Abstract

Systems and methods include a method for determining perforation cluster points of a reservoir. A rock type of a geological formation of a reservoir is determined using petrophysical data. The transmissible sublayers of the reservoir are determined by grouping the petrophysical data into different subset transmissible layers based on cut-off criteria. Net transmissible reservoir footage for the transmissible sublayers are generated based on averages of parameters for minimum and maximum measured depths. Potential stages for the reservoir are determined using a conditional formatting on the transmissible reservoir footage. Potential perforation cluster points selected based on the potential stages for the reservoir are received from input of an engineer.
