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 ...

Simulation of Modified Dual Gradient Drilling System to Drill Deepwater and Ultra-Deepwater Wells [PDF]

One of the main challenges in deepwater subsea drilling is the narrow operational mud weight window between pore pressure and fracture gradient; as water depth increases so does the complexity of maintaining this window.
