A Breakthrough in Reservoir Porosity Estimation Using Dominant Frequencies Extracted from 3-D Seismic Wavelets

1 A-27 A BREAKTHROUGH IN RESERVOIR POROSITY ESTIMATION USING DOMINANT FREQUENCIES EXTRACTED FROM 3-D SEISMIC WAVELETS Abstract Hydrocarbons accumulate in reservoir rock pore spaces which makes porosity estimation one of the major applications in oil and gas industries. Two methods are currently used in the industry to estimate porosity. The first is the well logs-based method that depends mainly on empirical formula used to transfer reservoir rock physical properties into porosity. The second is based on empirical equation which linearly (e.g. regression formula) relates well logs estimated porosity and seismic impedance and then populates the relation between wells. A new
