<p align="justify">In the previous exploration of Kenanga Field, Cisubuh Formation was not a target. It because there is shallow gas in Cisubuh Formation which can caused technical problem when drilling execution. But as increased of gas demand, exploration is aggressively encouraged in new or existing zones such as shallow gas in Cisubuh Formation. KK-15 is sandstone reservoir located at Cisubuh Formation with depth approximately 400-500 m TVDSS. SAP-1 Well which located nearby Kenanga Field was done drill stem test (DST) in KK-15 interval and gets gas with initial rate 7 MMSCFD. An integration analysis between log and seismic data are important in this research. Gas zone is indicated by high gas reading in mud log. In wireline log, it is indicated by high resistivity reading and crossed over between RHOB and NPHI. In seismic, shallow gas is recognized as bright amplitude which called bright spot. By extracting seismic amplitude, it is very useful in delineating the reservoir geometry since the gas zone is indicated by bright amplitude in seismic. By AVO interpretation, it can be an assurance in defining the gas zone. KK-15 is interpreted as shallow gas zone which deposited in tidal flats as tidal sand ridge. This reservoir has wide dimension 12 x 5 km. Volumetric calculation has been done by deterministic method. Based on the calculation, it can be known that the KK-15 reservoir has gas in place 64.6 BCF.<p align="justify">
