Oil is obtained from the ground primarily through the process of drilling wells into underground reservoirs.
The Basic Process of Oil Extraction
To access the valuable oil reserves located deep within the Earth, oil companies follow a specific procedure involving drilling.
Based on the provided information, the steps involved include:
- An oil company must first drill down to where the oil is located.
- Before drilling begins, a rig (likely a correction from "rake" as mentioned in the reference) is set up. This structure is essential to support the drilling equipment and process.
- Next, a well is drilled into the ground. This well acts as a pathway down to the oil-bearing rock formation.
- Drilling continues until the oil is reached. Once the well bore intersects the oil reservoir, the oil can potentially flow up the well.
- This method is used for accessing oil fields, whether they are located on land or in the sea.
This drilling process creates a connection between the surface and the underground oil reservoir, allowing the oil to be brought up for collection and processing.
