The acidizing process requires a range of additives to provide a range of important properties including corrosion inhibition, wetting, rheology control, foaming and deposition control. For additional information please see our products for wellbore cleaners, foaming agent, wetting agents and scale inhibitors.

Asphaltene Control

Asphaltenes are heterocyclic aromatic molecules representing some of the highest molecular weight fractions present in crude oil. Their limited solubility in crude oil can result in deposits forming in the producing well causing production issues.


Emulsifiers are essential components in the formulation of water-miscible metalworking with a broad range of chemistries being employed to provide optimum stability for different oils and water compositions. In addition to emulsification, as a function of their chemical composition they can provide reduced foaming tendency and enhanced lubricity making them useful multifunctional additives. Metalworking fluids applications include soluble oils and semi-synthetic fluids.


Cleaning is an important process in a wide range of oilfield operations, these include rig cleaners, tank cleaners, cutting cleaners and wellbore cleaners. Effective wetting emulsification and penetration of oil-based contaminants such as drilling fluids are essential to facilitate the effective removal, there is a need for additives such as hydrotropes and solvents to ensure optimum formulation stability and performance.

Corrosion Inhibitors

Corrosion is an important issue within the oil and gas industry, with a major implication in terms of cost and safety. Corrosion affects most stages of a well's lifecycle, from drilling to stimulation through to production. Corrosion is complex due to the many diverse variables that can affect its development, requiring a wide range of treatment chemistries to effectively keep it under control to ensure the avoidance of costly downtime and production loss.


Control of foaming can be important in a wide range of oilfield applications. The defoaming products offered by Lankem are based on ethylene oxide-propylene, oxide-copolymers that can be effective for a range of aqueous systems.

Demulsifier Components

Demulsifying is a complex application within the oilfield chemical industry, facilitating the economical removal of water from crude oil and the clarification of produced water before discharge. Demulsifier system components are based on a wide range of chemistries, including polyols, sulfonates and specially designed molecules.


Dispersing is important in a wide range of oilfield applications. The dispersants offered by Lankem can effectively suspend organic and inorganic materials into aqueous and oil-based systems such as drilling fluids. These materials are based on ethylene oxide-propylene, oxide copolymers, alkylbenzene sulfonates, castor oil ethoxylates and amine ethoxylates.

Drilling fluids

Drilling fluids must effectively provide several characteristics that are essential for a successful drilling operation including, carrying cuttings to the surface, preventing drill-bit clogging, providing lubrication, inhibiting formation damage and optimum fluid weighting. Providing these key characteristics across the range of oil and water-based drilling fluids requires a broad range of properties including, emulsification, foaming, defoaming, wetting, dispersion and lubrication.


Emulsification is an important function during the production of many oilfield products. Whether it's drilling fluids or enabling the dispersion of water-insoluble materials into aqueous systems.

Foaming Agent Boosters

Foaming is an important characteristic for a range of oilfield processes, with the need for effective foam stability over a wide range of temperatures and water compositions. Foaming agent selection is critical to ensure stable foam formation in solutions containing a high level of electrolyte including divalent metals, acid and basic solutions and over a broad range of temperatures.


Lubrication is important in oilfield operations including applications such as drilling fluids and hydraulic fluids.

Paraffin Control

Crude oils can contain naturally occurring long chains of n-paraffin’s that can give issues with precipitation of wax crystals at a lower temperature or if lower molecular weight components are lost during production. Paraffin formation can be minimised by the use of surfactant based dispersants, these can also give beneficial properties in the removal of any paraffin deposits that have formed during production.

Scale Control

Scale inhibitors are vital for ensuring the performance of oilfield operations to prevent the precipitation of inorganic solids from supersaturated water which is co-produced with most hydrocarbons. Scale inhibitors assist with oil and gas production maintaining asset integrity, prolonging the life of wells and reducing downtime from the need for mechanical, acid, chemical cleanout.

Hydrotropes and Solvents

Hydrotropes and solvents can be useful additives in a range of oilfield applications. They can improve the stability and physical characteristics of formulations, increase the solubility of components and boost the overall performance of the formulation.

Wetting Agents


Wetting is an essential criterion in a broad range of applications, the optimum wetting agent is dictated by several parameters, including temperature, pH electrolyte concentration/composition and substrate.
