However, it is inherently time-intensive and demands substantial geological expertise for accurate model evaluation. Furthermore, traditional machine learning techniques often struggle to predict mineralogy accurately and sometimes produce estimations that violate fundamental physical principles. To address this, we present a new approach using Physics-Integrated Neural Networks (PINNs), that combines data-driven learning with domain-specific physical constraints, embedding petrophysical relationships directly into the neural network architecture. This approach enforces that predictions adhere to physical laws. The methodology is applied to the Broom Creek Deep Saline aquifer, a CO<sub>2</sub> sequestration site in the Williston Basin, to predict the volumes of key mineral constituents—quartz, dolomite, feldspar, anhydrite, illite—along with porosity. Compared to traditional artificial neural networks (ANN), the PINN approach demonstrates higher accuracy and better generalizability, significantly enhancing predictive performance on unseen well datasets. The average mean error across the three blind wells is 0.123 for ANN and 0.042 for PINN, highlighting the superior accuracy of the PINN approach.

This study performed multiple experimental analyses on nine samples from the area to determine the petrological and petrophysical properties, as well as the PTS characteristics of reservoirs in different provenance-controlled regions. On this basis, the pore-throat size distribution (PSD) obtained from high-pressure mercury injection (HPMI) was utilized to convert the NMR movable fluid <em>T</em><sub>2</sub> spectrum, allowing for quantitative characterization of the full PSD and the occurrence characteristics of movable fluids. A systematic analysis was conducted on the primary controlling factors affecting fluid mobility in the reservoir. The results indicated that the lithology in the eastern and western regions is lithic arkose. The eastern sandstones, being farther from the provenance, exhibit higher contents of feldspar and lithic fragments, along with the development of more dissolution pores. The reservoir possesses good petrophysical properties, low displacement pressure, and high pore-throat connectivity and homogeneity, indicating strong fluid mobility. In contrast, the western sandstones, being nearer to the provenance, exhibit poor grain sorting, high contents of lithic fragments, strong compaction and cementation effects, resulting in poor petrophysical properties, and strong pore-throat heterogeneity, revealing weak fluid mobility. The range of full PSD in the eastern reservoir is wider than that in the western reservoir, with relatively well-developed macropores. The macropores are the primary space for occurrence of movable fluids, and controls the fluid mobility of the reservoir. The effective porosity of movable fluids (EPMF) quantitatively represents the pore space occupied by movable fluids within the reservoir and correlates well with porosity, permeability, and PTS parameters, making it a valuable parameter for evaluating fluid mobility. Under the multi-provenance system, the eastern and western reservoirs underwent different sedimentation and diagenesis processes, resulting in differential distribution of reservoir mineral components and pore types, which in turn affects the PTS heterogeneity and reservoir quality. The composition and content of reservoir minerals are intrinsic factors influencing fluid mobility, while the microscopic PTS is the primary factor controlling it. Low clay mineral content, well-developed macropores, and weak pore-throat heterogeneity all contribute to the storage and seepage of reservoir fluids.</div></div>","PeriodicalId":100469,"journal":{"name":"Energy Geoscience","volume":"6 2","pages":"Article 100407"},"PeriodicalIF":0.0,"publicationDate":"2025-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143816085","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, previous studies rely excessively on conceptual models and typically do not integrate multiple types of data to perform such task. Moreover, to date, no feasibility-like studies have assessed the reasonableness of such approaches. We propose a data-driven approach that utilises upscaled well logs (Young's modulus, Poisson's ratio, and silica content) alongside seismic attributes (curvature, distance to fault) to predict fracture intensity. The distance to fault is measured using the fault probability volume estimated by a pre-trained convolutional neural network (CNN). We evaluate the effectiveness of this data-driven approach employing two tree-ensemble models, eXtreme Gradient Boosting (XGBoost) and Random Forest, to estimate the volumetric fracture intensity (P32) in the wells. Regression and residual analyses indicate that XGBoost outperforms Random Forest. Results from feature importance methods, such as permutation importance and Shapley Additive explanations (SHAP), highlight curvature as the most important feature, followed by distance to fault, Young's modulus (or P-Impedance), silica content, and Poisson's ratio. The approach has been validated with rock sampling information and two blind tests. Consequently, we believe this workflow can be applied to other wells in nearby fields. The study offers a valuable tool for quantitatively estimating fracture intensity in pre-salt reservoirs. Future research may use this study as a reference for estimating fracture intensity within a seismic volume. The predicted fracture intensity estimates can enhance the reliability of reservoir porosity models and serve as a geohazard indicator to mitigate drilling risks.</div></div>","PeriodicalId":100469,"journal":{"name":"Energy Geoscience","volume":"6 2","pages":"Article 100404"},"PeriodicalIF":0.0,"publicationDate":"2025-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143816084","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
