Geophysics is a branch of study that focuses on the earth and its components. This study has been successfully implemented in the practice of mineral exploration and mining and even construction nowadays. Geophysical services help in analyzing, mapping, and interpreting a piece of earth for further investigation.

In this blog, we will discuss geophysics in a broader sense and what it entails. We will go over its various aspects related to mineral extraction to give you an all-around knowledge about Geophysical services. By the end, you will be left with no doubts, so without further ado, let us get started.

What is geophysics?

Geophysics studies the earth and its composition in a non-invasive manner meaning that no sort of drilling, mining, or such is done on the earth. The methods used in the study are usually seismic [which includes the collection of data through reflection, surface waves, and refraction], gravity, magnetic, electromagnetic, electrical, and radioactive.

Geophysics is sometimes also referred to as ‘solid earth geophysics,’ which focuses on specific technical methods of geophysics such as seismology, geothermometry, exploration, engineering, gravity, atmospheric electricity, environmental geophysics, tectonophysics, and terrestrial magnetism.

This branch of geophysics can further be divided into two areas of study, which are: exploration geophysics and global geophysics.

Global geophysics, as the name suggests, relates to studies revolving around the earth’s overall structure and behavior.

On the other hand, exploration geophysics majorly revolves around the use of geological techniques and methods to solve issues pertaining to groundwater, hydrocarbon, geothermal and mineral exploration. This field of study focuses on engineering and environmental interests as compared to the earth as a whole. For more information, you can contact the geophysical services company.

Benefits of geophysics services

Geophysics is a great way to assess the earth’s subsurface due to its various benefits and advantages over other invasive methods of study. Following are some of the major benefits of geophysics services:

  1. Non-invasive

As we mentioned above, geophysics is a non-invasive and non-destructing way of assessing the earth. It is ideal for populated areas such as cities where an environmental or engineering issue can be detected. It is also beneficial for historical and archaeological sites that can be inspected without any damage to them.

  1. Effective

Geophysics does not involve digging into the earth and finding the problem. This way, large areas of the earth’s subsurface in considerably less amount of time.

  1. Cost-effective

Since there is no digging, there are no extra costs for excavation and such. Vast areas of the earth’s subsurface can be examined at lower costs effectively. 

  1. Recognized

Geophysics is not a study that was invented a decade ago. In fact, some of its techniques and methods have been around for over half a century. These techniques are recognized in the market, but they are under-explored when compared to traditional methods.

  1. Far-reaching

Geophysics includes many techniques and methods which can be combined together to solve complex environmental or engineering problems. The more data you have, the easier it becomes to solve the problem.

Different types of geophysical methods used

As we said above, there are different types of geophysical methods and techniques. They can be used separately or combined depending on the needs. Following are some of the major geophysical methods used:

  • Induced polarisation
  • Magnetometer
  • Max-min
  • Spectrometer
  • Geophysical consulting

Application of geophysical methods

Geophysical methods are explored and applied in a systematic way to achieve the best possible results. Following are some of the crucial factors in the application of geophysical methods and strategies:

  1. Preliminary appraisal

The first thing to be done is the preliminary appraisal of the problem at hand. What the problem entails, what is the information known about the site, what is all information required, and what should be the final outcome?

  1. Detection

The next step is the identification of the extent of the coverage required to assess the problem geographically.

  1. Decision

Once there is a clear idea of the scope of the geographical coverage, the next step is to decide which methods and techniques are to be used to get the best outcomes. Not every method is suitable for every problem, so this step needs to be undertaken meticulously in order to gather relevant and viable information.

  1. Assessment

The last step is to assess and oversee how the data and information need to be acquired, interpreted, and presented to solve the issue.

Once all these steps are undertaken with accuracy and the project is approved, the geophysical study can begin.

Conclusion

That was everything you needed to know about geophysics. We discussed the concept of geophysics, its benefits, the types of geophysical methods used, the application of those methods, and how the data collected from those methods and techniques are analyzed and interpreted to solve the problem at hand.
