Oil and Gas Industry
Anolyte and Catholyte solutions have been used for stimulation and enhancement of oil and gas production and to improve performance of drilling fluids. Anolyte is a highly effective alternative to bactericides that are non-biodegradable or bio-accumulative. As a bactericide, Anolyte is selective, targeting bacteria responsible for microbial induced corrosion and slime while being safe to humans. Catholyte has been used to replace diesel oil as a cleaning solution for drill bits and tools on site.
Envirolyte solutions can be used to enhance production from wells which have been impacted by down-hole growth of bacteria, and other micro-organisms, by killing the bacteria and removing the restrictive biomass. Water used for the fracturing of oil and gas wells can be treated to manage bacteria, protecting fracturing fluids and gels, and ensuring polymer and improved performance. Anolyte solutions remove scale and slime build-up from pipes, and cooling water systems can be kept free of biomass, improving heat exchange values and eliminating corrosion caused microbial induced corrosion (MIC). Produced water may be treated before being revised in stimulation fluids or water floods. Recent data collected from field operations where frac water was treated with anolyte, shows that the bacteria levels in the frac water were reduced below the threshold level that would adversely impact stimulation fluids and gels.
Catholyte has been shown to substantially reduce the surface tension of water and can be used to condition water used to stimulate well production. Anolyte has some catholyte properties as well and, being a biocide, is a surfactants itself to some extent. Use of anolyte along with catholyte at the oil rigs results in recovering more oil using low cost and environmentally friendly ingredients. In addition, Anolyte prevents microbial contamination of down hole injection of water during recovery and reduces the need for traditional disinfection chemicals, which can be expensive, highly toxic and potentially hazardous for to transport and store.
