Produced water is chemically aggressive: high salinity, scaling ions, dissolved sulphide and trace metals all threaten equipment and discharge compliance. Inorganic control is as important as deoiling.
Deoiling, softening and polishing of produced water for discharge, reuse or reinjection.
Flotation for removal of dispersed oil and fine solids from oilfield water.
Primary gravity and plate separation of free oil and solids ahead of polishing.
Carbonate and sulphate scales precipitate as pressure and temperature change, fouling vessels and injection wells.
Sulphate-reducing bacteria generate hydrogen sulphide, raising toxicity, corrosion and iron-sulphide solids.
Trace heavy metals and naturally occurring radioactive material partition to solids and scale, requiring controlled handling.
Scale-inhibitor dosing and selective softening manage carbonate and sulphate scaling risk.
Aeration or chemical oxidation converts dissolved sulphide to manageable forms and controls souring.
pH-controlled precipitation and filtration remove metals and oxidised solids.
Oily and inorganic solids are dewatered for compliant disposal.
Where present, NORM-bearing solids are managed under the applicable radiological controls.
Material selection and chemical control protect the plant from aggressive chemistry.
Reynolds & Bauhm delivers this scope as part of an integrated, single-point engagement matched to your project, programme and regulatory regime.
Produced water carries a difficult chemistry that must be managed to protect equipment and meet discharge or reinjection limits. Dissolved ions form mineral scale that blocks lines and fouls equipment; sulphate-reducing bacteria can sour the system and generate corrosive, toxic hydrogen sulphide; and dissolved heavy metals must be brought within tight limits. We address each with the right combination of scale inhibition or softening, biocide and souring control, and metals precipitation or polishing — designed around an analysis of the actual produced water and its variability. The aim is a treatment scheme that keeps the system clean, safe and compliant across the changing chemistry a producing field delivers over its life.
