The boring log in the Eastern Siberia regions is characterized by the presence of frozen rocks, which causes a number of specific drilling problems. In such conditions, magnesia materials characterized by high expanding capacity are widely used for cementing wells. These materials improve well cementing quality by increasing the areas of complete contact at the rock-cement and cement-casing boundaries. For their effective use, it is important to evaluate the cementing parameters in comparison with the traditionally used Portland cement-based plugging materials. The high quality of the magnesia cement compositions in comparison with Portland cement was justified based on the data obtained from laboratory analysis.
