| In
directional and in underbalanced wells, borehole stability can be
a critical problem. WELLSTAB-Plus uses a linear mechanical/chemical
poro-elastic model to analyze stresses and stability in deviated wellbores.
Two Linear Elastic Models with or without fluid flow are used to predict
stability of the borehole and the range of stable borehole pressures
or mud weights. Advanced graphical tools allow analyzing the impact of changes in critical parameters.

Input data describing the wellbore and formations are easy to enter.
Several utilities are provided to help estimate pore pressures, vertical/horizontal in-situ stresses, and rock mechanical properties.
Wellbore stability results are displayed in six graph and table windows that can be easily reviewed. |
