they either use one of the folowing types: gamma, beta, alpha depending on the type of place they want to search. they send out the waves and if the signal they receive changes e.g. less signal coming in to the receptor then they know that something is located there and they dig it up to check. the procedure is different in other places but it is similar.

Radioactivity is used in a technique known as radiometric surveying to help locate oil deposits. Certain rock formations in oil reservoirs may contain radioactive elements that emit radiation. By measuring and analyzing the radiation levels of these rocks at the surface level, geologists can infer the presence and potential size of oil deposits underground.

Seismic tomography can help scientists find oil deposits by mapping the subsurface geological structures and identifying potential reservoirs where oil might be trapped. By analyzing the seismic waves that travel through the Earth, scientists can create 3D images of the subsurface which can help pinpoint areas likely to contain oil. This information can guide exploration efforts and increase the chances of discovering oil deposits.
Sulfur can be found in natural environments by looking for volcanic areas, hot springs, and near oil and gas deposits. It can also be found in mineral deposits such as gypsum and pyrite.
Oil Reserves are big and oil deposits are small.
Geologists use various methods such as seismic surveys, gravity and magnetic surveys, and drilling to discover oil and gas deposits. These techniques help geologists to interpret the subsurface geology and locate potential reservoirs where oil and gas may be trapped. Additionally, advances in technology like 3D seismic imaging have improved the accuracy of identifying and extracting oil and gas deposits.
Most of Canada's oil deposits are in northern Alberta
the countries that have deposits of coal and oil have the advantage to have coal to heat up homes, give a warming fire etc, and for countries that have oil deposits can have more petrol, cooking oil :), oil for lamps etc.
Maine does not have any oil deposits-well, at least no discovered oil deposits.
They look for rock formations where oil would be found. They locate those underground rock formations using seismic equipment that bounces a sound wave off rock formations, and back to a receiver. Somewhat the same way that sonar is used to locate a submarine underwater.
Deposits of oil and natural gas.
It is the easiest way to find oil deposits.
