Biocide

The phenomena of microbiological contamination of the oil and natural gas environment represent a broad issue. The negative effect of microorganisms is primarily associated with the degradation of petroleum hydrocarbons, leading to an increase in oil density, sulfur content and viscosity. These changes cause disruption in oil extraction and processing technology, bringing about significant economic losses. Problems also concern the ways crude oil is stored, products of its processing, drilling fluids, and natural gas. In addition to lowering the content of hydrocarbons in crude oil, adverse activity of micro-organisms causes corrosion of transmission installations (oil and gas pipelines) and the production of undesirable substances (H2S, polymers, organic acids, etc.) that affect the performance of oil and gas. Attempts to eliminate microorganisms involve using chemicals, exhibiting biocidal properties, which besides the physical method is the most popular and most effective technique of eliminating microbiological contamination. Biocide is a chemical substance capable of destroying different forms of living organisms. Some bacteria, like SRB (sulfur reduced bacteria) which forms some algae in crude oil, are harmful for equipments. This will stick on equipment surfaces and reduce performance. Using Biocide helps to get rid of such bacteria and avoid equipment deficiency. The selection of appropriate antibacterial or antifungal agents requires the consideration of factors affecting the efficiency of the process.

Vira Baspar Bartar Co. produces a broad spectrum biocide to prevent of bacteria. We recommend the appropriate biocides for use in oil and gas field application.

H2S Scavenger

The application of sulphide scavengers is a widely adopted practice in production and processing operations in the oil and gas industry. Hydrogen sulfide (H2S) is a very toxic and pungent gas that causes problems in both the upstream and downstream oil and gas industry. The process of removing H2S is known as gas sweetening, by either sponge H2S scrubbers (forming iron sulfide) or chemical scavengers.

We offer hydrogen sulfide scavengers that can be applied via continuous injection or through batch treatments. The benefits of our product include:  Improved safety due to reduced hydrogen sulfide content;

 Removal of H2S gas from process systems, thereby reducing corrosion; and  Maintain asset integrity and reduce the need for replacement equipment.

The features of our offered inhibitors are highly miscible in water, accurate composition, precise pH value, excellent corrosion prevention and biodegradable. The multifunctional chemical for hydrotesting is utilized for preventing pipelines, equipments, valves and various other hydrostatic instruments from corrosion.

Oil /Water Separation Process Chemicals

Oil /water separation by the different gravity of the two phases is a very slow process, but can be accelerated by the assistance of chemicals. The chemicals used are termed demulsifiers, antifoam and water clarifiers /deoilers.

We supply a range of demulsifiers, antifoam and water clarifiers /deoilers that give our customers the confidence that their processes are controlling.

Demulsifier

Emulsion breaking is one of the most complex and situational aspects of oilfield chemistry. Stable emulsions encountered in oil production are normally composed of varying levels of water or brine dispersed in a continuous oil phase. These emulsions are stabilised by compounds occurring naturally in the crude. The severity of the emulsion formed and thus the ease at which it can be broken is dependent on: 1- Physical and chemical properties of the crude oil, 2-Production temperature, 3- Distance between reservoir and topsides, 4- Degree of agitation experienced between reservoir and separator, turbulent flow presence of solids (sand, clay, bacteria, scale, asphaltenes, corrosion product, napthenates) and / or natural surfactants which act to stabilise the emulsion.

Demulsifier or emulsion breakers that separates the water from the "water/crude oil" emulsion. Demulsifier additive chemical breaks the crude oil emulsion into crude oil and water. Demulsifiers are key components of production formulations which enable the quick separation of produced water from oil. Separating crude oil from water can be very time critical due to short residence time.

Vira Baspar Bartar Co. create the new demulsifier formulation for demulsification of crude oil emulsion. Demulsifier selection by us is normally carried out in the field by our highly experienced bottle testing engineers. A wide selection of demulsifier chemistries are screened individually and in the form of blends.

Antifoam

Anti-foaming additive suppresses foam when all types of crude oil tanks are being cleaned. Foaming is a function of crude oil type which either permits small gaseous bubbles to be encased in a thin film of crude oil as the gas comes out of the crude oil solution or permits gaseous bubbles as the viscosity and surface tension of the crude oil changes and mechanically unlocks the gas. Anti-foaming additive avoids operational cost increases due to foam induced crude oil supply disruption. Anti-foaming solutions have employed chemicals, heat, or mechanical processes such as settling, agitation, or centrifugal force. Each process provides solutions, but can also create additional problems necessitating further remediation.

Vira Baspar anti-foaming additive employs new chemistry to solve the foaming challenge without creating additional problems necessitating further remediation.

Silicone-based Vira Baspar defoamers are polymers with silicon backbones. These might be delivered as an oil or a water based emulsion. These are also heavy duty defoamers and are good at both knocking down surface foam and releasing entrained air. Our defoamers are suitable in non-aqueous foaming systems like crude oil and oil refining.

Water clarifiers / Deoilers

Tightening legislation has encouraged many organizations to review their treatment of challenging oil / water mixtures. Depending on the regional requirements, residual oil limits can range from 40 ppm to as low as 10 ppm. For removing residual oil from produced water or separating waste oil and oil sludge, Vira Baspar Bartar Co. offers a broad range of water clarifiers (deoilers), covering different molecular weights, ionicity, and chemistries.

We offer a series of water clarifiers, and chelates designed to work under various production conditions, allowing you to safely and effectively clear your oil and gas production water. The benefits of our products include: 1- improves control of separation vessels; 2- Meets discharge requirements for produced water; 3- Improves injectivity of produced water; 4- Recovers more sellable oil from produced fluids; and 5- Leaves clear water with minimal suspended oil or solids.

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 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 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 sulfate, barium sulfate and strontium sulfate types of scale deposition in oil/gas producing operations and brines.
