Mathematical modeling of the environmental radioactive pollution during oil and gas wells drilling
(Lviv Politechnic Publishing House, 2017-09-08) Burla, Oksana; Ablieieva, Iryna; Plyatsuk, Leonid; Malovanyy, Myroslav; Sumy State University
The aim of paper was development of an adequate mathematical model for predicting the level of environmental pollution by radionuclides emitted as a result of oil wells drilling. This problem was solved using Gaussian Plume Model which allowed to determine the concentration of radionuclides at a given point in space. Impurity flux density in Bq/(m2 s) was been simulated.
System approach to the assessment of anthropogenic impact on marine ecosystems during oil production activities
(Lviv Politechnic Publishing House, 2018-10-26) Plyatsuk, Leonid; Ablieieva, Iryna; Gabbasova, Sabina; Mamutova, Alua; Sumy State University; Al-Farabi Kazakh National University
The system of quality categories, integrated and single indicators was created for the marine ecosystem under the impact of oil production. On the basis of the integral differential approach, a significant and moderate degree of influence has been substantiated for the stages of drilling the well and extracting oil, as well as an insignificant impact for seismic exploration and decommissioning.
Theoretical substantiation of the petroleum hydrocarbons destruction by specific microflora using anaerobic digestate
(Видавництво Львівської політехніки, 2020-10-10) Ablieieva, Iryna; Sumy State University
Implementation of the proposed approach to bioremediation of oil-contaminated soils provides an intensification of the hydrocarbons degradation process biologically using a digestate as a bio-stimulant, contributes to the production of an ecologically safe substrate, and excludes its toxicity to living organisms due to the degradation of petroleum hydrocarbons.
