Wireline logs are used to find out the different reservoir parameters such as formation water resistivity, effective porosity, water saturation, hydrocarbon saturation, fluid type etc. Different equations, methods, plots and charts were used to find out the reservoir parameters. Shaly-sand analysis was done for clastic reservoir. For carbonate resrvoir lithology, pore types and clay minerals were throughly studied. Gamma ray, Resistivity, SP, Caliper, Density, Neutron and Sonic logs were used for the formation evaluation. MDT data was taken to determine the type of fluid. FMI logs were used for lithology and fracture determination.
