Anisotropic Porochemoelectroelastic Solution for Inclined Wellbores with Applications to Operations in Unconventional Shale Plays
In this work, the porochemoelectroelastic theory is applied to analyze instability problems of an inclined wellbore drilled in the laminated and charged saturated chemically active shale formations. Numerical example is given for wellbore drilling in the Woodford gas shale formation. The analysis shows that ignoring either the porochemoelectroelastic effects or the formation anisotropy can lead to inaccurate predictions of potential wellbore integrity problems.
