How Do Oil and Gas Companies Conduct Oil Exploration?

Exploration plays a vital role in keeping the oil and gas industry running. Due to the increasing demands of oil in many countries, exploring oil and gas reserves is also becoming more essential.

However, there are several ways to conduct oil exploration. This blog post talks about the three methods used for exploring oil reserves.

Surface Methods

There are two phases in oil and gas exploration through surface methods.

The first phase involves analyzing the surface and determining if it can be used as oil reserve. This involves classifying the rocks if it’s sedimentary.

The second phase is to determine if there are oil seeps on the surface of the earth. If the oil underground is not leaking, that means large deposits are present.

Magnetic Surveys

Magnetic surveys involve the use of an instrument called a gravimeter. They are used to assess the amount of oil and gas deposits underground.

Another instrument used is the magnetometers. Together, these two instruments can assess and map the anomalies and measurements of the site.

Seismographic Methods

The problem with magnetic surveys and surface methods is that it cannot analyze small areas.

That’s why seismographic methods are also used through the sound waves, producing detailed images of the underground rock formations, though there are techniques that can lead to damage when placing the gadgets that makes this method possible.

Exploring oil reserves is not as simple as some people think. Although there are many methods in exploring oil reserves, each one serves different purpose. If one is not suited for the job, the other is used, and so on.
