After a lengthy series of court cases, The United States District Court for the Eastern District of Louisiana officially ruled that 4.0 million barrels of oil were released from the drill pipe during the incident. Was your calculation of the total barrels discharged in relative agreement with this ruling? Explain your reasoning.

Exercise 2: The Deepwater Horizon Incident
Data Sheet
Background Information Needed to Complete the Assignment:
⦁ Diameter of the Deepwater Horizon drill pipe: 20 inches
⦁ Average rate of oil moving through the pipe: 20 inches/second
⦁ Area of a circle: πr2 (pi times r squared), where π = 3.14159 and r = the radius of the circle (1/2 of the diameter)
⦁ Calculate the interior area of the drill pipe using the formula for the area of a circle. Your answer will be in square inches (in2). Show your work below and record your answer in Table 2.
⦁ Calculate the volume of oil escaping the pipe every second by multiplying the interior area of the drill pipe (you calculated above) by the average rate of oil moving through the pipe. Your answer will be in cubic inches per second (in3/s). Show your work below and record your answer in Table 2.
⦁ Calculate the volume of oil escaping the pipe each minute by converting your previous answer to cubic inches per minute (in3/min). Remember, there are 60 seconds in 1 minute. Show your work below and record your answer in Table 2.
⦁ Calculate the volume of oil escaping the pipe each hour by converting your previous answer to cubic inches per hour (in3/hr). Remember, there are 60 minutes in 1 hour. Show your work below and record your answer in Table 2.
⦁ Calculate the volume of oil escaping the pipe per day by converting your previous answer to cubic inches per day (in3/day). Remember, there are 24 hours in 1 day. Show your work and record your answer in Table 2.
⦁ Convert the volume of oil escaping the pipe per day from cubic inches per day (in3/day) to cubic feet per day (ft3/day). The conversion factor is 1 in3 = 0.000579 ft3. Show your work below and record your answer in Table 2.
⦁ Convert the volume of oil escaping the piper per day from cubic feet per day (ft3/day) to barrels per day (bbl/day). The conversion factor is 1 barrel = 5.61 ft3. Show your work below and record your answer in Table 2.
⦁ Find the total barrels of oil discharged during the incident by multiplying the barrels of oil escaping the pipe per day by the total length of time the pipe leaked (86 days). Show your work below and record your answer in Table 2.
⦁ Convert the total barrels of oil (bbl) discharged during the incident to total gallons of oil (gal) discharged during the incident. There are 42 gallons in 1 barrel of oil. Show your work below and record your answer in Table 2.

Barrels of Oil Escaping the Pipe Per Day (bbl/day):
Total Barrels of Oil Discharged (bbl):
Total Gallons of Oil Discharged (gal):

Exercise 2 Post-Lab Questions

⦁ After a lengthy series of court cases, The United States District Court for the Eastern District of Louisiana officially ruled that 4.0 million barrels of oil were released from the drill pipe during the incident. Was your calculation of the total barrels discharged in relative agreement with this ruling? Explain your reasoning.

⦁ Calculate the percent error of your determination of the total barrels released (compared to the official court ruling). The equation for percent error is below. Show your work.

⦁ The Deepwater Horizon blowout and spill was a human, economic, and environmental disaster. On a fundamental level, our demand for energy is driving the oil and gas industry into more complex and unknown territory, where the consequences of mistakes and accidents become far greater. By drilling in such areas, the energy industry has determined that the monetary rewards of drilling far outweigh the human and environmental risks. Do you agree with this assessment? Explain your reasoning.
