The Department of Exploration, JAPEX has developed the four systems named the BSS Utilities & Data Base, the BSS & the MINIBSS (Basin Study System), the MESS and the SUPERLOG. This paper presents an outline of the each systems.
1. Data-Base : Well-Data File, Utilities, Geochemical Log etc.
2. BSS & MINIBSS : Basin analysis or assesment, especially maturation, generation and expulsion of hydrocarbon, to reconstruct geohistory diagram.
3. MESS : the model to evaluate exploration strategies.
4. SUPERLOG : the digital processing package for a large quality of log data.
