... 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...

... geomechanical model was the underlying aim of the study. The geomechanical model was constructed through analysis of various offset well data, along with regional geological information, and utilized both elastic and poroelastic models to evaluate the potential impact of UBD on wellbore stability. Hence...

...1. INTRODUCTION Wellbore stability has long been considered one of the most difficult problems in the drilling and completion process. During well test, if the test pressure difference is set unreasonably, it will cause not only the inaccuracy of the productivity evaluation, but also the wellbore...
