Classification of creaming mixtures for elimination of zones of drilling mudids

The drilling process is often complicated by all sorts of geological complications that provoke instability of rocks. In such cases, additional time and material costs arise. When drilling oil wells, the stability of rocks is directly influenced by geological features. As well as the selected drilling technique. In the article we will consider information regarding the necessary conditions for the occurrence of absorption, as well as the categories of their intensity. In addition, important nuances of measures aimed at preventing and eliminating the consequences caused by complications will be considered. A classification of cement mixtures that are used to eliminate lost circulation zones of drilling fluid is also presented.
