ANALYTICAL AND NUMERICAL ANALYSES OF WELLBORE DRILLED IN ELASTOPLASTIC POROUS FORMATIONS
(2012)
The current wellbore stability analyses for analytical solutions are mostly based on the linear elastic or poroelastic theory. The wellbore is regarded as unstable if the determined elastic/poroelastic stresses anywhere ...
INVESTIGATION OF PLUGGING IN ORIFICE, SLOT, AND PORE-THROAT BY FINE PARTICLES
(2010)
orifice- or slot-to-particle-size ratio on flowing fluid conditions and plugging time that lead to particle bridging. It was demonstrated that the critical orifice- or slot-to-particle-size ratio vs. particle-volume-fraction ...
Thermal Effects in Borehole Stability
(2010)
An accurate wellbore stability analysis depends strongly on the state of knowledge of the problem at hand. Almost in all cases, the state of knowledge for wellbore stability analyses is poor. Values of many parameters and ...
