Reserve Estimation Using Wireline data_OIIP_GIIP

Reserve estimation using wireline logs involves the following steps: Collect Wireline Log Data: Use logs like gamma ray, resistivity, neutron, and density to characterize the formation. Identify Hydrocarbon Zones: Use gamma ray and resistivity logs to distinguish hydrocarbon-bearing from water-bearing zones. Calculate Porosity: Estimate the amount of pore space using neutron and density logs. Determine Water Saturation (Sw): Use the Archie equation or similar models to find the fraction of pore volume filled with water. Calculate Net Pay Thickness: Identify zones with sufficient porosity and hydrocarbon saturation. Estimate Hydrocarbon Pore Volume (HCPV): Calculate the volume of hydrocarbons in place. Convert HCPV to Reserves (STOIIP): Convert hydrocarbon pore volume to stock tank barrels. Apply Recovery Factor: Determine the percentage of STOIIP that can be recovered.
