In this study, natural rock cores taken from deep reservoirs in the Ordos Basin and Fukang, Xinjiang are used as research objects. Nine groups of core-flooding experiments are performed under different CO<sub>2</sub>/N<sub>2</sub> gas mixture ratios to study the influence of rock properties (mineral composition, permeability, porosity and pore structure) on the residual water. Furthermore, the geophysical and chemical properties of rock cores are analyzed by X-ray diffraction, electron microscopy, field emission scanning electron microscopy and piezoelectric mercury method. The results show that residual water saturation is a quantitative power function of drainage time. The residual water saturation is positively correlated with the total amount of quartz and feldspar and increases with increasing permeability. Moreover, both the average and median pore throat radius show a strong inverse correlation with irreducible residual water saturation; as these radius increase, the residual water saturation decreases. In contrast, the porosity and maximum pore throat radius display a weaker correlation with irreducible residual water saturation.

However, there is still a need for early plume evaluations to risk and rank injection sites relative to each other. Therefore, an alternative fluid migration method called invasion percolation is adopted for the CCS screening phase to predict the extent and location of CO<sub>2</sub> plumes in the subsurface. Invasion percolation as part of basin modeling is a rapid method, which requires limited data and is ideal for the early screening phase. Invasion percolation results are compared to uncalibrated reservoir models, typical for the screening phase, revealing that plume location shape and size are very reasonable especially when compared to seismic observed plume outlines. It can be concluded that invasion percolation as part of basin modeling is a fit for purpose method, which can assess multiple opportunities rapidly during the early intake screening phase to risk and rank opportunities relative to each other and to build a CCS injection site portfolio. In addition to the plume evaluation, basin models can provide useful basin-scale or injection site specific pressure and temperature predictions as well as CO<sub>2</sub> density estimates for static volume calculations before detailed reservoir and stratigraphic models are available. © 2024 Society of Chemical Industry and John Wiley &amp; Sons, Ltd.</p>","PeriodicalId":12796,"journal":{"name":"Greenhouse Gases: Science and Technology","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142429307","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For offshore operations, ship transportation is considered a viable alternative, and this would entail operations at low temperatures (down to 223.15 K). A review of the literature revealed that there is limited experimental data on CO<sub>2</sub>-rich systems at low temperatures, thus, the need to investigate the phase behaviour of CO<sub>2</sub>-rich systems at these conditions. This study validated and compared the accuracies of Peng–Robinson (PR) equation of state (EoS) with three different mixing rules (the classical with original and adjusted binary interaction parameters, the Wong–Sandler, and the Orbey–Wong–Sandler mixing rules) against the multi-fluid helmholtz energy approximation (MFHEA - with original and adjusted binary-specific reducing parameters) EoS in the prediction of bubble points of CO<sub>2</sub>-rich binary systems (CO<sub>2</sub>-CH<sub>4</sub>, CO<sub>2</sub>–O<sub>2</sub>, CO<sub>2</sub>–Ar, and CO<sub>2</sub>–N<sub>2</sub>) for CCUS applications. The experimental studies used for the validation of the models were conducted at low temperatures (228.15–273.15 K with overall uncertainties of 0.14 K) and for five different CO<sub>2</sub> mole ratios (99.5, 99, 98.5, 98 and 95% with overall uncertainties of 0.032%) using the constant composition expansion method. The overall uncertainty of the pressure measurements was 0.03 MPa. From the study, it was observed that there was a significant effect of binary interaction parameters (BIP) adjustment on the performance of PR-EoS with classical mixing rule, especially for the CO<sub>2</sub>–N<sub>2</sub> system. For all the systems, the predictions of PR-EoS with the classical mixing rules and the adjusted BIPs were the most accurate in terms of the average absolute deviations from the experimental data. The model also predicted the literature data well in comparison with the other models (with less than 5% deviations for all the data points). Further analysis also proved that the model dew point predictions were in reasonable agreement with the available literature data at the considered conditions. As a result, the model could be adopted to fill the existing knowledge gaps of the studied systems at conditions (143.15–223.15 K) where experimental studies were not feasible. © 2024 The Author(s). <i>Greenhouse Gases: Science and Technology</i> published by Society of Chemical Industry and John Wiley &amp; Sons Ltd.</p>","PeriodicalId":12796,"journal":{"name":"Greenhouse Gases: Science and Technology","volume":null,"pages":null},"PeriodicalIF":2.7,"publicationDate":"2024-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ghg.2300","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142430069","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
