Utilization of drilling waste when drilling wells in the fields of the western oil and gas region of Ukraine

Abstract

Abstract The article analyzes known technological solutions for storage and processing of well drilling waste. The advantage of the solution is the presence of a soil-cement coating. The authors propose to fill the waste repository with alternating layers of drilling mud and fly ash of the Darnytsia Thermal Power Plant. The authors advise to use sorbents for neutralization of petroleum products as needed. It is suggested to introduce the sorbent periodically into the mud storage barn. The thickness of the layers for disposal with the addition of ash was chosen in order to obtain optimal humidity. It is proposed to add ash removed from the Darnytsia Thermal Power Plant when arranging the walls and coating of the mud storage tank from soil cement. When adding 10% of ash by weight of cement, the compressive strength increases by 8.01% on average, and when adding 20% - by 12.57%. The results obtained show that the average compressive strength of soil cement samples increases with an increase in the percentage of fly ash content. The results were compared to samples without additives.
