Such cyclic loads can potentially lead to wellbore failure due to fatigue, i.e. the gradual reduction of rock strength due to repeated loading at stresses below failure strength. While instances of wellbore failure due to vibration-induced loads from the drill string have been reported, research in this area remains limited. This paper introduces an elasto-plastic damage model designed to assess rock failure under cyclic loading. The Drucker-Prager elasto-plastic model with nonlinear hardening served as the foundational framework for the computational analysis. Additionally, a coupled damage model was proposed to simulate material strength degradation under cyclic loading. This customized elasto-plastic model, along with the coupled damage model, was implemented as a user-defined subroutine in Abaqus. The accuracy of the model is verified using existing experimental fatigue test data from the literature, demonstrating a good agreement between the predictions of the proposed model and the experimental findings. Utilizing this validated model, the impact of drill string vibrations on wellbore stability is further investigated. The findings underscore the significance of accounting for the repetitive impacts of the drill string, as they weaken the material strength. Relying solely on assessments of wellbore stability without considering the drill string impact seems to be overly optimistic. Notably, drill string vibrations result in damage localization around the wellbore, leading to the formation of localized bands. These bands eventually intersect, culminating in wellbore failure. The introduced elasto-plastic damage model offers a robust tool for evaluating rock fatigue failure.</div></div>","PeriodicalId":100568,"journal":{"name":"Gas Science and Engineering","volume":"138 ","pages":"Article 205607"},"PeriodicalIF":0.0,"publicationDate":"2025-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143629296","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although there are potentially several techniques for tackling CO<sub>2</sub> separation from gas mixtures, membrane technology is one of the most promising techniques because of its ease of use, affordability, and energy efficiency. However, the characteristics of the membrane material have a significant impact on how well CO<sub>2</sub> membrane separation works. Recently, metal organic frameworks (MOFs) have emerged as attractive materials for fabricating membranes with high CO<sub>2</sub> permeability and selectivity. However, comprehensive and up-to-date reviews on this topic are still limited in the published literature, highlighting that this review is timely and of great need. In this article, the manufacturing processes, difficulties, and developments of MOF-based mixed matrix membranes (MMMs) for CO<sub>2</sub> separation are thoroughly covered in this paper. Recent research shows that by including MOFs into polymeric matrix, the drawbacks of traditional membranes can be overcome and thermal stability, chemical resistance, and separation performance greatly improved. Critical evaluation is given to the impact of process variables as well as the thermal and chemical stability of MOFs-based membranes. This article also evaluates the energy consumption and the environmental impact of CO<sub>2</sub> separation using MOFs-based membranes. Issues such as economic aspects of MOFs synthesis and membrane fabrication, scalability, and long-term durability are highlighted and future research to address them has been suggested to push this technology a step closer towards practical applications. This study also highlights the enormous potential of MMMs fabricated using MOFs as an environmentally friendly way to effectively separate CO<sub>2</sub>.</div></div>","PeriodicalId":100568,"journal":{"name":"Gas Science and Engineering","volume":"138 ","pages":"Article 205604"},"PeriodicalIF":0.0,"publicationDate":"2025-03-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143684608","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, under high-pressure conditions, hydrogen may induce hydrogen embrittlement, threatening the structural integrity of pipelines. In this study, using the Materials Studio software and molecular dynamics simulations, a multilayer adsorption model for hydrogen molecules on the iron (110) surface was established, and the effects of adsorption energy, temperature, and pressure on the hydrogen adsorption process were analyzed. The results show that the adsorption energy of hydrogen molecules on the iron surface increases with pressure, leading to significantly improved adsorption stability. In contrast, as the temperature increases, the adsorption energy also rises, but the adsorption stability decreases, with some hydrogen molecules desorbing from the surface. Through radial distribution function (RDF) and hydrogen molecule trajectory analysis, this study proposed a model for calculating hydrogen adsorption amounts, which was experimentally validated for accuracy.

Residual trapping renders CO<sub>2</sub> immobile in form of clusters under equilibrium conditions within the pore spaces. Pore network modeling and machine learning techniques have been applied to further investigate the influence of porous media structural properties on residual gas trapping. Multiphase flow behavior in CO<sub>2</sub> – brine systems was investigated on 28 porous media samples representing sandstone, carbonates and sandpacks. The porous media information was extracted from Micro CT images of these samples to create pore networks and obtain structural properties. The porous media structural properties and simulation results were used as input data for machine learning models. SVM and XGBoost were deployed to predict residual saturation and classify the rock structures on their trapping potential. Pore size and throat size distribution, pore – throat ratio and connectivity impacted the fluid transport behavior within the porous media. High capillary pressure was observed in samples with small pores and throats distributed non-uniformly in the media such as sandstone and carbonates. Higher residual trapping was observed in larger pore-throat ratios which is conducive for snapoff events. The more the connectivity in the porous media, less trapping was observed as connectivity affects the ability of fluid to escape the media from one end to the other. The prediction of residual carbon dioxide was successful for both machine learning models with XGBoost model performing better than SVR in regression with a correlation coefficient of 0.97. Residual CO<sub>2</sub> saturation was classified into high (&gt;0.5) and low (&lt;0.5) to create a binary classification on which XGBoost performed better than SVC with a 100 % accuracy.

Injecting CO<sub>2</sub> into such formations; however, does not ensure safe storage because CO<sub>2</sub> could leak to the surface or pollute the formation water. The current study presents the methodology used to study structural, residual, and solubility trapping to propose an operational strategy for efficient CO<sub>2</sub> storage in the sandstone saline aquifers in the Paraná basin, Brazil. Three models were developed from various sections of the Rio Bonito Formation, each characterized by different depths and distinct reservoir properties. In the optimization process, geological uncertainties were addressed by using representative samples obtained from a set of unconditional realizations. In addition, robust optimization aimed to find an optimal solution across uncertainties for WAG and brine production. Preliminary findings suggest that brine production enhances reservoir injectivity, while WAG injection alters trapping mechanisms, increasing dissolved and residual trapping by around 15%. Moreover, WAG injection decreases the vertical migration of the CO<sub>2</sub> plume and reduces the reliance of the process on structural trapping. Robust optimization significantly increases cumulative CO<sub>2</sub> trapping by adjusting the water and gas injection periods and water production and injection rates. Sensitivity analysis indicates that increasing the gas injection period boosts cumulative trapping but lowers the trapping ratio, whereas increasing the water injection period has the opposite effect. Based on the cost analysis, shallow depths offer the lowest levelized cost and reinjection cost, making them the most economically viable option for CO<sub>2</sub> storage. To the authors' knowledge, this research marks a novel contribution to dynamic simulations of CCS projects, focusing specifically on the Rio Bonito Formation, Brazil.
