Technical and economic background for siting production of well-killing liquid at oil fields

Abstract

Modern development of technology allows for significant reduction of operation costs in many processes, including production of well-killing fluid. Efficiency of manufacturers and prerequisites of its economic profitability are a composite of lower operating costs, application of innovative materials with lower prices together with the basic technologies of labor costs optimization. This paper proposes introducing new approaches in implementing removal of salt from associated water. A feature of this method is evaporation of salts from solution by thermocompressive vacuum evaporation. A project for formation water treatment assumes building a plant for a complex solution of the salt removal problem. One of the main objectives of the project is to achieve annual turnover of 30,000 t of dietary salt, as well as production of well-killing liquid in the amount of 40,000 t per year. The environmental component of the project it its important feature: first, the load on the water treatment system is lowered, as is the risk of unauthorized spills; second, the quality of produced dietary salt meets the requirements of GOST 13830-91 and SanPin 42-123-4089-91. Locations near the oil fields will allow achieving all the aforementioned objectives. The project will be profitable and advantageous in technological, economic and environmental sense. The optimal solution for import substitution: reduction of electricity costs for water transportation. Sale of new products and reduction of environmental load will also allow diversifying the industrial infrastructure of the oil-and-gas-producing region at the late stages of oil fields development and will make it possible to use the released labor force and energy facilities.
