2D seismic resolution on the �MHS� field, is not sufficient for detailed seismic interpretation, especially in the target horizon (Sand Telisa, Baturaja, Talang Akar and Basement Formation), so it requires better data quality for the development of the field. In the �MHS� field in the transition zone, it is not possible to use conventional streamer vessels with shallow marine geological conditions so the solution is to use the Ocean Bottom Nodes (OBN) acquisition technology. Determination of parameter acquisition was carried out based on previous 2D geological seismic data models. Optimization of parameter acquisition design is done by calculation methods, such as bin size (spatial sampling), record length, far offset, minimum near offset, maximum frequency unliasing, tuning thickness, aperture migration. This study makes a comparison of geometry survey orthogonal-1, orthogonal-2, orthogonal-3, semipacth-1, semipacth-2 and semipacth-3 which will be simulated for analysis of the distribution of fold coverage, offset distribution and azimuth distribution in order to find the most economical geometry and efficiency for the field survey. From the simulated result, it is recommended to use Orthogonal-3 with a bin size of 12.5 x 12.5m, Shot Line Interval (SLI) of 200 m, Shot Point Interval (SPI) of 25 m, Salvo 6 SP, Receiver Line Interval (RLI) of 150 m, Receiver Interval (RI) of 25 m, Receiver Line active 14, Receiver per Line 124, maximum near offset of 250 m, far offset 2150 m in order to get maximum fold coverage 72, which has good offset and azimuth distribution, better in efficiency and is certainly economical compared to other geometry.
