SPATIOTEMPORAL DISTRIBUTION OF THE CONGLOMERATE RESERVOIR JATIBARANG FORMATION, MELANDONG FIELD, NORTH-WEST JAVA BASIN, INDONESIA

Subsurface mapping of the distribution reservoir is essential to be conducted in order minimize many risks such as financial losses and also increase profit from hydrocarbon production. This research was on Jatibarang conglomerate Melandong Field, North West Java Basin, Indonesia. There are three objectives this study which perform elastic impedance (EI) seismic inversion using available 3D data, determine most suitable angle for map spatiotemporal Formation field, basin, EI selected ranging near stack (5º-15º) far (20º-30º). Results show that can help detecting lithology within target zone. Angle 5º considered best studied data indicated by a correlation value 0.65. Moreover, angles 15º 10º less reliable shown their 0.6 0.56, respectively. These results expected provide some new insights into reservoir, exploration, exploitation, development oil gas fields
