In conditions of high temperatures and pressures, reagents-stabilizers widely used in practice undergo chemical change and lose their stabilizing properties, as a result of which the stability and thixotropic functions of clay drilling muds deteriorate, their yield increases and the separation of the suspension occurs with the release of the dispersed phase. Therefore, it is considered promising to use polymineral clay compositions containing palygorskite, which do not require much chemical treatment
