Minimizing Drill-String-Induced Wellbore Instability

Middle East Oil, Gas and Geosciences Show, 2023
Abstract Objective/Scope Every year the petroleum industry spends more than an estimated $6 billion in mitigating wellbore instabilities that account for nearly half of the drilling-related NPT (non-productive time). Researchers believe wellbore instability problems occur primarily due to physical and
