Question: As conventional sources of crude oil are depleted, unconventional sources such as oil sands (also known as tar sands) are being utilized. Oils sands contain bitumen, which can be processed into a synthetic crude oil. A region of boreal forest in Alberta, Canada, that covers a deposit of oil sands will be cut and removed during the process of bitumen extraction. It is estimated that the deposit contains 73 billion barrels of recoverable bitumen. The rate of extraction from the deposit will be approximately 1 million barrels of bitumen per day. 1. Assuming the above extraction rate, calculate how many days will be needed to extract the recoverable volume of bitumen from the oil sands. a. What units should the answer be in? b. Which number relationship has those units? c. What are the other units given in the question? d. How are those units expressed in the paragraph?
1. To calculate the number of days needed to extract the recoverable volume of bitumen from the oil sands, you will need to divide the total volume of recoverable bitumen (73 billion barrels) by the rate of extraction (1 million barrels per day). a. The answer should be in units of days. b. The number relationship with these units would be the time required for extraction, which is calculated by dividing the total volume (in barrels) by the rate of extraction (in barrels per day). c. The other units given in question are barrels, billion barrels, and million barrels per day. d. These units are expressed in the paragraph as follows: - Barrels: This is the unit of volume for the bitumen that can be extracted. This unit is also used to express the rate of extraction, per day. - Billion barrels: This is the unit used to express the total volume of recoverable bitumen in the oil sands. - Million barrels per day: This is the unit used to express the rate at which bitumen can be extracted from the oil sands.
