Abstract: <br /> <br /> <br /> <br /> <br /> <br /> <br /> Water injection in oil field X was carried out to maintain and/or increase the oil production. Microgravity time-lapse survey was conducted to monitor the effect of the water injection for certain period. Survey was caried out at oil field X for two period, May 2005 and December 2005. The aquisition use Gravitymeter Lacoste and Romberg G1158 type with Alliod System and Scintrex CG5 Autograv. <br /> <br /> <br /> <br /> <br /> <br /> <br /> Distribution map was generated from the data after being filterized using Moving Average method with 5 x 5 window. From the time-lapse gravity anomaly concluded that survey area can be categorized to 3 compartment. The first compartmen shows zero time-lapse anomaly which indicate that there were no mass change in between the two survey period. The second compartment shows positive anomaly which indicate there were mass increasing due to the injection process. The third compartment shows negative anomaly which indicate mass decreasing due to the production process. <br />
