... modeling and wellbore stability analysis. Borehole failure problems, which are very likly specially when drilling underbalanced, cost the petroleum industry several billions of dollars each year. Prevention of these problems requires clear understanding of the interaction between formation strength...

... drilling practice. These two sections can now be drilled as a single 8½" section. The superior wellbore stability provided by the HPWBM has allowed the mud weight required to stabilize the shales and the evaporites to be reduced significantly. This has had two benefits-the well can be drilled as a single 8...

Gas inflows can pose a problem for stiffened foams. Since stiff foams...

... management of wellbore instability in shales. Abstract The interaction of the drilling fluid with the formation rock is a key factor that determines the time-dependent stability of wellbores in shale formations. The analysis of wellbore stability in shales requires modelling of various coupled...
