Abstract

Drilling wells is an ecologically dangerous type of work accompanied by contamination of soil, subsurface and surface waters, pollution of open air with drilling and technological wastes. Throughout the drilling process, drilling waste is generated, such as drilling muds, return drilling muds, drilling waste water. The resulting waste is usually disposed of at landfills, which ensure minimal environmental impact. The use of drilling muds in other spheres is hindered by the complex composition of oily waste. Samples of liquids and solids in drilling wastes, picked at three locations, were subjects for analysis. The waste sample was analyzed for moisture content, organic substances, oil products, silicon, iron and other substances. Based on the studies performed, the authors propose additional introduction of substances possessing high sorption capacity into drilling mud to improve its properties. The most effective way should be using a sorbent capable of retaining organic and heavy metals. The resultant homogeneous soil-like mixture possesses the necessary and sufficient properties to be used as a mineral base for remediation after performing construction work in urban areas.

Highlights

Despite the high environmental threats associated with drilling operation, the negative impact of the generated drilling wastes, as well as the minimum amount of the waste treatment, we observe the widespread expansion of the territories where drilling is performed
A lot of scientists are engaged in research on waste treatment, various methods for the recovery of drilling wastes are being developed [1,2,3,4,5]
To determine the physical and chemical composition properties, we considered the samples of liquids and solids of drilling wastes picked from 3 locations: 1. Vibrating screen

Summary

Introduction

Despite the high environmental threats associated with drilling operation, the negative impact of the generated drilling wastes, as well as the minimum amount of the waste treatment, we observe the widespread expansion of the territories where drilling is performed. A lot of scientists are engaged in research on waste treatment, various methods for the recovery of drilling wastes are being developed [1,2,3,4,5]. Large oil companies store drilling muds at cluster pads [10,11], research various additives and reagents allowing the drilling muds to be converted into fuel, fertilizers or construction soil. The utilization of such material is possible provided it is not contaminated [12]
