliability of subsea wells and flowlines; and 4- Optimize performance of surface treating operations, maintaining throughput and minimizing down time.

Drag reducing agent

Drag Reducing Agents reduce the frictional pressure within the flow of a pipeline or
conduit. Acting as buffers along the pipe wall, drag reducing agents are long-chain
hydrocarbon polymers that decrease the amount of energy lost in turbulent formation.
Using drag reducing agents enables operators to increase pipeline flow using the same
amount of energy, or decrease the pressure drop for the same fluid flow rate.
Vira Baspar drag reducing agents form part of our extensive oilfield chemicals range.
Easy to handle with an extensive operating temperature range from -50°C to 40°C our
products are suited to both crude and refined oil applications.

Vira Baspar drag reducing agents engineered to:

Increase pipeline flow capacity and optimize efficiency by reducing line pressure

Eliminate additional costs by eliminating intermediate pump stations from system designs

De-bottleneck pipeline systems without expensive equipment upgrades

Reduce energy consumption by minimizing drag within the pipeline

Lower operating pressure without sacrificing pipeline capacity

Gas hydrate inhibitor

The formation of gas hydrates is a major nuisance to the oil and gas industry, causing pipelines to plug, gas flow disruptions and safety issues. The gas hydrate formation in oil and gas pipelines is an undesirable situation, undermining the flow assurance programs in addition to posing threat to the personnel and equipment. Clathrate hydrates are non-stoichiometric mixtures of water and natural gas in which the gas molecules are trapped in polygonal crystalline structure made of water molecules. The water molecules arrange themselves in an orderly fashion around the gas molecules, thus entrapping them. These gas hydrates have the appearance of ice but can form well above the freezing point of water at high pressures. Vira Baspar has a highly effective and evolving suite of chemicals, equipment, and services that are at the forefront of industry efforts regarding low-dosage hydrate inhibitors (LDHIs). These inhibitors form part of the PREVENT suite of trusted products and services to preempt and mitigate production issues. The LDHI portfolio is environmentally acceptable and provides capex-efficient alternatives to commonly used thermodynamic inhibitors such as methanol and glycol. Vira Baspar LDHIs maintain flow either by interfering with the mechanism of hydrate formation or by preventing small gas-hydrate particles from agglomerating, thereby helping to ensure that production is maximized and equipment unaffected.

Scale inhibitor

Oilfield scale inhibition is the process of preventing the formation of scale from blocking or hindering fluid flow through pipelines, valves, and pumps used in oil production and processing. Scale inhibitors are a class of specialty chemicals that are used to slow or prevent scaling in water systems. Oilfield scaling is the precipitation and accumulation of insoluble crystals (salts) from a mixture of incompatible aqueous phases in oil processing systems. Scale is a common term in the oil industry used to describe solid deposits that grow over time, blocking and hindering fluid flow through pipelines, valves, pumps etc. with significant reduction in production rates and equipment damages. Scaling represents a major challenge for flow assurance in the oil and gas industry. Examples of oilfield scales are calcium carbonate (limescale), iron sulfides, barium sulfate and strontium sulfate. Scale inhibition encompasses the processes or techniques employed to treat scaling problems. Inorganic scales refer to mineral deposits that occur when the formation water mixes with different brines such as injection water. The mixing changes causes reaction between incompatible ions and changes the thermodynamic and equilibrium state of the reservoir fluids. Supersaturation and subsequent deposition of the inorganic salts occur. The most common types of inorganic scales known to the oil/gas industry are carbonates and sulfates; sulfides and chlorites are often encountered. Our specially formulated scale inhibitors can give excellent protection from calcium carbonate, calcium sulfate, barium sulfate and strontium sulfate types of scale deposition in oil/gas producing operations and brines.
