D Daerah penelitian berada pada lapangan “NAP”, yaitu secara administratif terletakpada Blok Tuban, Provinsi Jawa Timur. Dalam penelitian ini dilakukan beberapaanalisa menggunakan data log yang dipadukan dengan data batuan inti, yaituanalisa litofasies, analisa sekuen stratigrafi, lingkungan pengendapan, parameterpetrofisika, dan unit rock type yang berada pada zona batuan karbonat FormasiTuban dari sumur NG-1, NG-2, NG-3, NG-4 dan NG-5. Berdasarkan data litofasiesdaerah penelitian yang ada pada sumur NG-1, lapisan “N” pada lapangan "NAP"dibagi menjadi lingkungan pengendapan fore reef dan inter reef. Berdasarkan hasilperhitungan dan penentuan unit R35 (metode Winland), rock type pada lapangan“NAP” terbagi menjadi macroport, mesoport, dan microport. Rock type macroportmerupakan rock type yang mendominasi lapisan “N”. Lapisan N dengan potensireservoir terbaik ada pada sumur NG-4 dengan nilai rata – rata porositas sebesar0.179 dan nilai rata – rata permeabilitas 85 md. Sumur pengembangan berdasarkannilai rata – rata porositas dan permeabilitas lapisan “N” ada berada pada daerahbarat daya dan di tengah lapangan NAP.

T The research area are located on the field ”NAP”, which is administratively inTuban Block, East Java Province. In this research was conducted a several analysisbased on log data that validated with core data. The analysis are lithofacies analysis,sequence stratigraphy analysis, depositional environment analysis, petrophysicsanalysis, and rock typing interpretation which are located at carbonate rocks zoneof Tuban Formation from well NG-1, NG-2, NG-3, NG-4 and NG-5. Based on thelithofacies data from the core of well NG-1 there are two depositional environmentin the “N” layer of field “NAP” that is fore reef and inter reef. Based on thecalculation of the petrophysics parameters and the R35 (Windland Method) unit,there are three rock types in “NAP” field that is macroport, mesoport, and microportrock types. The macroport rock type is the dominant rock type of “N” layer. Thearea of which has the greatest potential of a reservoir is located in well NG-4 withan average value of porosity of 0.179 and an average value of permeability of 85md. The development wells that are based on the values of both porosity andpermeability are advised on the southwest and middle area of “NAP” field.
