oil discovery

The oil was discovered by accident during the drilling of workers in a Pennsylvania state in the United States of America to search for salt. The workers noticed a black, sticky liquid coming out of the salt pits, and causing them problems during the refining process, so a quantity of this substance was collected, and one of the The pharmacists refined it in the laboratory, and this pharmacist was able to obtain a pure amount of this liquid to be used in lighting instead of the wax used in the salt factories.

After the importance of oil was recognized as an energy source as an alternative to coal, the means of oil exploration developed in the United States of America, and production increased from 2,000 barrels in 1859 to about 3,000,000 barrels in 1926.

The world’s oil industry has developed rapidly, and industrialized nations are racing to extend their influence over countries whose oil is available, as oil has become a source of energy worldwide.

Oil detection methods

Despite the ancient discoveries of petroleum, and the development of methods and tools for its detection, the detection processes are still complex and of high financial cost, due to the complexities of the geological structure of the rock layers in which petroleum can be found, there are no fixed models or specific criteria through which Limiting its location in terms of depth, or rock type, in addition to the difficulty of estimating the quantity, whether it is on a commercial level or otherwise.

Modern methods used to detect oil

Stratological Geological Survey

After it was inferred from the presence of petroleum from observations on the surface of the earth, the human being used devices and equipment to photograph the layers of the earth to identify the differences between the rock structures, and to determine the areas by which oil can collect, and depends on the satellites to photograph large areas of the earth and identify the riches Mineral and petroleum ground.

Geophysical survey

It is the practical completion of extracting the required information through the images obtained, through which the structure of the ground layers and the identification of oil reservoirs are identified, and computers helped to quickly extract useful information.

Seismic survey

Information about the geological structure of the site is obtained by making small explosions close to the surface, and through the reflection of the sound of this detonation, geological information is obtained.

Gravitational method

This method depends on the difference in gravity between the rock types due to their different density.
