Question No $2($MLO$-2)(60$ marks$)$

Propose the most economical casing program for any one of the section in the wellbore using Halliburton Landmark Software. Assume the data by yourself to be used in the analysis. The pore pressure and fracture pressure gradients with respect to depth is given in the table below.
