answer is in blackQ$3$:

It has been decided to sidetrack a well from $1500ft.$ The sidetrack will be an $S-$shape profile with

the following specifications:

Target Coordinates:

Surface Coordinates:

TVD of Bottom of Hole:

Build up Rate:

Drop off rate:

$1300$ftE&$-1600ftN$

$-2300$ftE&$1000ftN$

$12000ft.$

$1\mathrm{.}5$ per $100ft.$

$2\mathrm{.}5$ per $100ft$

Calculate the following:

a$)$ Total departure and azimuth

b$)$ Drift angle of the well.

c$)$ TVD$,$ MD$,$ and horizontal departure at the end of buildup section

d$)$ MD and horizontal departure at the TVD midpoint of buildup section

e$)$ TVD$,$ MD$,$ and horizontal departure at the end of tangent section

f$)$ TVD and horizontal departure at the midpoint MD of tangent section

g$)$ MD and horizontal departure at the TVD midpoint of drop off section

h$)$ Total measured depth to the target.
