Paper presented at the International Geomechanics Symposium, October 30–November 2, 2023
Paper Number: ARMA-IGS-2023-0145
... of the existing literature on wellbore stability analysis in fractured formations focuses on the coupled effects of fluid flow and deformation, and the impact of three-dimensional natural fracture characteristics (roughness, dip angle, etc.) on wellbore instability is not yet closely examined, which may yield...

Paper Number: ARMA-IGS-2023-0018
... Abstract Drilling a wellbore into a clastic reservoir exhibits complex rock behavior, including plastic deformation and yield zone development, which can affect wellbore stability and hydrocarbon production efficiency. Elastoplastic modeling methods have been increasingly used to simulate...

Paper presented at the International Geomechanics Symposium, November 7–10, 2022
Paper Number: ARMA-IGS-2022-001
.... ABSTRACT Wellbore stability modeling has been known in the oil and gas industry and academia for a long time. The instability-related issues significantly impact field developments, especially in complex deep reservoirs. This instability can substantially jeopardize the drilling objectives, leading to poor...

Paper Number: ARMA-IGS-2022-006
... Abstract The dynamic wellbore pressure induced by the frictional pressure loss and swab/surge pressure may lead to wellbore instability in the process of drilling. However, the traditional wellbore stability analysis assumes a steady wellbore pressure, rather than a dynamic wellbore pressure...

... 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...

Paper Number: ARMA-IGS-20-060
...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...
