Abstract:
Water shortage has become an emerging environmental issue. Reclamation of the effluent from municipal wastewater treatment plant (WWTP) is feasible for meeting the growth of water requirement from industries. In this study, the results of a pilot-plant setting in Futian wastewater treatment plant (Taichung, Taiwan) were presented. Two processes, sand filter – ultrafiltration – reverse osmosis (SF-UF-RO) and sand filter – electrodialysis reversal (SF-EDR), were operated in parallel to evaluate their stability and filtrate quality. It has been noticed that EDR could accept inflow with worse quality and thus required less pretreatment compared with RO. During the operation, EDR required more frequent chemical cleaning (every 3 weeks) than RO did (every 3 months). For the filtrate quality, the desalination efficiency of SF-EDR ranged from 75 to 80% in continuous operation mode, while the conductivity ranged from 100 to 120 μS/cm, with turbidity at 0.8 NTU and total organic carbon at 1.3 mg/L. SF-EDR was less efficient in desalinating the multivalent ions than SF-UF-RO was. However for the monovalent ions, the performances of the two processes were similar to each other. Noticeably, total trihalomethanes in SF-EDR filtrate was lower than that of SF-UF-RO, probably because the polarization effects formed on the concentrated side of the EDR membrane were not significant. At the end of this study, cost analysis was also conducted to compare the capital requirement of building a full-scale wastewater reclamation plant using the two processes. The results showed that using SF-EDR may cost less than using SF-UF-RO, if the users were to accept the filtrate quality of SF-EDR.

Abstract:
An event data recorder (EDR) is a device installed in a vehicle to record information. Similar to a black box in an airplane, an EDR is used in the study of automobile accidents. Many schemes have been proposed that use vehicle network technology to help record EDR data, including schemes involving storing data on roadside units or nearby vehicles and schemes leveraging blockchain technology. However, these schemes do not take into account the vehicle company’s server; with the increased use of autonomous vehicles, the data related to these vehicles are always uploaded to the vehicle company’s server. In this scenario, we classify the situation into different cases, according to whether or not it is an emergency and whether the vehicle and the server are connected. For these cases, we propose a scheme whereby a vehicle uploads the EDR data to a cloud server and sends the evidence of storage to the nearby vehicle through a vehicular ad hoc network. Our scheme offers a fast response due to the use of symmetric cryptography algorithms while also considering security requirements.

Abstract:
Species, dose, and mean ion resident time (MIRTc) in the concentrate of electro-dialysis reversal (EDR) desalination are analysed. In the classical EDR, dimensions, flow, and velocity of dilute and concentrate are equal; Langelier saturation index (LSI) and CaSO4 saturation are used to control the scaling and fouling processes in concentrate, as such LSI<+2.16 for preventing CaCO3 from fouling and CaSO4 saturation level<200 for averting CaSO4 from precipitation. If LSI is more than allowable limit, acid is added in concentrate to keep CaCO3 continuously dissolving; if CaSO4 saturation level in concentrate is more than the allowable limit, sodium hexametaphosphate (SHMP) is added in concentrate to maintain CaSO4 dissolving. EDR, however, was successfully modernised to operate with the higher water recovery rate (R) without any anti-scalant and without acid; this new EDR operated with LSI at 2.29 and CaSO4 saturation level 358.9% at lower dose and lower MIRTc. Dose and MIRTc are proposed to address the controlling process. Monographs for the acids and SHMP requirements, and for the desalting cost including desalting power, membrane surface area, and chemicals usage, are developed. By lowering R and polar reversal interval, EDR can be operated at MIRTc<130 min; at MIRTc<130 min, desalting cost/ energy can be minimised by eliminating chemicals requirement.

