Abstract

Rift-related tectonics control the deep stratigraphy and many of the petroleum systems in the offshore West Natuna Basin, Indonesia. Most production comes from late synrift reservoirs, and as a result the middle and early synrift are under-explored. Also, the lack of deep well penetrations limits our understanding of the nature and distribution of hydrocarbon systems elements. In this study we show that source rock and reservoir potential can be assessed using 3D seismic geomorphic facies analysis. Geomorphic facies character and stacking suggest three stages of rift development. First, alluvial fans and red beds filled small, isolated half-grabens. As faults began to merge, subsidence increased, and deep lakes were established. Lakes slowly filled and the upper synrift is dominated by fluvial deposits. From this analysis we believe the best remaining exploration targets in the area of interest are deltaic reservoirs in the lower middle synrift.
