Geomagnetic 3D modelling can be done by varying inclination angel for each layer and Talwani method to build the initial model as forward modelling formulation. In modelling process, random noise distribution is always needed to build synthetic data from observation data. There are two kind of random noise distribution used in this research. They are uniform distribution and Gaussian distribution. This concept then applied in satellite data of magnetic intensity in Sintang, West Borneo. Sintang is chosen because it is rich of mineralization and off course has big potential of susceptibility. Based on modelling inversion result, uniform distribution is better in separate big and low anomaly of susceptibility contrast than Gaussian distribution in this research-s data
