Finite element analysis of wellbore strengthening
As the world energy demand increases, drilling deeper wells is inevitable. Deeper wells have abnormal pressure zones where the difference between pore pressure and fracture pressure gradient, is very small. Smaller drilling margins make it harder to drill the well and result in high operation costs...
