Innovative technology for the reuse of spent drilling fluids in production well drilling using a hydraulic disperser

Abstract

This article explores an innovative approach to the disposal of used water-based spent drilling fluids (SDF) utilized in the drilling of production wells at uranium deposits, with a case study based on the operations of SD «Inkai». A technological solution is proposed, centered on the use of a hydrodynamic disperser that enables efficient phase separation of drilling fluids, reduction of residual moisture in solid fractions, and the potential for reuse of the liquid phase. The geological and hydrogeological conditions of the deposit are examined in detail, along with the composition and properties of the drilling fluids, challenges associated with their accumulation and disposal, and the legal and regulatory framework of the Republic of Kazakhstan governing drilling waste management. The design of the proposed disperser is presented, the technological process is described, and its advantages over traditional disposal methods are substantiated. The article also analyzes the ecological, operational, and resource-saving aspects related to the implementation of the proposed technology within existing drilling systems.
