Kraken is a reservoir data management tool, which combines powerful features of a reservoir simulation post-processor with a modern user interface able to import and handle field history data, wells trajectory and deviation files. Kraken natively reads and interprets data from Schlumberger’s ECLIPSE 100/300, CMG’s IMEX, STARS and GEM, UTCHEM and several other simulators, properly conciliating solutions, times and units, thereby providing unique ways for comparing and analyzing simulations and historical data.
