Based on your plot of mud weight $($ppg$)$ vs depth $(ft),$ draw casing setting of the well and determine the following:

a$.$ Safe mud window.

b$.$ Number of casing, name of each casing and depth of the casing shoe.

c$.$ Determine mud weight used to drill each section and hydrostatic pressure.

Note:

$-$Here you can use Excel software. If you prefer to do manually write your steps in detail.

write the used method of casing setting and explain your steps in detail.
