Given the data below for a vertical well:

${}_H=90$MPa

${}_h$ orientation $isN90E(east-$west$)$

${}_v=88\mathrm{.}2$MPa$($ depth $3213m)$

${}_h=51\mathrm{.}5$MPa

$Pp=P_d=31\mathrm{.}5$MPa

$v_{fr}=0\mathrm{.}25$

$R_w=3\mathrm{.}5$ inches

Calculate the hoop stress around a borehole at $45$ intervals.

Calculate the radial, vertical and hoop stresses away from a borehole $($up to $35$ inches radial distance$).$
