Considering CO2 capture and storage, this study presents a workflow for assessing CCUS project viability. Focusing on southern Louisiana, we identified low-cost emitters through cost calculations and paired them with nearby storage sites. A geological model of tertiary sands was developed to determine reservoir storage volumes, injectivity, storage costs, and plume migration areas using the FE/NETL CO2 Saline Storage Cost Model. We generated a risk map considering factors such as wellbore penetrations, faults, earthquakes, caprock, freshwater aquifers, and salt domes to identify areas with higher chances of costly remediation or freshwater contamination.\u0000 Our findings reveal a significant cluster of emissions in southern Louisiana with a sub $50/tonne capture breakeven, accounting for over 80 million tonnes of CO2/year. Existing and potential pipelines can connect these emitters to storage sites with capacities ranging from 17.2 to 36.8 Mt CO2/section and storage beakevens between $8.50 and $14.50/tonne. Risk assessment indicates increased risk in the northern region due to the presence of freshwater aquifers and legacy wellbore penetrations. Comprehensive understanding of CO2 storage potential along the entire value chain is essential for project success, and our proposed workflow enables holistic screening of areas for new projects, helping secure pore space before competitors and facilitating deeper modeling in low-risk areas.","PeriodicalId":338111,"journal":{"name":"Day 1 Tue, August 22, 2023","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115782326","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}

A novel approach recently proposed is the microwave/electromagnetic-assisted catalytic heating technology for in-situ hydrogen generation and extraction directly from petroleum reservoirs. Here we further evaluate the potential of shale oil for H2 generation in the presence of shale rocks under microwave irradiation. A series of lab-scale experiments are conducted for shale oil conversion to hydrogen in Mancos shale rock samples without artificial catalysts. The real-time variations of measured temperature of rock samples, gas flow rate, and concentration of hydrogen and other generated gases are monitored. We find that the pure shale rocks can be heated up to over 600 C° without any promoter at an input power of 1.5 kW during microwave heating. A sudden increase of measured temperature of the Mancos shale is monitored at a temperature below 300 C° during microwave irradiation, referred to as \"temperature soaring\" (TS) phenomenon. Once TS phenomenon happens, the shale rock can be easily heated at a much lower microwave power. Furthermore, minerals in shale rocks have a significant natural catalytic effect on shale oil conversion to H2. A concentration of 1% hydrogen starts to be monitored in generated gases from shale oil at a measured temperature of 253-421 C° in the presence of Mancos rocks, much lower than the sample with 100% quartz at 523 C°. The highest H2 production rate and H2 concentration are 178 sccm and 77 mol.% from the conversion of 0.4 g shale oil, respectively. Additionally, long-range well-ordered carbon is commonly found in the shale rocks after microwave heating experiments.","PeriodicalId":338111,"journal":{"name":"Day 1 Tue, August 22, 2023","volume":"836 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114843888","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}

The present work investigates coupling of low-temperature geothermal resources with concentrating solar and/or natural gas energy sources to increase the number of locations at which power generation from low temperature geothermal resources would be technically and economically viable.\u0000 Stand-alone and hybrid geothermal power cycles are simulated using SimTech IPSEpro process modeling software. Design point strategies for a hybrid power cycle that may operate with either a single heat source or two simultaneous heat input sources are considered. Additionally, off-design power plant operation is investigated to consider the impacts of the heat source availability and ambient temperature variations. The off-design analysis utilizes a modeling tool that predicts power plant performance at each time step as a function of topping cycle heat input (from gas or solar), bottoming cycle heat input (from geothermal), and ambient temperature.\u0000 Addition of a steam topping cycle to an organic Rankine cycle geothermal power plant provides opportunities to increase the efficiency and power output relative to a stand-alone geothermal power plant. Additionally, use of the waste heat from gas turbine power generation in a geothermal bottoming cycle provides opportunities to increase the amount of power generation associated with each unit of carbon dioxide emitted. This paper will describe the hybrid plant configuration evaluated, discuss the predicted power cycle performance, and compare with stand-alone natural gas and geothermal power generation cases. The power cycle investigated is expected to be applicable for use with conventional hydrothermal resources as well as with geologic thermal energy storage applications and/or enhanced geothermal systems.\u0000 The steam topping cycle could use a concentrated solar heat source for fully renewable hybrid plant configuration. A plant initially constructed with a natural gas topping cycle heat source could be converted to a solar heat source part way though the power cycle operational life to achieve life cycle carbon emission reductions.","PeriodicalId":338111,"journal":{"name":"Day 1 Tue, August 22, 2023","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121743811","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}

