ChatGPT, a sophisticated online chatbot, sent shockwaves through many sectors once reports filtered that it could pass exams. In higher education, has raised questions about the authenticity of assessment and challenges in detecting plagiarism. Amongst resulting frenetic hubbub, hints potential opportunities how ChatGPT support learning development critical thinking have also emerged. this paper, we examine may affect engineering education by exploring responses to existing prompts from ten...
More than a year has passed since reports of ChatGPT-3.5's capability to pass exams sent shockwaves through education circles. These initial concerns led multi-institutional and multi-disciplinary study assess the performance Generative Artificial Intelligence (GenAI) against assessment tasks used across 10 engineering subjects, showcasing GenAI. Assessment types included online quiz, numerical, oral, visual, programming writing (experimentation, project, reflection critical thinking,...
Existing pilot, demonstration and commercial storage projects have demonstrated that CO2 geological is technically feasible. However, these do not operate at a scale necessary to make significant reduction in greenhouse gas emissions into the atmosphere. The infrastructure for injecting carbon dioxide will need be an order of magnitude larger than current CCS projects, comparable size existing petroleum installations. In most cases, injection scheme consist multiple wells, potentially...
Abstract This paper investigates ways in which CO2 storage low-permeability formations might be made viable and how such compete with more distant higher permeability. Hypothetical, but realistic cases are postulated to examine the effect of reservoir engineering economic sensitivities. The compare (a) a large source nearby abundant pore space (0.1–10md) (b) same remote high permeability (100md) site. Based on analyses, quantifies injectivity sites, assesses number wells required finally...

In this paper we examine the trade-offs of using or not pressure-relief for a number representative model aquifers. We show that pressure relief increases injectivity and degree to which it injection rates depends on formation characteristics. The net economic benefit costs scheme improvement in CO2 rates. Where there is only slight increase injectivity, results higher costs. However, when are greater significant benefit. For cases examine, 1.7 0.1 times those without relief.
Summary This paper argues that any carbon dioxide (CO2) capacity-estimation method requires a combination of geological, engineering, and economic analyses to provide rigorous capacity estimates. It also the classification estimates should follow concepts in existing SPE Petroleum Resource Management System (PRMS) (SPE 2007) as closely possible. The takes discussion CO2-storage significantly further. aligns storage-capacity definitions more widely accepted PRMS. Numerous authors...
Abstract This paper argues that any capacity estimation method requires a combination of geological, engineering and economic analysis in order to provide rigorous estimates. It also the classification estimates should follow concepts existing SPE Petroleum Resource Management System as closely possible. The Energy & Environmental Research Centre (EERC) (Gorecki et al., 2009) have developed definition "practical storage capacity" parallels petroleum reserves "the quantity hydrocarbons...

Using data provided by government departments industry, we investigated combinations nine emission hubs twelve basins. We also developed a first-pass method for estimating numbers injection wells using numerical reservoir simulation comparisons with actual projects. forms suite studies intended to help formulate...
Abstract In recognition of the importance interpersonal and professional skills, Engineers Australia (EA) have made it an accreditation requirement for all tertiary engineering students to engage with industrial practice throughout their degree. This experience is obtained through work-integrated learning (WIL) activities, including completing relevant internships, participation in site visits, enrolment industry-based (IBL) courses. Even prior COVID-19 pandemic, increasing numbers more...
Summary This paper presents geoengineering and economic sensitivity analyses assessments of the Wunger Ridge flank carbon capture storage (CCS) site. Both economics are needed to derive number wells required inject a certain amount CO2 for given period. A numerical reservoir simulation examines injection rates ranging from 0.5 1.5 million tonnes year 25 years injection. Primary factors affecting ability include permeability, formation fracture gradient, aquifer strength, multiphase flow...
Studies of the cost carbon capture and storage (CCS) frequently make a single set assumptions about characteristics source CO2and injection site (the sink). However, in practice, design whole CCS system will require optimisation involving selecting appropriate pipeline sizes, route, number, type placing wells. This study reports possible project Australia examines effects different parameters designing system. The area surrounding Gladstone, Rockhampton, Stanwell Callide (“Gladrock”) Central...
This paper describes the methodology used to derive economics of CO2 storage in coal with enhanced coalbed methane recovery. A significant difference between seams and saline aquifers is that incrementally recovered natural gas constitutes an additional revenue stream. In case it necessary distinguish CBM (primary recovery), CO2-ECBM (enhanced recovery caused by including injection CO2), incremental (Storage-ICBM). The demonstrated means a study evaluates carbon capture (CCS-ICBM) at Spring...
Abstract This paper presents geo-engineering and economic sensitivity analyses assessments of the Wunger Ridge flank Carbon Capture Storage (CCS) site. A numerical reservoir simulation examines injection rates ranging from 0.5 to 1.5 million tonnes CO2/year. Primary factors affecting ability inject CO2 include permeability, formation fracture gradient, multiphase flow functions. Secondary solubility in brine, well location with respect barriers/low-permeability aquifers, model geometry...
This paper demonstrates the application of an approach to storage capacity estimation using a classification system that closely follows Petroleum Resource Management System (PRMS) recommended by Society Engineers. We apply assessment hypothetical, but representative site in Surat Basin, onshore Australia. The assumes CO2 is captured from sources south Queensland and transported potential site. estimate "Prospective Storage Capacity" between zero 560 million tonnes.
The production and treatment of formation water from CO2 storage formations in south-east Queensland, Australia may have the dual benefits improving injectivity, as well as, proving a supplementary source water. Coal gas-fired plants this region generates about 25 Mt/yr consume approximately 36 GL/yr sedimentary basins area are thought to be injection. This paper suggests that can result significant cost reductions make sites much more prospective. In addition, there opportunities for selling
