Wu This study u ses sequence stratigraphic concept s (Haq et al., 1987, Science) to analyze the well log data and to recognize the sequence boundaries. Correlation 1 of these sequence boundar ies help ed to identify the ( T Y- 1) characteristics of potential stratigraphic traps in western Taiwan. Take the well TY-1 for example, the Bazhangxi (b asal tr an sgr essiv e sandstone penetrated by this well showed a deposition san d) (r etr ogr a d at i on ) of basal tran sgressive sand in Tran sgressive Systems (Tr an sgr e s siv e Sy st em s Tr a ct , Tract (TST).
