Abstract
This research study focuses on the use of tools for well X05-NC169a in the X field in Libya. Tools such as the reservoir saturation tool and the repeat formation tool are used in this study. F3-Sand Stone is the main reservoir and has a gross thickness ranging from 130 to 187 feet. The aim of this study is to identify the type of fluid and to determine fluid contacts in the F3 - Sand Stone Reservoir. The study was based on a petro-physical evaluation of the well X05-NC169a by using log data (Gamma Ray Log, Resistivity Log, Neutron Log, and Density Log). The Techlog software was used to analyze the log data, while the Surfer software was used for mapping. The results indicate that it has a hydrocarbon and water column. Apart from combining the petro-physical results of well tests (RFT data and RST), it is to define the reservoir fluid type. The fluid contacts changed when the hydrocarbon fluid level decreased. The most dominant hydrocarbon in the reservoir, according to RFT, RST, and petrophysics data, is predominantly two phases. Zones of gas and oil.
