The Techniques Of Oil And Gas Exploration

By Kevin Jackson


Oil and gas are the main components used in gearing the economy of a country. This is because it is highly used in almost all aspects of the economy. Almost 80% of the industries use these products making them heavily used. Nevertheless, these resources can be exhausted and therefore, mining companies have to keep up with the demand and continue looking for more of these resources. Discussed below are some of the ways of oil and gas exploration.

The investigation to find out the presence of the natural resources is important because it is expensive to mine. Companies must be sure that there is something that is worth mining in the area. Mining without investigation can cause a lot of losses for companies. It is because they might end up getting nothing in the area which is a loss and has serious environmental effects to the area.

There are a lot of considerations that the explorers put to place. They are important because they will ensure that the companies only go to the area where they will get the products. The explorers must survey the area to ensure that they have cap rock, source rock, and the reservoir. The survey method is called seismic survey which involves the knowing the levels of the various factors for mining.

One of the most used methods for mining is the seismic survey. As its name suggests, this method uses sound to get the information about the area that is a potential for energy resources. It is mostly used in the seas and oceans because they are deep for divers to reach the floor. The information is recorded using a geophone. It is important for the companies to use this technology to ensure that they know how deep the wells are from the surface.

Another method that is used to measure the areas that can be mined is known as an offshore survey. This method uses bubbles. The bubbles are busted on the surface of the rock that has the natural resource. The sound then travels through the rock which is then recorded and measured. The unique sound that the rock will produce sometimes may indicate the availability of the resources being searched.

Also, some explorations may employ the use of gravimeters and the magnetometers. These are used to measure and assess the earth gravity pull on the surface. Again, geochemical prospecting entails measuring of the natural gases by use of the high-tech machines.

For the mining to be effective, the geologists have to assess the structure of the exploration site. They do this through a method called the remote sensing. To start with, an aerial photograph is taken to map the proposed area. This helps to reveal some important details like the vegetation type, soil, minerals and other features.

If the explorers do not have the necessary information about the area, it can be difficult to know where to get the resources. For this case, they usually do a wildcat welling. It is the only way they can get the necessary information about where to get the resources from.
