Question

Quizplus · Accepted Answer

Secondary extraction of petroleum involves the use of solvents, water, or steam to extract additional oil from the reservoir after primary extraction using natural pressure has been completed. This process allows for the extraction of oil to the last drop and can increase the overall yield from a reservoir. It is typically more expensive than primary extraction but less expensive than tertiary extraction methods such as hydraulic fracturing. However, it can still have environmental impacts such as contamination of groundwater if not done properly.
