Kutai Basin exploration activity, East Kalimantan has been started since 19th century and continued until now. On the begining the exploration focus on the land of Kutai Basin, then with developing of exploration technology, the activity move forward to offshore then at 1995 to the deepwater. Right now is been a basic question for doing exploration in Kutai Basin, How big the prospectivity still there? Which area are the most prospect? What play system which exist? And what exploration status are Kutai Basin? And how efficient the exploration activity in Kutai Basin. The Kutai Basin hierarchy is on the growth stage till early of mature stage, meanwhile the efficiency are 44.8% with discovery prediction are 18 to 22 million barrels oil equivalen. Creaming curve show that at least 4 pattern found, which can be interpreted showing the differencies of exploration play target in Kutai Basin. On pattern that show growth stage are pattern which show the play still have enough reserves to be found. Eocene Play, Oliogocene Carbonate Play and Miocene Carbonate Play on frontier stage, Early Miocene-Middle Deltaic Play and Miocene-Pliocene Turbiditic Deepwater Play on growth stage, meanwhile Middle Miocene-Pliocene Deltaic Play on mature stage to post mature stage, but had a rejuvination become early mature stage. Approach method of exploration hierarchy versus prospectivity can be used as referable base in determining the exploration strategy in basin or in exploration play. With pursuant to the data in this time, hence exploration to more beneficial to doing is exploration in Early Miocene-Middle Deltaic Play and Miocene-Pliocene Turbiditic Deepwater Play, while Eocene, Oligocene Carbonate and Miocene Carbonate Play although give enough prospectivity but still need the larger ones effort. In Middle Miocene-Pliocene Deltaic Play the exploration activity have to focus seeking of new trap or unconventional trap and also do the seeking by pass hydrocarbon zone.
