Geophysical Pore Type Characterization from Seismic Data in Carbonate Reservoir

Pore geometry in carbonates control the fluid flow properties and geological story, the purpose of our work is to predict pore type distribution from well observations and seismic data based on geologic understanding of the reservoir. Based on developed rock physics model which can take into account volume fraction of pore type quantitatively, we bridge the three defined geophysical pore type with extracted seismic properties from seismic data. The approach is evaluated on real well log data and seismic data from offshore Brazil carbonate reservoir, we obtain the distribution of reference pores, stiff pores and cracks which can be used to predict reservoir permeability.
