Abstract: The present invention discloses a three-dimensional in-situ characterization method for heterogeneity in generating and reserving performances of shale. The method includes the following steps: establishing a logging in-situ interpretation model of generating and reserving parameters based on lithofacies-lithofacies-well coupling, and completing single-well interpretation; establishing a 3D seismic in-situ interpretation model of generating and reserving parameters by using well-seismic coupling; establishing a spatial in-situ framework of a layer group based on lithofacies-well-seismic coupling, and establishing a spatial distribution trend framework of small layers of a shale formation by using 3D visualized comparison of a vertical well; and implementing 3D in-situ accurate characterization of shale generating and reserving performance parameters by using lithofacies-well-seismic coupling based on the establishment of the seismic-lithofacies dual-control parameter field. The present invention integrates an in-situ technology into shale logging, seismic generating and reserving parameter interpretation, and the establishment of a 3D mesh model of small layers of shale, which realizes the accurate description of the heterogeneity in TOC content and porosity value of shale oil and gas in a 3D space, and provides a reliable technical support for shale oil and gas exploration and development.

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.
