Abstract

In an exploratory drilling, it is a very important step to analyze the saturation of the fluid in the reservoir. The fluid system present in a reservoir is usually multi-phase (water and hydrocarbon). The hydrocarbon saturation (oil or gas) can be determined by calculating the water saturation, thereby determining the value water saturation (Sw = water saturation) being the key to know a reservoir interval whether the dominant contains water or hydrocarbons. The development of exploration technology, especially logging technology and various reservoir conditions affect the concept of water saturation determination over time. This study attempted to compile the types of water saturation determination methods in 7 wells data "ARA". Determine the petrophysical property as a step to characterize the well data is determine shale volume using the gamma ray index method, determine water resistivity using pickett plot method, determine porosity using density and neutron log correlation, and to determine water saturation using archie and simandoux methods. Based on analysis 7 wells data "ARA" has a fluid of gas, oil and water. The average porosity value of "ARA" is 16.2% and the average water saturation is 21.8%.
