Tips On What Goes Into The Production Of Seismic Drilling Products

By Kathryn Neal


Seismic drilling can be referred to by several terms, including shot drilling, and is used in the process of surveys for geological purposes and seismic drilling products. The purpose of this type of exploration is to get an idea of the earth's underlying surface, in order to find out if there are any valuable substances in the vicinity. The survey will also reveal if it is possible to reach the material underneath, by way of drilling, and can provide valuable information about subsurface formations that can be used by scientists for several purposes. Oil and gas are often found by the use of seismic surveys.

The shot hole exploration equipment is used in the first part of the process, and ensure that a sizable hole is created for the insertion of explosives. The holes can be drilled to various depths, depending on what is required. The drills used are not solidly constructed in one place, as many holes need to be dug, and also because of the use of explosives in the survey process.

Explosives are then carefully used to cause vibrations. Their vibrations help the seismologists to determine the location of the minerals or other forms of deposits below the earth's surface, because they bounce off of the substances. The movements of the vibrations are quite easily traced with the use of seismic devices. The shot hole exploration team consists of various experts, including those of explosives and geological formations.

Not just anyone can complete shot hole exploration work. Special permission is required before the work can begin. This is because of the impact that it may have on the surrounding environment, such as the animals and plants of the area, and even the people who live nearby the area. To obtain permission details are needed such as the reason for the work.

Especially because explosives are involved, the whole team of survey workers should follow safety rules. There are always certain procedures in place to ensure the safety of the workers. Certain personnel may also be in charge of cleaning up the site after the drilling and explosive work is done.

When exploration detects a possible underground resource, the company may require some test wells to be sunken, before the drilling of actual wells. This could save some money should the findings not be of any use. In general, whether the site proves to have valuable resources or not, the process of shot hole exploration is expensive. Time and money should therefore be saved wherever possible. Sometimes the minerals that are found are not within reach of exploration equipment, or they will be impossible to remove for other reasons.

Over the years there have been many ways of finding resources underground. The use of explosives to shake the ground and provide wave recordings was referred to as land-side seismology, while Palmieri's seismology involved the use of electricity and mercury to provide findings. Nowadays, geological seismology has become more technical, and is more efficiently performed.

Seismic readings are necessary for information regarding geological formations, but when explosives are used, the land of the work site is destroyed, along with the fauna and flora that were there. Methods that don't use explosives are nowadays preferred, if possible, such as thumper trucks and air guns. These two methods also create vibrations, but do not destroy wildlife. Seismic drilling products should not be at the detriment of the environment even if it's for a very good reason.