Abstract:
The flow upstream of a free overfall from smooth inverted semicircular channels is theoretically analysed to compute the end-depth ratio (EDR), applying an energy equation based on the Boussinesq assumption. This approach eliminates the need for an experimentally determined pressure coefficient. Experiments were conducted with horizontal channel conditions. The EDR related to the critical depth, which occurs upstream from the end section, is found to be around 0.695 for a critical depth-diameter ratio up to 0.40. A simple method is presented to estimate the discharge from a known end-depth. The theoretical model corresponds closely with the experimental data.

Abstract:
SummaryA workflow is defined as a predefined set of work steps and partial ordering of these steps in any environment to achieve the expected outcome. Few studies have investigated the workflow of providers in a dental office. It is important to understand the interaction of dental providers with the existing technologies at point of care to assess breakdown in the workflow which could contribute to better technology designs.The study objective was to assess electronic dental record (EDR) workflows using time and motion methodology in order to identify breakdowns and opportunities for process improvement.A time and motion methodology was used to study the human-computer interaction and workflow of dental providers with an EDR in four dental centers at a large healthcare organization. A data collection tool was developed to capture the workflow of dental providers and staff while they interacted with an EDR during initial, planned, and emergency patient visits, and at the front desk. Qualitative and quantitative analysis was conducted on the observational data.Breakdowns in workflow were identified while posting charges, viewing radiographs, e-prescribing, and interacting with patient scheduler. EDR interaction time was significantly different between dentists and dental assistants (6:20 min vs. 10:57 min, p = 0.013) and between dentists and dental hygienists (6:20 min vs. 9:36 min, p = 0.003).On average, a dentist spent far less time than dental assistants and dental hygienists in data recording within the EDR.

Abstract:
Traditional acid extraction or electrodialytic remediation (EDR) is inefficient to recover phosphorus (P) from incinerated sewage sludge ash (ISSA). This study used a hybrid process including acid extraction and EDR to extract P from ISSA and remove heavy metals/metals from the P extract sequentially. Specifically, the P extract was obtained by extracting ISSA with 0.2 M H2SO4 and a two-compartment cell was applied in the following EDR process. Constant currents of 15 mA, 35 mA and 50 mA were applied for the electromigration of the heavy metals/metals. Results showed that the efficiency of heavy metals/metals removal fluctuated and was relatively low (approximately 20%) under a current of 15 mA. Increasing the current to 35 mA significantly increased the removal efficiency and that of 50 mA was conspicuous, except Fe, Al and As (<50%). Meanwhile, P gradually immigrated to the catholyte after an EDR duration of 96 h. Consistent with heavy metal/metal immigration results, the pH change and 50 mA voltage drop were dramatic (the pH change was 12 and the voltage drop was 11 V). In addition, flocculent precipitates, which were predominantly Ca, P, Al, Mg and Fe, were found in the catholyte.

Abstract:
Abstract In this paper, the hydraulic properties of the finite-crested stepped spillway (FCSS) including discharge coefficient (Cd) and the ratio of energy dissipation (EDR) were experimentally investigated. Results indicated that the Cd of the FCSS changes between 0.9 and 1.2, while the ratio of the upstream head to the length of the crest (hup/Lc) changes between 0.25 and 1.8. The hup/Lc is the main parameter affecting the Cd. The value hup/Lc equal to 0.6 is a good criterion for designing the crest of the FCSS. At this point, the Cd of FCSS is about 1.0. The performance of FCSS regarding the EDR changes between 95 and 40 percent. By increasing the discharge of flow and skimming flow formation, the performance of the FCSS related to energy dissipation is dramatically decreased.

