Line 90, e.g …amount of historical data… it would be better to write geological history data of stratigraphic profile …

Explain better each figure 1-4.

Explain the sentence (line 157 to 161) and the variables it contains. In which algorithms are they used?

Figure 8 should only appear after it has been presented in the text (e.g) line181 and after its discussion. Figure 9 is not referred to in the text, or explained (?).

Thank you once again for the insightful suggestions and guidance, which have undoubtedly contributed to the improvement of our manuscript.

Reviewer #1:

[1] The novelty of the work must be clearly addressed and discussed.

Response: Thank you for your feedback. The PRKD method stands out due to its unique integration of theories, computational techniques, and pattern recognition algorithms, which collectively enhance the reliability and accuracy of kick detection in drilling operations. This innovative approach effectively overcomes the limitations of traditional threshold-based methods and presents a proactive and efficient solution for kick monitoring. In our revised manuscript, we have thoroughly discussed the novelty of our research, emphasizing the distinctive aspects and contributions that our work brings to the field. We have provided a comprehensive analysis of the novelty and clearly addressed and discussed the innovative aspects of our work.

[2] The abstract still needs more quantitative results.

Response: Thank you very much for your review and valuable feedback on our paper. Here's an updated version of the abstract with additional quantitative results.

In offshore drilling, accidents such as gas invasion, overflow, and kicks are unavoidable, and they can escalate into blowouts and other catastrophic events, resulting in casualties and substantial economic losses. Therefore, ensuring drilling safety requires precise monitoring of gas invasion and overflow. Most currently utilized overflow monitoring methods at drilling sites are threshold-based. However, monitoring parameters acquired during actual drilling operations often contain noise signals, making it difficult for threshold-based methods to strike a balance between improving accuracy and minimizing false positives. In this paper, we propose a novel method called Pattern Recognition-based Kick Detection (PRKD) for diagnosing overflow in offshore drilling. This method utilizes the overflow evolution process by integrating multiphase flow calculations, data filtering theory, pattern recognition theory, the Bayesian framework, and other theoretical models. The PRKD effectively detects and monitors gas intrusion and overflow based on single parameters by analyzing the shape and wave characteristics of the curves. Through case analysis, we demonstrate that the proposed method for monitoring drilling overflow achieves high precision while maintaining a low false positive rate. By combining advanced computational techniques with pattern recognition algorithms, the PRKD improves the accuracy and reliability of kick detection, enabling proactive responses to potential risks, protecting the environment and human lives, and optimizing drilling operations. According to the case analysis, integrating the probabilistic information of pre-drilling kick and various characteristic parameters, the PRKD model with a noise amplitude of less than 8L/s exhibits superior detection performance in this instance. When the noise amplitude is 16L/s, the PRKD model detects the continuous overflow approximately 200 seconds after the real overflow, and predicts a 96.4% probability of overflow occurrence at the specified location, meeting the on-site requirements. These results highlight the effectiveness of the PRKD method in accurately detecting and predicting overflow events. The gas invasion monitoring method proposed in this paper provides accurate diagnostic results and a low false positive rate, offering valuable guidance for gas invasion monitoring in drilling operations. The quantitative results obtained through the case analysis further validate the effectiveness and reliability of the PRKD method in detecting and monitoring drilling overflow scenarios.

[3] The main objective of the work must be written on the more clear and more concise way at the end of introduction section

Response: Thank you for your feedback regarding the quality of the introduction section. We will take your comments into consideration and make the necessary improvements to enhance the quality of the introduction. In this study, our main objective is to propose a novel and reliable kick monitoring method, called Pattern Recognition-based Kick Detection (PRKD), specifically designed for offshore drilling. The PRKD method integrates the theory of multiphase flow calculation, data filtering theory, pattern recognition theory, and Bayesian framework to enhance the reliability and accuracy of kick detection. By combining advanced computational techniques with pattern recognition algorithms, PRKD enables proactive measures to mitigate potential risks, protect the environment, and optimize drilling operations. The significance and innovation of this research lie in its ability to address the limitations of existing kick monitoring methods by providing a more robust and precise approach. This novel method, PRKD, clearly outlines its research significance and innovation, making it a valuable contribution to the field of offshore drilling safety.

[4] Most tables and figures are still needed improve the quality of all tables and figures.

Response: Thank you for your feedback regarding the tables and figures in our manuscript. We have taken your comment into consideration and made the necessary revisions in our revised manuscript to enhance the quality of all tables and figures.

[5] I would also expect to validate with two more experimental works available in the literature.

Response: Thank you for pointing out the need for validation with additional experimental works available in the literature. We appreciate your suggestion, and we have taken it into consideration in our revised manuscript. However, due to the constraints of this study, it was not feasible to include validation with the specific experimental works mentioned. Nevertheless, we acknowledge the importance of validation and recognize that it is an essential aspect of research. In future studies, we intend to conduct more in-depth investigations that involve validating the data presented in the literature. By incorporating such validation in future research, we can further strengthen the reliability and robustness of our findings. We value your feedback and appreciate your input in guiding the direction of our research.

[6] Improve work justification. Also, add more analysis about velocity and pressure contours.

Response: Thank you for your feedback. We will further enhance the justification of our work and provide more analysis regarding velocity and pressure contours. Firstly, we will reinforce the rationale and significance of our study. By proposing a novel Pattern Recognition-based Kick Detection (PRKD) method, we aim to address the challenges associated with kick event monitoring in offshore drilling operations. Kick events can lead to severe accidents and losses, highlighting the criticality of accurate monitoring and prediction. Our research fills the existing gaps and offers a more reliable and precise approach to enhance kick event detection and prediction. Furthermore, we will delve into a more comprehensive analysis of parameters such as velocity and pressure distributions. By conducting a detailed investigation and analysis of these parameters, we can gain deeper insights into the evolution and relevant physical characteristics of kick events. This will aid in better understanding the mechanisms behind kick events and provide more accurate foundations for subsequent prediction and control measures. We will perform quantitative analysis on the contours of velocity and pressure parameters, offering more comprehensive and detailed research outcomes. We will strengthen the justification of our work and provide more in-depth analysis of velocity and pressure distributions to offer a more comprehensive study and results. Thank you for your suggestion, and we are committed to further improving our research.
