Abstract
This article discusses the problem of incompatibility of drilling conditions associated with the loss of stability of the rocks composing the walls of the wellbore. In the Udmurt Republic, the construction of wells for Devonian development sites is complicated by unstable Saraili sediments, which are the cover of productive horizons. The instability of the Saraili deposits, both during the construction of wells and when drilling sidetracks, can lead to more serious consequences, such as screes and rock falls, sticking of the drilling tool, involuntary cuts, losses of the drilled shaft, and others. These problems can be solved by the technology of capping unstable rocks by using a profile cap while maintaining the nominal diameter of the wellbore.