Abstract:

Electronic medical records (EMRs) or electronic health records have been in use for years in hospitals around the world as a time-saving system for patient record keeping. Despite its widespread use, some physicians disagree with the assertion that EMRs save time. The purpose of this study was to explore whether any time saved with the use of the EMR system was actually devoted by doctors to patient-care and thereby to improved patient-care efficiency. The conceptual support for this study was predicated employing the task-technology fit theory. Task-technology theorists argue that information technology is likely to have a positive impact in individual performance and production timeliness if its capabilities match the task that the user must perform. The research questions addressed the use of an EMR system as a time-saving device, its impact on the quality of patient-care, and how it has influenced patients? access to healthcare in Nigeria. In this research, a comparative qualitative case study was conducted involving 2 hospitals in Nigeria, one using EMRs and another using paper-based manual entry. A purposeful sample of 12 patients and 12 physicians from each hospital was interviewed. Data were compiled and organized using Nvivo 10 software for content analysis. Categories and recurring themes were identified from the data. The findings revealed that reduced patients? registration processing time gave EMR-using doctors more time with their patients, resulting in better patient care. These experiences were in stark contrast to the experiences of doctors who used paper-based manual entry. This study supports positive social change by informing decision makers that time saved by implementing EMR keeping may encourage doctors to spend more time with their patients, thus improving the general quality of healthcare in Nigeria.

Full text
Abstract:

Due to stricter emission legislation, there is a need for more efficient control of diesel engines with exhaust gas recirculation(EGR). In particular, it is important to estimate the air/fuel ratio accurately in transients. Therefore a new engine gas flow model has been developed. This model divides the gas into one part for oxygen and one part for inert gases. Based on this model an observer has been designed to estimate the oxygen concentration in the gas going into the engine, which can be used to calculate the air/fuel ratio. This observer can also be used to estimate the intake manifold pressure. The advantage of estimating the pressure, instead of low pass filtering the noisy signal, is that the observer does not cause time delay.

Full text
Abstract:
This study builds on the theory of planned behavior, institutional and innovation diffusion theories to investigate physicians' responses to introduction of electronic medical records (EMR) in large healthcare organizations. Using a case study methodology, we show that physicians' attitudes towards using EMR are influenced by their perceptions of EMR complexity, relative advantage, compatibility with professional beliefs and individual predisposition to change. Specifically, we found that EMR usability characteristics such as system interface, "navigation," "search" and "speed" are major dimensions underlying physicians' perceptions of EMR complexity. To the extent that navigating and searching for clinical results are seen as difficult, physicians' perceptions of the complexity of using EMR are enhanced, with the result of physicians forming more negative attitudes towards EMR and using EMR less. Accessibility to EMR (i.e. logging in) and availability of hardware are two emergent constructs. These factors are immediate barriers for physicians not using EMR or using EMR minimally. At the same time, these barriers contribute to impacting physicians' perceptions that EMR is difficult to use and disadvantageous (i.e. time inefficient) compared to the paper chart. Results also show that most EMR usage at Alpha is rather "shallow." Physicians tend to use data-retrieval EMR minimally, mainly to supplement the paper chart. The availability of this "competing artifact," that is much easier to use and conveniently located near a patient's room limits the extent to which physicians use EMR at Alpha. Use of an imaging EMR system (EMR3) is more committed. EMR3 is used to replace the "old way" of accessing films. Lack of accessibility and hardware barriers, the relative advantage of EMR3 and other system usability considerations contribute to physicians using this system more faithfully. As regards the question "what do physicians want?" it seems that physicians want a system that that is easy to access and simple to use but most importantly, a system that they can directly identify with, an EMR that is personally relevant. In order to promote a "deeper" level of EMR usage, the benefits of EMR need to be emphasized to physicians while any potential costs or barriers reduced or eliminated.

Abstract:

Because of new emission and on board diagnostics legislations, heavy truck manufacturers are facing new challenges when it comes to improving the engines and the control software. Accurate and real time executable engine models are essential in this work. One successful way of lowering the NOx emissions is to use Exhaust Gas Recirculation (EGR). The objective of this thesis is to create a mean value model for Scania's next generation EGR system consisting of a poppet valve and a two stage cooler. The model will be used to extend an existing mean value engine model. Two models of different complexity for the EGR system have been validated with sufficient accuracy. Validation was performed during static test bed conditions. The resulting flow models have mean relative errors of 5.0% and 9.1% respectively. The temperature model suggested has a mean relative error of 0.77%.

