Abstract

Stability of viscoplastic rocks (clays, salts, ice) in the walls of deep wells can be evaluated based on the theory of aging (steady-state creep), for which we propose a proven in practice methodology for determining the stresses on the contour of the wellbore section, radial displacements of points on this contour and their speed.