In 2017 the SPE published the CO2 Storage Resource Management System (SRMS), as a framework for stakeholder communication. In 2022 it published the first SRMS Application Guidelines. However, working examples where the SRMS is used to communicate project status in the public domain are limited.\u0000 In 2023 the authors of this paper referred to the SRMS as the standard to complete a Competent Person's Report – a term used in the United Kingdom (UK) for an independent expert report designed to be shared with stakeholders to communicate the risk, uncertainty and commerciality of projects. This was believed to be the first application of the SRMS as a reporting tool to European equity markets.\u0000 While applying the SRMS, challenges were identified when using it as a tool for stakeholder communication.\u0000 This paper describes innovations developed to relate the SPE SRMS in a UK Competent Person's Report. First, a flowchart was developed to explain a key interpretation of the SRMS. Next a defined framework of technical milestones was developed to assess the maturity of a given technical topic within the SMRS. This was combined with radial data visualization. The combination allowed multiple storage sites to be compared simultaneously, and allowed a stakeholder to quickly identify what the maturity of technical analysis is for any given site.\u0000 We conclude that in the rapidly expanding space of CCS stakeholder engagement, the SRMS can play an important role. However, each user of the SRMS may interpret it differently and future implementation gaps will likely be identified. It is recommended that new methods of communicating SRMS challenges to the SPE be adopted, for rapid responses from the SPE to users and more consistent application of the SRMS across the globe.","PeriodicalId":338111,"journal":{"name":"Day 1 Tue, August 22, 2023","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128646879","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}

Over time, this work developed capacity assessments and conducted pilot tests to demonstrate storage efficacy. Results of these assessments suggested that large volumes of CO2 can be stored in many global basins. In parallel with this research, regulatory authorities developed frameworks to govern the injection and storage processes to assure permanency and to minimize environmental impacts.\u0000 However, these R&D and regulatory developments, by themselves, were not enough to kick-start an industry. A \"third leg\" of the stool was required, which is a viable commercial model. In a limited number of sites around the world, commercial storage projects were developed to mitigate carbon emission taxes. However, momentum has not been maintained and the portfolio of large projects has not grown. In the United States, however, the advent of tax incentives has spurred intensive commercial interest in carbon storage. This confluence of incentivization, decades long research, and an established regulatory framework has led to significant growth in carbon storage activity in projects great and small.","PeriodicalId":338111,"journal":{"name":"Day 1 Tue, August 22, 2023","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123407280","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}

Taleghani","doi":"10.2118/215751-ms","DOIUrl":"https://doi.org/10.2118/215751-ms","url":null,"abstract":"\u0000 This work provides insights into the technical and economic viability of repurposing oil and gas wells for geothermal energy production for direct heating. The potential benefits, especially for areas that are highly dependent on fossil fuels for heating, and challenges of this approach are assessed while technical, market, and policy barriers for future developments are identified. Repurposing oil and gas wells to geothermal energy requires a multidisciplinary approach that involves expertise in geology, engineering, and regulatory affairs. A thorough analysis of data on the physical, technical, economic, and environmental aspects of repurposing oil and gas wells for geothermal energy is conducted, including well logs, geologic maps, temperature and flow rate measurements, cost estimates, and environmental impact assessments. In addition, a numerical simulation is run to evaluate efficiency and power output from open-loop and closed-loop geothermal systems. The data analysis combined with numerical simulation will help determine the feasibility and potential benefits of this approach. Compared to geothermal reservoirs, the low temperature of oil and gas reservoirs often limits their potential for power generation development. However, the results demonstrate that with careful consideration of site selection, engineering, and environmental factors, repurposing oil and gas wells for geothermal community heating can be a cost-effective way to utilize existing infrastructure for renewable energy development. Even considering workover costs to ensure wellbore integrity, the approach is less costly than drilling and completing new wells. Other measures to improve efficiency include the use of high thermal conductivity materials and proper reservoir management to ensure heat is being extracted sustainably. While open-loop geothermal system resulted in higher temperatures, closed-loop avoids uncertainties in the rock properties and can be easily implemented. Factors such as the depth and location of the well, the geology of the surrounding area, and the available technology and infrastructure all play a role in determining the actual heat output from a repurposed geothermal well from oil and gas. Repurposing oil and gas wells to geothermal energy for community heating represents an innovative and sustainable approach to energy generation that makes use of existing resources and infrastructure in a new and beneficial way.","PeriodicalId":338111,"journal":{"name":"Day 1 Tue, August 22, 2023","volume":"56 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-08-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123022341","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}