Não esquecendo um enquadramento livre sobre o pensamento de vários autores a partir do século XIX com Karl Marx, e, evocando o actual contexto marcado pela globalização e pela rápida expansão de novas tecnologias de informação e de comunicação que mudaram o nosso dia-a-dia, esta tese procura estudar e discutir as consequências sócio-organizacionais da utilização de EDI – electronic data interchange. Atendendo ao tipo de mudanças em questão, é dado um destaque à reengenharia de processos: uma forma de mudança organizacional que considera a tecnologia de informação como uma ferramenta importante. Para efeitos deste estudo, utilizando várias ferramentas de recolha de dados, efectua-se uma incursão empírica focalizada no sector editorial português, abordando de forma inédita as relações entre as empresas que o integram e os seus grandes clientes, ou seja, as grandes cadeias de distribuição. Além da obrigatória caracterização deste sector, trata-se designadamente de entrar no “universo” - relativamente desconhecido e potencialmente polémico - das interacções entre este tipo de fornecedores e clientes, do poder relativo entre ambos e das possíveis transformações que a adopção do EDI acarreta para as organizações. São tratados os motivos pelos quais as editoras adoptam esta forma de integração electrónica com os clientes
Without neglecting a free interpretation on the thinking of several authors from the 19th century, starting with Karl Marx, and taking into account the current circumstances influenced by globalization and rapid spread of new information and communication technologies that have changed our daily life, this thesis seeks to study and discuss the socio-organizational consequences of the use of EDI - electronic data interchange. Given the nature of this change, it is given a special emphasis on business process reengineering: a way of organizational change that considers information technology as an important tool. For the purposes of this study, using various tools for data collection, it will be carried out an empirical incursion focused on the Portuguese editorial sector, addressing by an unprecedented way the relations between companies that integrate that sector and its major customers, i.e. the large distribution chains. In addition to the required sector‟s characterization, this work namely goes towards the "universe"- relatively unknown and potentially controversial – made of interactions between such suppliers and customers, of the relative power between both of them and of the possible transformations that the adoption of EDI carries to organizations. This analysis includes the reasons why publishers use EDI.

Abstract:

A significant amount of evidence existed in support of the positive effect on the quality of healthcare that resulted from transitioning to electronic health information systems, equally compelling evidence suggests that the development process for electronic health information systems falls short of achieving its potential. The objective of this research was to assess the existing HIT standards and health information management (HIM) principles to determine if they are robust enough to inform the development of national and international interoperability standards. The research question asked; How do HIT standards and HIM principles and practices influence the quality of EHR performance? This study’s goal was to maintain focus on the collaborative challenges revealed by the lack of understanding and shared vision that commonly exists between HIM professionals, HIT developers, and HIT vendors that obstruct synergy and enfolding of health information standards-based capabilities and HIM practice (business) standards. The complex electronic health record (EHR) universe proved well suited for testing by a combination of complexity science and the unified theory of acceptance and use of technology (UTAUT) information management theories. Through analysis of research literature and qualitative interviews, the research identified nine factors defined into drivers and barriers that influenced the actions of healthcare organizations; leadership, patient focus, planning, communication, alignment with lifecycle models people, processes, dynamics, training and user input, change management standard adoption, and recognition of the power of technology. Analysis of the data obtained from exploratory qualitative interviews of health information technology professionals selected from a professional healthcare management organization supported conclusions that leadership, collaboration, planning, and training limiters, have a direct impact on EHR system success or failure.

