Enhancing Porosity Prediction Accuracy in Oil Reservoirs: Evaluating Hybrid Machine Learning Approaches Integrating Well Log and Core Data

Accurate prediction of porosity holds significant importance across various domains within the oil and gas sector, encompassing activities such as reservoir delineation, well design, and production enhancement. However, conventional methodologies often encounter difficulties in capturing the intricate relationships among diverse data streams and porosity metrics. This study introduces a novel hybrid model framework aimed at refining the precision and resilience of porosity forecasts by integrating multiple machine learning methodologies and exploiting complementary data modalities. This hybrid architecture enables flexible and intricate integration of diverse models and data sources, potentially leading to enhanced overall porosity prediction accuracy. Notably, the proposed model incorporates several innovative elements, including the amalgamation of ensemble techniques and deep learning models tailored for sequential data, as well as the utilization of complementary data sources, such as well log and core data, to facilitate automatic feature learning and representation, thereby bolstering robustness and generalization capabilities. Experimental outcomes underscore the hybrid model's potential to achieve notable prediction accuracies, with R-squared values surpassing ۰.۹۳ on log data and ۰.۸۸ on core data sets, outperforming individual models. The model also exhibits commendable robustness and training efficiency, leveraging advanced methodologies such as ensemble techniques. In conclusion, this study underscores the promise of hybrid machine learning models as dependable tools for porosity prediction from core data. The insights gleaned from this research hold the potential to advance the understanding and optimization of porosity forecasting, thereby facilitating the formulation of more efficient reservoir management strategies.
