Pukish A. The Enhancement of Environmental Safety of Oil and Gas Drilling Sites Construction

Object of investigation – environmental impacts of oil wells construction; purpose of investigation – development and implementation of methods and instruments for the reduction of environmental impacts of wastes produced in the process of oil wells construction; methods of investigation – analytical generalization of known scientific and technical results, system analysis, experimental investigations of technological processes. Calculations were conducted using standard techniques. Novelty: for the first time regularity of drilling wastewaters treatment efficiency enhancement was established using aluminum hydrochloridesulphate; for the first time limits of reagent coagulation method application to the treatment of drilling wastewaters were defined depending on the concentration of suspended particles and organic admixtures; thermodynamic principles of nonequilibrium coagulation processes were further developed; system of groundwater quality monitoring in the process of oil and gas well construction was improved; method of drilling wastewaters toxicity assessment was further developed.
