Kusuma Field is one of oil and gas field which is owned by Total E&P Indonesia and occurred in Mahakam Delta, Kutai Basin, East Kalimantan. Those are 24 wells have been investigated within an area of 18,9 km2. Interval of area research has proven as a producible natural gas and oil interval. Core, XRD, and petrography data analysis on FS 6 – FS 7 showed that major minerals existed and consisted on rock are quartz and clay minerals. Those minerals became major parameters in petrophysics study. Petrophysics study was done through multimin model by using dual water methods that refers to major parameter thus we could get deliver reliable <br /> <br /> <br /> <br /> <br /> <br /> petrophysical properties comparing with the origin. <br /> <br /> <br /> <br /> <br /> <br /> Volume of wet clay, porosity, and water saturation are those petrophysical properties which obtained from multimin analysis model. Comparation of petrophysical analysis result by lab to multimin analysis indicated coherent value. Average porosity of those potential <br /> <br /> <br /> <br /> <br /> <br /> reservoir ranging from 0,15 % - 0,2% with netsand thickness about 1 - 20 meter. Sequence sratigraphy analysis indicates this area divided into 3 types of system tract, which is Lowstand System Tract, Transgressive System Tract, and Highstand System Tract. <br /> <br /> <br /> <br /> <br /> <br /> Electrofacies log pattern which compiled with core analysis representing its grain size and depositional environment. Based on distribution of electrofacies log compiled with architectural facies model, those are divided into 4 types of architectural facies which is <br /> <br /> <br /> <br /> <br /> <br /> distributary channel, interdistributary-plain, crevasse splay, and mouth bar. Oil and gas reserves on this field is 256965 m3 dan 0.16 bcf.
