Biocides are a diverse group of substances, including preservatives, insecticides, disinfectants, and pesticides used to control organisms that are harmful to human or animal health or that cause damage to natural or manufactured products and other assets.

A biocide is a chemical substance or microorganism intended to destroy, deter, render harmless, or exert a controlling effect on any harmful organism. Biocidal products protect people and animals, preserve goods, stop pests like insects or rodents, and control viruses, bacteria, and fungi through a chemical or biological action. Typical examples of biocides are disinfectants, wood preservatives, and insect repellents. Generally, a biocidal product will be a mixture of chemicals and will include the 'active substance.' The active substance has the controlling effect on the harmful organism. In oilfield operations, biocides effectively treat bacterial metabolisms, such as acids, scales, slime, and poisonous gases.

Biocides are also used to protect metallic and polymeric structures from rusting, and eroding, and pipelines and reservoir tanks from bacterial growth. Many bacteria and microbes are found in oil and gas production wells and equipment. Microbiological contamination of the oil and natural gas environment represents a broad issue. The negative effect of microorganisms is primarily associated with the degradation of petroleum hydrocarbons, leading to an increase in oil density, sulfur content, and viscosity. These changes disrupt oil extraction and processing technology, bringing about significant economic losses. The issue also concerns how crude oil is stored, products of its processing, drilling fluids, and natural gas. In addition to lowering the content of hydrocarbons in crude oil, adverse activity of microorganisms causes corrosion of transmission installations of oil and gas pipelines and the production of undesirable substances (H2S, polymers, organic acids, etc.) that affect the performance of oil and gas.

Biocides used in the petroleum and gas mining industry should meet the basic requirements- they should have high biocidal capabilities in a broad spectrum of activity, long duration of action, good solubility in water and hydrocarbons, and chemical and thermal stability. Biocides also should be environmentally friendly, effective at low concentrations, not cause chemical contamination, and made from cheap and commonly accessible materials. The lack of side effects, such as destroying the catalysts used in oil processing, is significant. Interaction with the solution's components pumped into the hole must not cause any changes to its chemical and physical properties. At Centum, our scientists and engineers have addressed the above issues via research, development, and testing. We have been testing the effectiveness of the biocide chemicals in the marketplace. Upon successful testing and trials, we have developed BioShield.

BioShield

Centum’s new-generation biocide control additive, BioShield, is the most effective additive for various oilfield operations. Our biocide blend is all-in-one and ready for onshore and offshore oilfield operations. It is a sustainable formula designed to meet ESG targets without compromising performance. All the ingredients in our biocide chemical are locally sourced and readily and ultimately biodegradable. Centum's BioShield is the ultimate choice for protecting your oilfield operation from biocides. At Centum, we carefully engineer BioShield to meet your specific application needs, and it is most effective in all geological conditions. Our biocide is non-toxic to fish, animals, and human health; BioShield is selectively designed to kill harmful and unwanted bacteria, viruses, and microbes. It provides maximum worker and workplace safety and helps to cut oilfield operational costs significantly.
