Oil well - Wikipedia
An oil well is a drillhole boring in Earth that is designed to bring petroleum oil hydrocarbons to the surface. Usually some natural gas is released as associated petroleum gas along with the oil. A well that is designed to produce only gas may be termed a gas well.
Drilling, Completing, and Producing from Oil and Natural Gas Wells
Once a suitable well location has been identified, permitted, and leased, the next steps for oil and natural gas development are drilling, completion, and production: Drilling typically takes about 50-60 days.

U.S. Oil and Natural Gas Wells by Production Rate - U.S. Energy ...
Exploring how U.S. oil and natural gas wells have changed provides deeper insight into this rapid growth. In this report, we present data on the distribution of wells by size and technology and analyze emerging trends.
Petroleum production - Drilling, Refining, Extraction | Britannica
During the mid- to late 20th century, rotary drilling became the preferred penetration method for oil and gas wells. In this method a special tool, the drill bit, rotates while bearing down on the bottom of the well, thus gouging and chipping its way downward. Probably the greatest advantage of rotary drilling over cable tooling is that the ...
Oil well - Energy Education
An oil well is a hole dug into the Earth that serves the purpose of bringing oil or other hydrocarbons - such as natural gas - to the surface. Oil wells almost always produce some natural gas and frequently bring water up with the other petroleum products.
Drilling Technology - American Oil & Gas Historical Society
Drilling or “making hole” began long before crude oil or natural gas were anything more than flammable curiosities found seeping from the ground. For centuries, digging by hand or shovel were the best technologies that existed to pry into the earth’s secrets. Oil provided a …
