Fault Delineation and Geological Carbon Storage (GCS) Characterization for the CCS and CCUS Facilities Based On Gravity Dataset. A Case Study in the Northern Part of East Java, Indonesia

Abstract lobal warming, the impact of greenhouse-gases emission has triggered climate change and caused various geological hydro-meteorological disasters in world. Most countries have carried out decarbonization efforts following Paris Agreement, which aims to reduce carbon emissions from 29% domestic effort up 41% with international support by 2030. Sustainable Development Goal number 13 states combating is a globally accepted framework adopted Indonesian Ministry Planning. One aspect involves establishing successful CCS/CCUS facilities, requires readiness storage (GCS). The GCS limited capacity, locate specifically underneath, must consider nearby faulting system avoid leakage uncontrollable behavior after injection phase liquefied (high-pressure) carbon. This study optimizes gravity dataset analysis identify existing faults characterize initial stage proposed northern part East Java, Indonesia. Synthetic modeling strike slip fault was conducted data interpretation. characterizations, include shape, depth, capacity estimations, are inferred through 3D inverse modeling. deduced presence large-scale anticline closure without any intersecting strike-slip area. identified as Baribis-Kendeng Reverse Fault Zone, trending west-east, intersected sinistral northeast-southwest direction. area suggested potential location low-risk leakage, located adjacent Central Processing Plant Gundih Sukowati Indonesia
