| Zusammenfassung |
| The Persian Gulf and its surrounding area are some of the biggest basins and have
a very important role in producing huge amounts of hydrocarbon, and this
potential was evaluated in order to explore the target for geoscientists and petroleum
engineers. Wavelet transform is a useful and applicable technique to reveal
frequency contents of various signals in different branches of science and
especially in petroleum studies. We applied two major capacities of
continuous mode of wavelet transform in seismic investigations. These investigations were operated
to detect reservoir geological structures and some anomalies related to
hydrocarbon to develop and explore new petroleum reservoirs in at least 4 oilfields
in the southwest of Iran. It had been observed that continuous
wavelet transform results show some discontinuities in the location of
faults and are able to display them more clearly than other seismic methods.
Moreover, continuous wavelet transform, utilizing Morlet wavelet, displays
low-frequency shadows on 4 different iso-frequency vertical sections to
identify reservoirs containing gas. By comparing these different figures,
the presence of low-frequency shadows under the reservoir could be seen and
we can relate these variations from anomalies at different frequencies as an
indicator of the presence of hydrocarbons in the target reservoir. |
