The Reason Why The Gravity Geophysical Exploration Is Becoming Popular

By Lisa Lee


For a long time now, seismic has been the principal method used in the extracting of gas and oil. The logic behind this was the fact that the other options that were available were not well established to do the extraction. Most of that are changing as the technology has paved the way to new methods to be used in the extraction. An example is the gravity geophysical exploration method, which has become popular due to many discoveries being made in its favor. Below are some explanations that will explain that reason that gravity method is becoming popular.

Technology is the one thing that has made it all possible. Technology has done the reading provided by this method easy to read and understand. The results trained before were rough and course as compared to the one that people are getting today. Due to these fine results, gravity is now used alongside seismic or alone as a way of extraction.

In fact, gravity method has grown so much that there some firms that specialize in the gravity field by using the geophysical techniques and blending them with seismic so as to have greater success during the extraction of oil and gas. The reason that is behind this success is the improvement of its data over the years. Due to technology the speed of acquiring data is better and faster.

A scientist has come up with a resolution that is improved thus allowing them to use a small scale and lateral variation that is shallow in the susceptibility and density of magnetic. On the same note, there is a significant role that is played by the hydro-carbonate. Technology has allowed the use of modern gravity to be able to give some results that are more in conjunction with the play of the hydrocarbon.

It is now easy to explore in detail using gravity method in places where the use of seismic alone has not produced any results. The quality of data that is produced by seismic is not uniform in all settings of geology. This is because of the elastic property that is found in the seismic. There is some rock lithology that does not readily produce the acoustic energy. As a result of this, the signals of seismic can be attenuated significantly and in return will offer little seismic imaging below any acoustically challenging horizons.

The tradition methods used in the extraction were not reliable at the interface that is vertical. However with this method, hunters of oil can use it at the interloper between the density that is lateral as well as the place where there is fascinating contrast.

The exploration of oil has become so intense, that there are areas where it cannot be applicable without the use of the gravity process. More explorers are opting to use this method so as to improvement the seismic exploration.

If the technology continues to improve the results that are attained by the gravity method, there will reach a time when it is the only method that is being used. This is because it is accurate, reliable where other methods have failed and most flexible.
