Abstract
An important step in borehole stability analysis is to estimate a safe and stable mud weight window. A rock failure criterion is required for this purpose. Mud weight windows define the mud program and the number of casing set points thus improving well control and the economy of the drilling project. The aim of this paper is to derive analytical equations for estimating the values of mud pressure corresponding to low and high mud weight shear...
