A Complete Rigorous Semianalytical Graphical Solution for the Undrained Wellbore Stability Problem in Elastoplastic Hoek–Brown Rock under Nonhydrostatic In Situ Stresses
Abstract
Abstract This work develops a rigorous semianalytical solution for evaluating the stability
of an impermeable wellbore in a rock formation that obeys the Hoek–Brown failure criterion
in a nonhydrostatic stress field. The solution expands a previous ...
