North Central Java Basin is an interesting area for study because of hydrocarbon accumulations in the Western and Eastern regions of the Central Java Basin. It is very important to understand these hydrocarbon systems in order to understand hydrocarbon potential in Java basins. To date, hydrocarbon exploration in those areas could not explain those petroleum systems. Problems of source rock, reservoir and trap are still matters that must be studied further, although these factors are present in the Tanjung-Brebes Area.Dead oils and hydrocarbon seepages in this area indicate that a petroleum system is already present. Though, the presence of source rocks and timing of hydrocarbon migration is still unsolved. Thick sandstone outcrops near dead oil with slumping structures generated by a gravity system appears to be analogous to Halang Formation in the subsurface. Seismic sections show large structures associated with sediment mass transport complexes (MTC), which are produced by gravity flow. Understanding provenance and distribution of MTC is important for locating potential reservoirs. Surface structures show NW-SE trend with a pattern that resembles a horse tail. Uplift of old formations is indicative of a system of strike slip. Traps associated with these structures could be very important for the accumulation of hydrocarbons.Keyword: Strike-Slip.
