Figure 1 (a), (b) and (c) shows the comparison of the seismic data before and after applying sweetness attribute. This attribute is essential to detect areas that are oil and gas prone (sweet spot) and map them on the seismic section. Radovich and Oliveros (1998) stated that oil and gas are probably present when the sweetness values are high. Based on Figure 1, the result after the application of sweetness attribute shows the entire area is mainly consists of minimal sweetness as the light blue colour indicates low amplitude. However, there are a few areas that have presence of dark blue colour which means this is the zone of high amplitude and high sweetness level. Some small spots which are red and yellow in colour are detected in the upper region which indicates the highest amplitude and low frequency of hydrocarbon bearing sand units (Figure 1c). With these small spots of highest amplitude, it is possible that these zones consist of hydrocarbon. Sweetness is very useful in proposing the idea about the hydrocarbon pool.

              This crucial attribute is also known to be used for identify and enhance channel features. Nevertheless, sweetness attribute becomes obsolete when there is low acoustic impedance contrasts between sands and shales. Furthermore, the effectiveness also becomes lesser when both sands and shales are highly interbedded. According to Koson, Chenraj and Choowong (2014), it is a challenge to detect structures like faults and fractures because there are little to no presence of lithology contrasts along the fault planes (Koson, Chenrai and Choowong, 2014). In this figure, no channels can be observed after sweetness has been applied.
