How Oxiteno works

Drilling fluids are critical in oil and gas exploration, as they maintain a well's stability, cool and lubricate the drill bit, and help to remove grit. Oxiteno  optimizes drilling productivity with a wide range of additives for drilling fluids and well-cleaning agents.

Its entire line of humectants, lubricants (ULTRAFLUID®), continuous phase (ULTROIL® OE), helps guarantee the high performance and stability required by the challenges faced in drilling activities.

For the challenges in this stage, different types of drilling fluids are used and usually rated according to their main base (continuous phase). Oxiteno provides solutions adapted to each type of fluid and technology, such as ULTROIL® OE 040, made of base oils with low aromatic content for oil-based drilling fluids (OBM).

Lubricants are important additives used in drilling fluids to guarantee the integrity of the drill string and reduce friction to achieve higher penetration speeds during drilling. The ULTRAFLUID® line, which includes natural and  synthetic-based lubricants, features high biodegradability and low toxicity,  assuring the efficiency of this step. The cleaning agent, ULTROIL® WM 1001,  completes this line. Its proprietary combination of ingredients is excellent for  dissolving and dispersing oil or synthetic-based fluid residues, leaving the well,  tubing, and metal surfaces free of oil deposits, even at low application rates and  under high salinity conditions.

Applications:

• Lubricants
• Casing Cleaners
• Additives
• Humectants
• Continuous phase

Oxiteno serves the well stimulation stage with a complete line of emulsion preventers, surfactants for stimulation and hydraulic fracturing, and specific solvents. Its solutions act in the stimulation of wells providing better performance in  well intervention and hydrocarbon recovery operations.

The emulsion preventers in the ULTRAWET® line prevent the oil from mixing with the injected fluids, enhancing the efficiency of stimulation operations with the use of acid solutions where the formation of these emulsions is common. This low toxicity product line delivers high performance even in different types of oil and fluids, ensuring the integrity of these fluids in a wide range of applications.

Oxiteno also has a research pipeline for the development of green solvents and surfactants to remove different types of paraffin and asphaltenes.

Applications:

• Emulsion preventers
• Surfactants
• Flowback Solutions
• Specific solvents

The separation phase is one of the most critical stages in oil production. In this step, the efficiency of the process to separate the resulting fluids directly impacts operational cost. Therefore, the stage of breaking the emulsion and dehydrating the oil is extremely important and ensures productivity and competitiveness
for service companies.

ULTROIL® EB is a streamlined line of intermediates for demulsifying formulations that help to destabilize the oil emulsion, ensuring the quality of the different phases (oil and water) and increasing productivity in oil recovery.

The components of a demulsifying formulation are rated according to their different functions and the features they deliver during the oil emulsion treatment. Oxiteno's portfolio includes the demulsifying bases in the ULTROIL® EB line, and several additives that have different actions in breaking down emulsions, and can also act as a hybrid - that is, with more than one function depending on the type of emulsion:

Droppers: Improve the coalescence process of water droplets, boosting speed in the fluid separation process, as well as the excellent quality of the separated phases.

Dryers / Treaters: Agents that increase the efficiency of oil emulsion treatment, inducing the flocculation and coalescence of the dispersed phase, and delivering excellent oil dehydration results.

Wetting Agents: Interact with solids that may be present in the emulsion, changing their wettability features and destabilizing the emulsion.

The observed results of water separation for some of the products and their simple combination are illustrated in the graph and the image below. For more information about the products and recommendations for use, contact our Technical Assistance team.

Applications:

• Demulsifiers
• Foamers

The products of this technological platform are intended to guarantee the useful life of the equipment used in the exploration and production of oil and gas.

The ULTROIL® CI intermediates line creates a protective film to prevent corrosion, which poses a serious threat to the assets of the oil and gas industry at all stages, from exploration to production and refining.

Used in formulations of corrosion inhibitors, the ULTROIL® CI line provides anti-corrosion protection on internal surfaces, maintaining the integrity of metallic materials used in the transport and storage of hydrocarbons and reducing the formation of sediments and the wear of the metallic material.

On this platform, we also have the H₂S sequestrant, ULTROIL® SV 70, which removes H₂S from oil, reducing health and environmental hazards and ensuring the safety of the operation.

Applications:

• Corrosion inhibitors
• H₂S sequestrant
