a. An oil well in the Nameless Field is producing at a stabilized rate of 600 STB/day at a stabilized bottom-hole flowing pressure of 1800 psi. Analysis of the pressure buildup test data indicates that the pay zone is characterized by a permeability of 120 md and a uniform thickness of 25 ft. The well drains an area of approximately 40 acres. The following additional data is available: rw = 0.25 ft, A = 40 acres Bo= 1.25 bbl/STB, Ho = 2.5 cp Calculate the pressure profile (distribution) and list the pressure drop across 1 ft intervals from rw to 1.25 ft, 4 to 5 ft, 19 to 20 ft, 99 to 100 ft, and 744 to 745 ft.

a. An oil well in the Nameless Field is producing at a stabilized rate of 600 STB/day at a
stabilized bottom-hole flowing pressure of 1800 psi. Analysis of the pressure buildup
test data indicates that the pay zone is characterized by a permeability of 120 md
and a uniform thickness of 25 ft. The well drains an area of approximately 40 acres.
The following additional data is available:
w = 0.25 ft, A = 40 acres
Bo = 1. 25 bbl/STB, Ho = 2. 5 cp
Calculate the pressure profile (distribution) and list the pressure drop across 1 ft
intervals from rw to 1.25 ft, 4 to 5 ft, 19 to 20 ft, 99 to 100 ft, and 744 to 745 ft.
