  • What are the applications of biocides in the oilfield?
  • The other major application for biocides in the oilfield is in biofouling control. This can be defined as the use of a biocide to kill microorganisms that are present in the water that is either injected into an oilfield, or the water that is produced from the oilfield.
  • Why are biocides important in oil & gas production?
  • They play an important role in the life of an oilfield and are a valuable tool in ensuring that oil and gas are produced safely and reliably. This chapter will describe various aspects of the use of biocides in the production of oil and gas.
  • Does water contain biocides?
  • Aerobic and anaerobic bacteria can be present in all water-containing fluids. Studies have reported varied resistance levels to biocides commonly used in oil and gas, referring to consortia enriched from produced water samples, indicating a specific response to each biocide.
  • How are injection water biocides added?
  • Most injection water biocides are added via slug doses as opposed to addition on a continuous basis. The advantage of slug dosing of biocide is that high concentrations are added for shorter periods of time. This method of treatment is usually more efficacious than treating with lower doses for longer periods of time ( Grobe et al, 2002 ).
