Determine the total cost ($) of drilling from 9,500 ft. to 12,500 ft. Assume that you start drilling with a new bit at 9,500 ft. Other relevant data are given as follows:

Final Well depth = 14,500 ft.

Casing Settings Depths = 750 ft, 6500 ft, 9500 ft, 12,500 ft, 14,500 ft.

Rig operational cost = $24,000/day.

Crew: Can handle a single pipe connection in average time of 2.0 minutes.

Trip time (hrs) = 0.001 * D_out

Bits:

Size (inch)	Average Life (hours)	Cost
24	35	$10,000
17 1/2	30	$14,500
12 1/4	25	$13,500
8 5/8	20	$12,500
6 1/4	20	$10,000
