Ecological and Radiation Assessment of the State of Drilling Waste and their Disposal Products on the Example of the Khanty-Mansiysk Autonomous Okrug - Yugra

Abstract

The development of the infrastructure of the oil and gas complex is one of the most significant factors of negative impact on the environment. The most efficient way to drill wells is cluster drilling, which currently accounts for 95% of all operations carried out in fields. In the process of oil and oil products production, toxic drilling waste is generated at the well pad, which is then placed in sludge pits (sludge storage). The aim of the study was to select the methods for drilling waste utilization based on the results of environmental radiation analysis. Within the framework of the study, the following tasks were solved: radiation monitoring of drilling waste was carried out at the “Progress-2000” spectrometric complex; analyzed the physical and chemical composition of drill cuttings; a comparative analysis of the samples under study was carried out in accordance with the normative indicators; methods of utilization of drilling waste are proposed.
