Abstract: In this article, the method of drilling mud processing using the PACS and PACS-T (thermally stabilized) systems, as well as the results of their field tests, are highlighted and considered in detail. Inhibited solutions after prolonged stoppages (for the period of geophysical research and others) restoration of the circulation of the solution is carried out intermittently after the drilling tool is lowered into the cased part of the borehole (casing shoe). This causes the sedimentation stability of the solution for a long time and reduces the likelihood of the drill string being seized due to the retention of the suspended state of barite particles and drilled rock. When using the PACS and PACS-T (thermostabilized) systems on the oil and gas areas of Turkmenistan, in sections containing clay rocks, the narrowing of the borehole, collapses and tacks of drilling tools stopped.
