CFD SIMULATION OF SURGE AND SWAB PRESURES IN CONCENTRIC AND ECCENTRIC ANNULI USING POWER-LAW FLUID

In deepwater exploration, wellbore pressure stability must be maintained to avoid a catastrophic accident such as blowout. Accounting for the factors contributing to wellbore pressure is beneficial to ensuring the stability of the wellbore. In this study, a Computational Fluid Dynamic (CFD) is used...
