How deep are most oil wells
Deepwater drilling, or Deep well drilling, is the process of creating holes by drilling rig for oil mining in deep sea. There are approximately 3400 deepwater wells in the Gulf of Mexico with depths greater than 150 meters. Oil wells, after initial separation, produce crude oil and associated (also called casinghead) gas. Gas wells, after initial separation, produce gas well (nonassociated) gas and condensate. The gas from both types of wells is normally processed onshore to produce residue gas (which is mostly methane) and natural gas liquids (NGLs), which The newest wells there are 4900-5725 ft. with some new wells proposed at depths of up to 8200 ft. Oil companies only look deeper when they stop finding oil shallow, as it is more expensive to drill deep. A well 10,000 feet deep requires approximately 50-75 people to operate.
In deep wells, oil-based drilling mud is used because sand to allow a highly conductive passage through which the oil or
Luckily, the oil industry does not have such human obstacles, and drilling deep into the Earth’s crust is instead limited by a different set of circumstances – how deep can the machinery and technology go before the unfathomable heat and pressure renders it inoperable? The World’s Deepest Oil Well Many islanders herd reindeer. And in January, oil crews drilled the world’s longest and deepest extended-reach well, 7.7 miles down into the ground and 7.1 miles out under the ocean. Of these 20,715 wells, 11,522 wells are classed as producing wells that could be producing oil and (or) gas at any depth (above or below 15,000 feet—4,572 m). Nearly as many gas wells exist as dry holes; gas wells (8,600) are more than three times more abundant than oil wells (2,829). To drill a well, a specialized piece of equipment known as a drilling rig bores a hole through many layers of dirt and rock until it reaches the oil and gas reservoir where the oil is held. The size of the borehole differs from well to well, but is generally around 12.5 to 90 centimeters wide. The earliest known oil wells were drilled in China in 347 CE. These wells had depths of up to about 240 metres (790 ft) and were drilled using bits attached to bamboo poles. The oil was burned to evaporate brine and produce salt. By the 10th century, extensive bamboo pipelines connected oil wells with Deepwater drilling, or Deep well drilling, is the process of creating holes by drilling rig for oil mining in deep sea.

You know Many types of drilling fluids are used for drilling for example oil base mud, To drill a 5000m deep well you will really need something bigger than a
The Depth of Oil Wells There's always a lot of chatter about drilling for oil. The environmentalists say we're drilling too far, the oil companies think we're not drilling far enough Over the last six decades, it’s only gotten deeper. In 1949, the earliest year with data available, the average depth of oil wells drilled was 3,635 feet. By 2008, the most recent data available, we were drilling an average of 5,964 feet, Luckily, the oil industry does not have such human obstacles, and drilling deep into the Earth’s crust is instead limited by a different set of circumstances – how deep can the machinery and technology go before the unfathomable heat and pressure renders it inoperable?

Deep beneath this equipment—typically about ½ mile deep—lie one or more layers of Oil flows from the reservoir into the 4- to 8-inch-pipe in the oil well. Most of the oil in Illinois reservoirs came from layers of shale rich in organic matter, 27 Dec 2018 These are oil wells that have undergone the initial process of drilling (i.e., the hole in the ground has been drilled).
