Summary:
The produced water (PW) of oil and gas fields is a cost component of their development. The article determines that these waters contain a large number of dissolved chemical components. Components contained in PW have an industrial value. The authors point out that oil and gas companies can extract these waters from the cost component into the revenue component when extracting useful components from the PW. The authors state that geological and economic assessment is needed to use PW as a raw material. This paper proposes a methodological approach to the geological and economic assessment of chemical constituents in PW. The methodology is based on several basic criteria. The work identifies the volumes of extraction of PW, concentrations of chemical components, industrial concentrations, the term of development of the deposit are the main criteria for geological and economic assessment. The paper gives an example of determining the geological reserves of useful components at the Lelyakivskoye deposit. The authors classify these stocks according to the current regulatory documents. The result is that this technique allows these stocks to be converted from code 3.3.3 to code 1.1.2. The authors conclude that the code change should attract investors to the development of PW as a valuable resource.
