Express - methods of calculation for the prediction of the freezing temperatures and unfrozen water and ice content of saline rocks of oil and gas regions of the Yamal Peninsula, that developed using the results of thermodynamic modeling, of data on the chemical composition of water extracts of pore solution, of statistical processing of data in the literature and our own experimental results are proposed. The structure and shape of the calculated ratios are designed as similar to those that are listed in the SP 25.13330.2012 "Soil bases and foundations on permafrost soils," which allows to use them as scientific advice for the establishment of appropriate regional and sectoral regulations. Key Words: saline rocks, freezing temperatures
