For the past three decades, global warming has been an issue we face for an excessive use of fossil fuel. Transportation and industrial exiles such as CO2 has caused greenhouse effect and damaging the quality of air and ozone. One of the technology developed is Carbon Capture Storage (CCS). Since 2012, Indonesia has been working on CCS technology. One of the testing field in Indonesia is Gundih Field, Blora District. This research aims to find the prospect area as CCS field. One of the geophysics method used to study the subsurface structure is gravity method. Application of Time Domain Electromagnetic (TDEM) method for CO2 injection. CO2 that released to the air can be reduced by using cleaner new and renewable energy (including geothermal) and applicating CCS technology. Meanwhile, since more than a decade ago, CCS technique has been evolving rapidly. A pilot study CO2 sequestration in Gundih Field is meant to test this technology in Indonesia. CO2 for injection is available; what we need is to find a place for its storage beneath the surface. Geological and geophysical data of the subsurface in Gundih Field is enough with decent quality. Therefore, a further geophysical observation to determine CO2 storage is necessary. TDEM method us one of the method that can be used in time-lapsed. An increasing value of resistivity is shown while CO2 is injected to saline formation. Saline fluids are replaced by CO2.
