Water Treatment Chemicals
- Biocides: Control microbial growth in water systems, preventing the formation of biofilms and corrosion.
- Flocculants: Facilitate the separation of suspended solids in water, improving effluent quality.
- Dehydrating agents: They remove water from sludge, facilitating its disposal.
- Clarifiers: They accelerate the sedimentation of suspended solids in water.
Well Completion Chemicals
- Completion fluids: Water-based and oil-based surfactants. Used to facilitate the placement of pipe and equipment in the well.
- Lubricants: Reduce friction and torque during drilling, improving penetration rate.
- Gels and rubbers: Used to control fluid loss and improve wellbore stability.
Drilling Mud Additives
- Emulsifiers: Primary and secondary. Used to stabilise water-in-oil or oil-in-water emulsions, improving lubrication and solids suspension.
- Filtration controllers: PAC, EDTA, bentonite. They regulate fluid loss from the mud to the formation, maintaining wellbore stability.
- Dispersants: Improve the geological properties of slurries, facilitating drilling.
- Viscosifiers: Increase the viscosity of muds, improving their ability to transport cuttings.
- Bentonite improvers: Increase the viscosity and solids suspension capacity of bentonite, improving mud performance.
- Clay inhibitors: Prevent the swelling of clays, improving wellbore stability and reducing friction.
- Defoamers: Reduce foaming in muds, improving drilling efficiency.
- Surfactants: Improve the wetting, dispersing and emulsifying properties of muds.
Well Stimulation Chemicals
- Corrosion inhibitors: Protect pipelines and equipment from corrosion during acidising processes.
- Setting accelerators and retarders: Control the setting time of cement, optimising completion operations.
Other Chemicals
- Crude oil recovery chemicals: Surfactants, polymers and other chemicals used to enhance oil recovery from formations.
- Materials chemicals: Some products, such as aluminium silicates and benzoic acid, can be used in the manufacture of other materials.
