This study mainly focuses on updating the geological map at Kampung Buluh, Permaisuri, Setiu Terengganu within area of 25, 000 km² with coordinate 5 32’ 35. 54” N, 102 45’ 23.87” E and involve seismic interpretation of Kapal Field, Terengganu offshore using 2-Dimensional data obtained from PETRONAS. The geological research includes mapping, petrography, lithology, stratigraphy, and geomorphology had been done at Kampung Buluh, Setiu, Terengganu. The geological mapping is significant for identifying the lithology of rock and analysis of geological structure or formation that occurred in the study area. Based on rock sample observation and further petrographic analysis, the lithology at the study area could be determine. Moreover, the geological mapping conducted at Kampung Buluh are believed to exist under Sungai Peris Formation, thus this study will help to identify the formation of Kampung Buluh. In addition, this research is helpful since no prior studies or geological research have been conducted to determine the kind of rock, geological formation, geomorphology, or lithology present in Kampung Buluh. Referring to the previous research, the Setiu area was dominated by the carboniferous age of rock formation which is around 359 to 299 million years ago. Based on detail analysis of the rock, the area of Kampung Buluh consists of slate, phyllite, schist, sandstone, and quartzite. Based on this finding and sample analysis, the region comprised the meta-sedimentary rock. As for the second objective, the seismic interpretation using secondary data had been conducted as it significant to interpret the hydrocarbon potential based on reflection data obtained
