... distribution model and weak plane strength criterion have been used to establish the wellbore stability model, which considers the influence of weak plane and chemical effect. Investigation on influence factors of collapse pressure is conducted through the established model. The results show that the existence...

... characteristics (grain size, permeability, pore fluid viscosity). The chosen inputs are based on average geomechanical parameters in the sand, unlike the 1D elastic methods where the MW recommendations vary along the logged portion of the well trajectory. In the 1D model, the collapse pressure (MW) computed over...
