OIL & GAS

The oil & gas industry is constantly seeking innovative solutions to improve efficiency and maximize recoverable resources. Enter nanobubble technology in oil and gas industry, a revolutionary approach that harnesses the power of nanoscopic gas bubbles to unlock trapped oil reserves while minimizing environmental impact.

These NICO Nanobubbles possess unique properties that hold immense potential for enhanced oil recovery (EOR). Unlike traditional methods that rely on harsh chemicals, nanobubble solutions for oil recovery and gas production offer a cleaner and more efficient approach.

NICO DRONA: Nanobubble Technology for Oil & Gas Water Treatment

NICO DRONA is an advanced nanobubble generator system designed to enhance gas–liquid interaction and improve water-treatment performance across oil and gas operations. By generating nanobubbles typically measuring <200 nm, with gas transfer efficiency exceeding 85% under specified operating conditions, NICO DRONA supports improved oxygen transfer, oxidation, hydrocarbon separation, and biological treatment processes. The system can be integrated into suitable produced-water treatment systems, refinery wastewater plants, offshore platforms, and industrial process-water loops. Depending on the application, NICO DRONA can support water-quality improvement, contaminant removal, odour management, and process optimization, helping operators evaluate opportunities for water reuse and more efficient treatment operations.

Key Applications in Oil & Gas Industry

• Enhanced Oil Recovery (EOR): Nanobubble technology in oil and gas industry can be used in water flooding and gas injection methods to increase oil extraction efficiency. Their small size allows them to penetrate deeper into reservoirs, reducing surface tension and improving the displacement of trapped oil.
• Wastewater Treatment: In the oil and gas industry, wastewater often contains hydrocarbons and other pollutants. Nanobubbles for Oil and Gas can improve wastewater treatment efficiency by enhancing contaminant breakdown, reducing chemical usage, and increasing dissolved oxygen levels to support biodegradation.
• Pipeline Cleaning: Nanobubble applications in oil and gas industry can be employed to clean and maintain pipelines, removing scale, biofilm, and other deposits. Their ability to deliver active agents efficiently ensures thorough cleaning without the need for harsh chemicals or mechanical methods.
• Corrosion Control: By improving the distribution of corrosion inhibitors through the water phase, nanobubble technology in oil and gas industry helps better protect equipment and pipelines from corrosion, thus extending their operational life and reducing maintenance costs.
• Gas Separation & Recovery: Nanobubble technology in oil and gas enhances the efficiency of gas separation processes, such as hydrogen sulphide removal or carbon dioxide capture, which are crucial in refining and processing operations.

Produced Water Treatment and Reuse

Produced water is generated during oil and gas extraction and may contain dispersed hydrocarbons, suspended solids, dissolved compounds, and other contaminants. NICO DRONA supports produced-water treatment by enhancing gas–liquid interaction and supporting oxidation, hydrocarbon separation, and flotation processes. Under suitable operating conditions, these processes can target 15–30% reductions in oil content and COD, improving the potential for downstream treatment and water reuse. For dissolved air flotation (DAF) and induced gas flotation (IGF) systems, nanobubble integration can be evaluated to improve oil droplet separation and flotation performance, with potential improvements of 15–25% in oil flotation efficiency. Actual performance depends on influent characteristics, existing separation technology, gas selection, and operating conditions. Integrating nanobubble technology into suitable produced-water treatment systems can help operators optimize existing processes and assess opportunities to improve treatment efficiency. The required configuration depends on the composition of the produced water, flow rate, oil content, treatment objectives, and applicable discharge or reuse standards.

Refinery Wastewater, Sludge and Drilling Mud Treatment

Refinery wastewater can contain hydrocarbons, organic pollutants, suspended matter, and other process-related contaminants. NICO DRONA can support refinery wastewater treatment by improving gas transfer and oxidation, as well as supporting contaminant separation and biological treatment where applicable. In suitable applications, improved treatment performance may contribute to 15–35% improvements in BOD/COD removal through biological treatment processes. For sludge, tank-bottom water, and drilling mud treatment, nanobubble technology can be evaluated to support treatment performance and process stability. The selection of gas, system configuration, and treatment approach depends on the waste stream and the intended outcome. Site-specific testing helps establish the suitability of the technology for each application.

Hydrogen Sulphide and Odour Control

Hydrogen sulphide (H₂S) can create odour, corrosion, and operational challenges in oil and gas water systems. NICO DRONA supports water-treatment processes that can help address sulphide-related contamination and associated odours, depending on the water chemistry and treatment configuration. For suitable lagoon remediation applications, treatment programmes may target 50–80% reductions in H₂S and odour levels. Appropriate gas selection, dosing, and process control are essential to achieving the desired treatment outcome.

Pipeline Biofilm and Process-Water Management

Biofilm accumulation and biological growth can affect pipeline performance, water quality, and maintenance requirements. NICO DRONA can be evaluated in suitable process-water systems to support biofilm management and improve water-treatment performance. Its integration into existing process loops allows operators to assess the technology alongside their current cleaning, filtration, and water-management practices.

Aeration Energy Optimization and Chemical Reduction

Aeration can account for a substantial share of energy consumption in biological wastewater treatment. By enhancing gas transfer and dissolved oxygen management, NICO DRONA can help optimize aeration performance. Under suitable operating conditions, nanobubble integration may target 15–40% savings in aeration energy consumption by reducing the energy required to meet oxygen-transfer demands. Nanobubble-assisted treatment may also help optimize chemical use in suitable separation and treatment processes. Depending on the influent characteristics and existing chemical-treatment programme, coagulant and polymer consumption may be reduced by 15–30%. Actual savings depend on baseline chemical dosage, treatment objectives, water chemistry, and process configuration.

Membrane Pretreatment and Fouling Management

For oil and gas facilities using membrane-based water treatment or reuse systems, appropriate pretreatment is important for controlling suspended matter, residual oil, and fouling. NICO DRONA nanobubble systems can be evaluated as part of an integrated pretreatment strategy, with potential targets of 15–35% reduction in membrane fouling indicators under suitable conditions. Performance depends on membrane type, feed-water quality, pretreatment design, and operating parameters.

Enhanced Oil Recovery and Injection Water

Nanobubble technology can also be evaluated in enhanced oil recovery (EOR) and injection-water applications. Depending on the reservoir characteristics, injected gas, fluid properties, and recovery strategy, nanobubble-assisted approaches may target incremental oil recovery improvements of 5–20%. These outcomes require reservoir-specific evaluation and field validation before they can be treated as project performance estimates.
