T The research area being located on JM-NITA of field, which is the administation in Salawati, West Papua Province. In this case, the inditify type and hydrocarbon prospect zone base on analysis of mineral solver, which refers to system neural network analysis. In analyzing of research area in the Kais Formation is divided into three zones of equality shapes log. In this research petrophysical analisys will be focused to porosity in the respective zone, the petrophysical parameter likes water saturation and permeability also made calculation but not for detail. The data used of the analysis is seismic 2D, wireline log and core analysis. In interpretation configuration from seismic shows their formation build-up which the research area is carbonate rock. The result of processing seismic data will be able to produce time or depth sturucture map, the facies map, the RMS amplitude map and isoporosity map. The Fasies map based on the interprestation from sismic configuration and approaced to regional. Map of fasies divided into two facies is lagoonal and patch reef. The obtained map from seismic interpretation is divided three maps based on zone from wireline log corelation. The isoporosity map most well located in the third zone, where the porosity developed in the zone is very good wells especially on JM-NITA2, JMNITA3 and JM-NITA8. The isoporosity map most well located in the second zone, where the porosity developed in the zone is good wells especially on JM-NITA1, JMNITA2, JM-NITA3 and JM-NITA8. And the isoporosity map most well located in the first zone, where the porosity develofed in the zone is fair wells especially on JMNITA1, JM-NITA3 and JM-NITA7.
