A New Model for Prediction of Wellbore Stability Using the Three Dimensional Hoek–Brown Failure CriterionBy Mohammad Tabaeh Hayavi, Mohammad Abdideh
Abstract: Wellbore stability is one of the crucial issues in oil and gas industries. The issues related to instability of wells, impose significant unwanted costs on drilling operation.The objective of this paper is to present the 3D-wellbore stability prediction models for vertical wellbores. The three dimensional Hoek–Brown strength criterion developed by Zhang and Zhu conjunction with linear poroelastic constitutive model is utilized to develop the models. This models leads to easily …
