Oil companies and private firms employ geologists to locate new oil reserves. Geologists examine terrain and surface rocks in satellite images, and also examine the land in person to determine soil and rock types that are indicative of possible oil deposits. Seismic surveys of these promising areas can then confirm if there are oil 'traps,' where the oil is sandwiched between layers of impermeable rock.

How many oil fields in the world today?

There are thousands of oil fields around the world, with varying sizes and production capacities. The exact number is difficult to pinpoint as new fields are discovered and developed, while others may become inactive or depleted over time. Major oil-producing countries like the United States, Saudi Arabia, Russia, and Canada have numerous oil fields within their territories.


What are some alternative fields?

Some alternative fields to explore could be renewable energy, virtual reality and augmented reality, data science and analytics, sustainable agriculture, and artificial intelligence. These fields are increasingly growing and offer diverse opportunities for those looking to explore new career paths.


How does ocean drilling provide evidence for plate tectonics?

Ocean drilling provides evidence for plate tectonics through the study of rock samples retrieved from the ocean floor. By analyzing the age and composition of these rocks, scientists can identify patterns of seafloor spreading and subduction, supporting the theory of plate tectonics. Additionally, the presence of magnetic striping on the ocean floor provides further evidence for the movement of tectonic plates over time. Overall, ocean drilling plays a crucial role in understanding the dynamic processes of the Earth's lithosphere and the movement of tectonic plates.


How are deep underground deposits of oil and natural gas are located?

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.

What are the pros and cons of self-operate exploration drilling machines and Contract Drilling Companies in the mining industry?

In the mining industry most companies cannot afford the cost of maintaining the drilling equipment nor infrastructure required to do inhouse exploration. Self-operated exploration drilling requires the company to have and H/R staff which can higher high caliber people and then attach them to the corporate employment package for the long term. Most self-operated exploration drilling machines cost 2 times as much as contract drilling companies that can distribute the costs and employment agreements over multiple footage projects and locations. Contract Drilling companies stay abreast of new developments in the industry and maintain records to track costs thus arriving at the most economical footage results available for the formations being drilled. (no hidden cost) Self-operate exploration drilling have costs that are ignored and/or written off in other areas of the corporate structure. ie Repairs, fuel, moves, administration. Pro of Self-operated exploration drilling are that the company attains the information on the ore bodies in a more timely manner to make mining development decisions on and operating mine. Self-operated exploration drilling and contract drilling is similar to large mining company keeping staff to do raw exploration- they don't. The large mining companies invest in the junior exploration companies to find new ore bodies which allows them to have experience people looking for ore bodies and managing them selves vs. maintaining a large costly exploration staff. The juniors use contractors because they cannot afford the large capitalization for the drilling equipment and tooling to do small exploration projects to see if they have and ore body. If the junior finds and ore body the large mining company will fund the drilling project for a percentage of the property or will buy out the juniors stock to own the property. The economics of the property will dictated the pros and cons of in-house drilling or contract drilling. It may come down to the risk involved in the ore body involved.

How do you select a new drilling rig?

It depends on what exactly you are trying to do. The depth you want to drill to; the depth of water you are working in; what type of media you are trying to drill through; the location of the job. There are many types of rig availible; when you know what you want to then you would contact one of the (many) drilling companies who would explain the best options for you.

Where can you find an oil rigs correspondence school?

I do not think there is an actual correspondence school for Oil Rigs. Or at least I have never heard of one. There are, however, some online resources and correspondence courses for certain aspects of the drilling operation such as Blow Out Prevention, diesel mechanics, and electrical training since most of the new rigs are essentially electrical with power generated with diesel motors. There are, however, several companies that are now trying to provide training for working on drilling rigs. Nabor's Drilling is one example, with at least one school in Casper Wyoming.


What benefits do you have putting oil riggs in the water?

Offshore drilling rigs can reach deep oil reservoirs that lie below the sea floor. Initially, our oil came from discoveries on land, however in search of new oil fields, it was necessary to drill wells offshore. Oil companies have made very large oil discoveries in deep water regions in the Gulf of Mexico. See related link.
