EVALUATION OF THE INFLUENCE OF DRILL CUTTINGS COMPOSITION ON HAZARD CLASS FOR THE ENVIRONMENT
Development of oil and gas deposits is associated with the formation of a great number of drill cuttings, that represents drilling waste and a significant negative impact on the environment. Drill cuttings composition which is formed with the allocation of crushed rock from the drilling solution is very heterogeneous and depends on geological conditions, technological process of cleaning of drilling fluid, as well as from the stage of drilling, that corresponds to the waste. The results of studying the influence of chemical composition of solid phase and aqueous extracts of samples of drill cuttings on the class of risk to the environment is shown in this work.
