Study Notes
Onshore Drilling
- Used for extracting oil from underground reservoirs on dry land.
- Generally requires lower investments and involves fewer risks compared to offshore drilling.
- The process involves removing water, sand, and salt from crude oil at gathering centers.
- Natural gas is separated from crude oil and sent to a booster station.
- Post-processing, oil is either sent to refineries or oil tankers for shipment.
Offshore Drilling
- Extracts oil deposits beneath the ocean floor using specially designed drilling rigs.
- Rigs can be floating or mounted on sturdy legs that contact the seabed.
- Offshore drilling is more complicated and consumes over 65% of the planned investments before any oil extraction begins.
- High risk of financial loss if wells fail to yield oil.
Drilling Costs and Risks
- The cost to drill an exploratory oil well ranges from 1millionto1 million to 1millionto35 million.
- Expenses are influenced by factors like location (land or underwater), field size, and available geological data.
- Initial drilling requires gathering extensive geological information about subterranean rock structures.
- Uses advanced technology including aerial photography and seismic measurements to determine oil reservoir locations.
Exploration Techniques
- Geoscientists use tools such as seismic technology to visualize rock layers beneath the surface.
- Sound waves help create images of subsurface rocks, revealing potential oil deposits.
- Confirming oil presence requires drilling, a costly gamble with uncertain outcomes.
- Successful identification of oil fields demands collaboration between geoscientists, economists, and financial planners within oil companies.
