Until now, petroleum is one of the most important sources of energy for human life. Based on CNBC, OPEC estimates that world petroleum consumption will grow by 7.3 barrel per day. However, the scarcity of petroleum is not only due to the factor of the need for petroleum but also because of the difficulties in finding the source of petroleum. Petroleum that is usually detected through sound reflection is only able to be captured with 2-dimensional waves. This causes the images obtained by the computer to be less clear. Moreover, to do this petroleum searching requires a lot of computers and definitely requires a large cost. The frequency obtained can change according to the waves which makes it increasingly difficult for petroleum companies to solve the wave. However, at the beginning of the 21st century, the Helmholtz equation was solved which was able to overcome this problem. The Helmholtz equation can solve problems in the search for petroleum sources by detecti...
