Biocide PT Bio-7

The biocide PT Bio-7 is applied for growth inhibit of the sulfate-reducing bacteria causing microbiological corrosion of the oilfield equipment.

Biocide loadings depend on bacteria concentration and bacteria type:
— 10–100 g/tn for sulfate-reducing bacteria
— 100–500 g/tn for adhesive cells


– Prevent hydrogen saturation of steel
– Prevent colmatation by bacteria activity products
– Reduce the rate of H₂S and Carbon Dioxide corrosion
– Has non-emulsifying properties– Creates a protective film that prevents the paraffin adhesion
