Forecast of calcium, barium and strontium sulfate salt deposits during development of the oil and gas condensate field of the Nepa-Botuobinskaya anteclise (Eastern Siberia)

The paper presents a forecast of calcium, barium and strontium sulfate salt deposition for the Nepa-Botuoba oil and gas condensate field. The salt deposition forecast was made using both analytical calculations by the Oddo and Thomson method and thermodynamic modeling. As a result of determining the amount of sulfate salts that could precipitate, it was established how much the permeability of the bottomhole formation zone and the oil production rate of producing wells could potentially decrease due to the precipitation of gypsum, barite and celestine.
