Identification and characterization of reservoir high permeability streak and its application

Abstract A method for quantitative characterization of high permeability streak is proposed, based on the statistics of permeability versus depth of core samples. This method solves the problem that macroscopic identification of high-permeability zones cannot be quantitatively characterized and improves the matching accuracy of reservoir simulation. In the reservoir simulation of water flooding in the S oilfield, the method was used to adjust three high permeability streaks in the model. The matching accuracy was significantly improved in the comparison before and after the adjustment. This method of identifying and characterizing high permeability streaks provides a new idea for future reservoir simulation of similar oilfields.
