Indonesia is one of the countries in the world that has the potential for oil and gas resources that takes a crucial role in life. Oil and gas exploitation is continuously carried out for the benefit of energy resilience in Indonesia. In the early stages, oil and gas exploitation can be carried out based on natural pressure of under the earth's surface. However, in an old oil and gas field such as the Mudi Oil and Gas Field, a water or steam injection process is required to raise the remaining oil and gas. In general, the presence of injection when the exploitation process of the old field takes place leads to deformation that threatens the safety of existing construction facilities and the surrounding environment. Based on this, it is necessary to monitor deformations that occur in oil and gas fields to mitigate disasters in the event of dangerous deformations. The goal of this research is to monitor the amount of deformation that occurs in the Mudi Oil and Gas Field using the Differential Interferometric Synthetic Aperture Radar (DInSAR) method. The used data is sentinel-1 data processed on Sentinel Application Platform (SNAP) software. The observation time range is 2017-2020. The results show different deformations occur in the Mudi Oil and Gas Field for each period (2017-2018, 2018-2019, and 2019-2020). During the three periods, there was a gradual subsidence in the well position with the lowest decline occurring in 2019-2020, which was -3,629 cm at sumur16 and sumur17 positions.
