Resolution preserving methodology to generate continuous log scale reservoir permeability profile from petrographic thin section images

A method of generating advanced log scale permeability estimations for a well, comprising the following steps:

• deploying an log scale permeability estimation system, comprising:
• a high-resolution microscope configured to take photographs of a plurality of petrographic thin section samples and create petrographic thin section sample digital image files from the photographs, and
• a computer system configured with specialized software to perform a first specialized function and a second specialized function:
• the first specialized function to receive the petrographic thin section sample digital image files from the high-resolution microscope and analyze the petrographic thin section sample digital image files to determine a permeability estimation for each of the petrographic thin section sample digital image files and further configured to receive and store depth information associated with each of the plurality of petrographic thin section samples and the respective permeability estimation into a permeability estimation log;
• the second specialized function to combine the permeability estimation log with a set of corresponding wireline logs to form a calibration log, the computer system further configured to perform machine learning on a majority portion of the calibration log, generate a calibrated model, validate the calibrated model with a remaining portion of the calibration log, and determine if the calibrated model is within a pre-identified error threshold such that it can be considered a validated model;
• the computer system further comprising:
• a computer circuit board,
• a microprocessor configured on the computer circuit board, the microprocessor configured with input/output channels,
• memory configured to be in communication with the microprocessor,
• a data bus extending between the memory and the microprocessor, and
• a network interface configured to be in communication with the microprocessor,
• non-volatile memory configured to be in communication with the microprocessor, and
• a specialized software program stored on the nonvolatile memory that enables the microprocessor to perform each of the first specialized function and the second specialized function;
• the method further comprising the step of:
• performing processing steps, by the computer, system, to perform each of the first specialized function and the second specialized function.
