Advancements in Production Optimization through an Innovative Hybrid Data-Physics Architecture
Bibliographic record
Abstract
Abstract This research addresses the challenges in using machine learning (ML) to assess and optimize production in unconventional wells, where computational costs (dependence on the accuracy of physical models) and complexity of wellbore design create significant challenges for decision-making and field development. A novel Hybrid Data-Physics (HDP) architecture is proposed that integrates data-driven models with physics equations embedded in a deep neural network (DNN). This approach optimizes both network and physical parameters simultaneously to predict short and long-term production rates, thereby generating more realistic operational scenarios. Using a comprehensive dataset from nearly 1300 Duvernay wells within the Western Canadian Sedimentary Basin (WCSB), the proposed HDP model significantly improves production performance estimations by refining physical parameters through iterative neural network processes. The model performs exceptionally well even with limited data, particularly in unconventional wells where geological complexities pose challenges for traditional simulation methods. By incorporating simpler equations such as decline curves, the HDP model bypasses the need for complex physics, capturing hidden complexities and operational trends. This study highlights the HDP model's transformative potential in production optimization, merging data analytics with physics-based modeling to enhance operational insights and decision-making. This pioneering approach reduces uncertainty and adapts to dynamic conditions, offering a robust, efficient tool for unconventional reservoir management. Additionally, the HDP model's ability to integrate various data types and adapt to evolving conditions underscores its versatility and practical applicability in real-world scenarios. Through this integration, the model not only enhances predictive accuracy but also provides a scalable solution that can be tailored to diverse reservoir conditions and operational needs.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
