Kutai Basin is the widest basin (165.000 km2) and the deepest (12.000 14.000) in Indonesia located on east coast of Borneo and the exposure area next to it. The focus areas of research are Guntur Field located in KutaiKartanegara District, East Kalimantan Province. Oil and Gas reserves at GUNTUR Field are located in the Mentawir Formation, Kutai Basin.

In this research focused on modeling of petrophysics with the distribution of rock property with petrophysical analysis to calculate the value of clay volume, porosity, permeability and water saturation (sw). In the distribution of rock properties, variogram and co krigging methods are required in the modeling.

Based on the result of Guntur field map modeling, 8 thickness maps and 9 depth maps were obtained. The result of modeling of petrophysics at Guntur field, the appearance of rock property value is focused on the TS 3 SB 3 zone has a clay volume value of 0.01 - 0.5, the porosity value is about 0.3-0.4, the water saturation value (SW) is about 0.1 - 0.28 and the permeability is 5 - 400 mD.
