Microbial control in the Oil & Gas industry is a part of a larger corrosion control and chemical treatment program. The use of the correct biocide helps to maintain asset integrity by preventing corrosion, improving overall production efficiency, and preventing environmental damage by mitigating sources of corrosion failure.
Biocides are used to kill microorganisms which include sulfate reducing bacteria, slime forming bacteria, and algae. These microorganisms attack polymeric drilling muds, completion and workover fluids, slick waters, fracturing fluids, etc., and can cause deterioration of the fluid system and reduced effectiveness of the well treatments.
Drilling
Water-based drilling fluids, commonly referred to as drilling muds, are highly susceptible to microbial contamination. LANXESS preservatives are able to help maintain the integrity of drilling muds by offering fast-acting biocides that are effective long-term.
Completion & Workover Fluids
Completion and workover fluids play a major role in the commercialization of a producing formation. LANXESS helps to minimize the possibility of microbial contamination in the reservoir with highly effective and salt tolerant biocides.
Packer Fluids
Packer fluid is liquid used in a well when a packer is between the tubing and the casing. Microbial degradation of the fluid can be prevented with long term biocides offered by LANXESS Material Protection Products.
Well Stimulation
LANXESS biocides help to optimize your gas well production by controlling the introduction of microorganisms associated with MIC (Microbially Influenced Corrosion) and enabling the reuse of water by preserving the fluid quality (e.g. minimizing H2S generation) with an easy to handle long-term biocide.
Storage
Microbial contamination of storage tanks, pipelines, and transmission facilities is unavoidable. Negative effects include the silting of reservoir rocks, clogging of pipelines, and accumulation of sediments at the bottom of fuel tanks. Microbial degradation of the liquid can be minimized using biocides offered by LANXESS.
