Petrophysical modeling of baturaja formation in zaman field using winland r35 and flow zone indicator

Zaman Field is located approximately 150 km from Palembang City, in the South Sumatera Basin. The gas field comprises a carbonate reservoir that managed by the Pertamina EP located in Baturaja Formation. Baturaja Formation has a problem with heterogeneity and became necessary to perform the task of...
