The drilling of any oil and gas well is accompanied by the use of drilling fluids consisting of chemical reagents and materials of varying degrees of environmental hazard. Existing drilling waste disposal technologies are expensive, energy- and labor-intensive, and do not always contribute to the formation of environmentally friendly compounds. ). In this regard, the possibility of using destructor microorganisms capable of growing and exhibiting active biochemical activity under conditions of complex pollution, in an environment with a high content of hydrocarbons, surfactants and polymer additives capable of biodegrading these substances, is relevant. In connection with the foregoing, the search for new strains of bacteria for the disposal of drilling waste, which are resistant to the conditions of complex toxic effects of drilling cuttings components and, at the same time, capable of providing a significant degree of detoxification of reagents that are part of hydrocarbon-based solutions, is relevant.
