Rotary drilling is the most widely used method in the industry. A rotating drill bit cuts through rock layers while drilling fluids help cool the equipment and remove debris.
This technique is effective for both shallow and deep wells.
Directional Drilling
Directional drilling allows operators to steer the wellbore at various angles instead of drilling straight down.
This technique is particularly useful for accessing oil reservoirs located beneath obstacles like cities, bodies of water, or environmentally sensitive areas.
Horizontal Drilling
An advanced form of directional drilling, horizontal drilling involves turning the drill bit sideways to extract oil from thin, widespread reservoirs.
It is widely used in fracking and offshore drilling, as it increases contact with oil-rich rock formations.
Percussion Drilling
One of the earliest drilling techniques, percussion drilling involves repeatedly striking the ground with a heavy tool to break through rock.
While largely outdated, it played a significant role in the history of oil drilling.
Onshore vs. Offshore Drilling
Onshore drilling is conducted on land and is generally more accessible and cost-effective.
Offshore drilling, performed in oceans and seas, requires specialized equipment and platforms to withstand harsh marine conditions.
