Real – Time Geomechanics: Applications to Deepwater Drilling
, 2010 Lithologies under deepwater conditions usually show relatively reduced effective stress, due to the reduced lithostatic column. This translates into relatively narrow mud weight windows, driven mainly by shear failure or pore pressure in overpressured ...
