The time-lapse microgravity anomaly survey was performed in the purpose of searching the subsurface targets to discover an anomaly caused by the survey target. To isolate the source of the anomaly, an existing filter was generally used. For this certain purpose, the filter must be constructed in a way it can receive less than the maximum results. One problem is the source of the unwanted anomaly still attached to the preliminary data. As it is known, the source of time-lapse microgravity anomaly caused by the subsidence and fluid dynamics is idencated by the increases and decreases in groundwater levels. Therefore, the survey should minimize one of these anomalies sources by adjusting the filter field conditions. In this study, the constructed filter is referred as the MBF (Model Based Filter), this filter was constructed with attention-dimensional parameter source of the anomaly. © 2017 Author(s).
