Calculation of safe drilling mud density window for shale formation by considering chemo-poro-mechanical coupling effect
It is difficult to define safe drilling mud density window for shale sections. To solve this problem, the general Biot effective stress principle developed by Heidug and Wong was modified. The Weibull statistical model was used to characterize the hydration strain-related strength damage. Considerin...
