See related link which is only related to US wells. The depth at which hydrocarbon deposits are found varies greatly. Very shallow deposits of less than 100 feet were found in the early days of exploration. Today, it is not uncommon to drill to 10,000 feet or more, although the US average depth is 5600 ft for oil and 5700 ft for natural gas. We have the technology to drill to 15,000 to 20,000 feet and if conditions are right even deeper. However, the high temperatures may preclude finding oil. The high cost of drilling may make development uncommercial unless a very large deposit is found. The challenges today are not only to find new deposits at deeper depths in the ground, but to drill wells and erect production platforms in deep water. The deepest well was drilled to 37,000 ft in Russia in 2003.

MaxineDeep underground deposits of oil and natural gas are located using various methods such as seismic imaging, well logging, and exploratory drilling. Seismic imaging involves sending sound waves into the ground and analyzing the reflections to create a picture of subsurface formations. Well logging involves examining rock samples and measurements taken from drilling operations. Exploratory drilling is done to confirm the presence and quality of oil and gas deposits.

What type of mining in which passageways are dug underground to reach the ore?
The type of mining in which passageways are dug underground to reach the ore is called underground mining. It involves creating tunnels and shafts to access mineral deposits located deep underground.
Type of mining where passageways are dug underground to reach the ore?
This type of mining is called underground mining. Miners access the ore through tunnels and shafts dug beneath the surface of the Earth. It is often used when the ore deposits are located deep underground.
What is subsurface mining?
Subsurface mining is a method used to extract minerals and ores that are located deep underground. It involves creating tunnels and shafts to access the deposits and extract the resources. This method is often used when the mineral deposits are too deep to be reached with surface mining techniques.
Which type mining be used to extract a vein of ore form deep underground?
The type of mining used to extract a vein of ore from deep underground is known as underground mining. This method involves creating tunnels and shafts to access and extract mineral deposits located deep within the earth. The two main types of underground mining are called shaft mining and drift mining.
Why do we use underground mining?
Underground mining is used to extract valuable minerals or ores located deep beneath the Earth's surface. It is often the only feasible method to access mineral deposits when they are located too deep or when surface mining methods are not suitable due to environmental concerns or safety reasons. Underground mining also allows for the extraction of minerals in a more controlled and efficient manner.
