Use advice for data set When using the data from this industrial process, researchers and engineers should ensure that the gas logging derivative parameters and conventional logging response equations are appropriately selected for sensitivity to the critical fluids of interest. Accurate initial assumptions for the formation components are necessary for reliable inversion results. The calculated gas-oil ratio must be based on equations that properly account for variations in pressure, temperature, and composition of hydrocarbons under both formation and surface conditions. This methodology is advised to be incorporated into decision-making workflows for exploration and development, as it has been validated to have an accuracy rate of 94%. Consideration should also be given to the expedited application of this method to practical production to improve interpretation coincidence rate and efficiency. Users should address potential overfitting of the overdetermined equation system and computational efficiency in the optimization process.

General comment In this paper, four gas logging derivative parameters which are sensitive to critical fluids such as condensate gas and volatile oil are selected, and the optimal logging interpretation objective function is constructed together with conventional logging response equation. The formation components are inversed together, and then the key parameters of gas-oil ratio are calculated by gas state equation, so as to achieve the purpose of quantitatively identifying fluid properties by comprehensive logging data

Technical purpose The technical usage of the described industrial process is to facilitate the identification of fluid properties in petroleum exploration within the Zhusan Depression in the Pearl River Mouth Basin. By employing a combination of gas logging derivative parameters, conventional logging response equations, and gas state equations, this process enables the accurate calculation of the gas-oil ratio, which is a critical indicator for classifying hydrocarbon resources like condensate gas and volatile oil. It is primarily used in the interpretation of formation components to improve the accuracy of exploration and development decisions in the oil and gas industry.
