Determination of the potential source rock in Block A, West Natuna Basin is still problematic and has a high uncertainty. Several studies have shown that coal shale <br /> <br /> from Arang Formation is a rich source rock, but the depth is to low and predicted not a good source rock. As well the Upper Gabus Formation, despite having a good maturity, but based on the analysis of the source rock geochemistry and correlation have not shown positive results. <br /> <br /> The research was conducted to enrich the existing maturity models in Block A and made to minimize sources of uncertainty that exist in the source rock in these <br /> <br /> blocks. Modeling maturity of the source rock at block A is done by modeling the burial history and backstripping to get the source rock maturity model and then compared with the geochemical parameters for each source rock. To be a potential source rock, besides having a maturity also need the other requirement such as richness and suitable organic materials. <br /> <br /> Based on maturity modeling shows every well have been different result. In general, the maturity gained from the Barat Formation, Upper Gabus Formation, Keras Formation, Lower Gabus Formation and Benua/Lama Formation. However, <br /> <br /> based on geochemistry parameters and lithology, only the source rock of the Barat Formation, Keras Formation and Benua/Lama Formation considered to be a potential source rock for this area.
