dc.description.abstract | The Low Frequency Passive Seismic (LFPS) method is a geophysical technique used to detect
and analyze subsurface structures by utilizing low-frequency natural seismic waves. This study
was conducted in the vicinity of area X to identify the presence of hydrocarbon reservoirs
beneath the surface. The method involves analyzing potential fluid reservoirs by examining
the maximum amplitude of the Power Spectral Density (PSD) and assessing parameters such
as depth and the Vertical to Horizontal Spectral Ratio (VHSR). This approach helps to identify
areas with exploration potential. The LFPS method uses natural seismic waves, in the form of
microtremor measurements, as a data source. The fundamental principle of LFPS is to record
and analyze ground vibrations, or microtremors, produced by various natural sources such as
ocean waves and volcanic activity, using Fourier transform to process the data in V/H
(Vertical/Horizontal) analysis. The results of this study indicate that by analyzing all obtained
attribute parameters, such as the maximum spectrum PSD value patterns, particularly the depth
parameter or PSD(Z), the V/H ratio curves, and the distribution maps of the maximum PSD(Z)
values, along with reference well data and maximum V/H ratio values, there is potential for
fluid reservoirs in two zones: Zone A and Zone B. Zone A exhibits higher Z and V/H amplitude
values compared to Zone B. Zone A is located at points X-13, X-14, X-18, X-23, X-28, X-29,
and X-33, while Zone B is at points X-39 and X-44. | en_US |
