Gravity and elevation data of geothermal field �KIRANA� in 2002 and 2008 was used in this research. The data was gathered from 40 points of gravity measurement. Gravity value in 2002 was compared with gravity value in 2008 to look for the value changes. Changes in value of gravity with elevation changes correction contour map was made in order to see the distribution of anomalies in geothermal field �KIRANA� and also to do the calculation of mass changes. The result of mapping the gravity observation value is the lowest gravity value found in the northern area and be enlarged to the west of the research area. For the 4D microgravity anomaly mapping, the descent gravity value found in the western area and areas which have production wells (northern research area), whereas the increment of the value of gravity found in injection wells research area (southern part of the research area ). The result of Mass changes which are calculated based on gravity value changes is 51.027 megatons. As a result of distribution gravity value changes, injection wells were set up in the western and northern of research areas.