Abstract:
AbstractEducation digital storytelling (EDS) refers to digital storytelling in education. EDS is often presented as a technology-enhanced learning approach with powerful educational benefits. The use of EDS as a tool to support students to consider and pursue a meaningful life based on their interests, talents, and aspirations is spreading. Due to its nature, EDS could be an optimal tool to create and share digital stories to stimulate career plans. This paper deals with the educational uses of digital storytelling and presents an overview of how EDS can be used to support career guidance. It concludes with a brief description of the NEFELE Erasmus+ project that will implement tangible user interfaces (TUIs) in the classrooms to promote the EDS as a tool for career intervention.

Abstract:
Abstract The objective of the paper is to describe the application of artificial intelligence software to predict formation evaluation logs (compressional sonic, shear sonic and density) using only gamma ray, and resistivity log data and drilling dynamics data as received by the electronic drilling recorder (EDR). The software was applied real-time as a well was being drilled in deepwater Gulf of Mexico. Thorough examination and conditioning of EDR and wireline data give way to a training model construction for the artificial neural network (ANN) using full suites of log-data in offset wells. Next, a neural network architecture and associated hyperparameters are chosen and tested. The fully trained and validated model is applied to the gamma ray, resistivity and EDR of the target well while drilling. Real-time EDR and wireline data flow via WITSML from rig to cloud and data is delivered to the client. The results of the study indicate the simulated log data were comparable to those measured from conventional logging tools over the study area. In both blind well tests the density agreed with the conventional log results within 1.1 % and the compressional within 2.51 % (Figure 1). Each of these is well within the range of variance expected of repeat runs of a conventional logging tool. A primary driver for near real-time logs was to confirm structural depth of the target sands along the well bore. There was a depleted sand below the expected TD of the well that, if encountered, could have led to total losses and possible loss of the wellbore. It was critical to have real-time logs to characterize the sands above the depleted sand, using every possible petrophysical and geologic character to refine the log correlation. This integration of all the logs provided the best interpretation of the sand quality and led toward the completion decision. AI-based logs are a highly cost-effective alternative to LWD logging. It presents an environmentally friendly approach as there is no logging personnel on-site and no expensive and potentially dangerous nuclear sources in the hole The deployment of this patented, machine learning-driven, real-time simulation of formation evaluation logs is unique in using only gamma ray, resistivity and drilling data. It is particularly useful in the overburden section where formation evaluation tools are often not run for cost reasons, in side-tracks, in HP/HT settings and operational risk mitigation. It provides additive data for other petrophysical/QI/rock property analyses including seismic inversion, shale content, porosity, log QC/editing, real-time LWD, drilling optimization, etc.

Abstract:
Abstract Polymer flooding projects require hundreds of ppm of polymer (often HPAM) to viscosify the injection water. It is well known that the required dose of HPAM to obtain a targeted viscosity will decrease by reducing the salinity of the inlet water. When the water salinity is low enough, desalination of water for reducing the required polymer concentration brings effective cost savings. In a scenario where the produced water has a salinity of 6 g/L, desalination of this water down to 1 g/L before polymer injection would reduce by half polymer consumption (from 1300 ppm down to 700 ppm). Such low salinity can be found in many existing polymer flooding projects in sandstones reservoirs. A lower concentration of polymer leads to significant reductions of CAPEX (storage tank, pump size) and OPEX (polymer cost, transport and handling). But there are also indirect advantages and cost savings impact of low incoming Polymer concentration in polymer flooding projects. Polymer flooding technology increases and accelerates the oil production by a so-called piston effect pushing an oil bank and enhancing conformance in the reservoir. But there are issues relative to polymer production such as lower separation efficiency, thermal clogging of the polymer in the heat exchangers and poor performance of produced water treatment due to the presence of polymer. It was proven that the impact on water treatment performance is directly related to the concentration of polymer in the produced water. To reduce this impact, existing technical solutions (such as mechanical or chemical degradation, separation by centrifugation) are costly. The presence of polymer is very detrimental to any filtration technologies (membrane fouling) and therefore Oil in Water reduction below 20 ppm is becoming challenging. Waiting for suitable cost effective water treatment technologies, existing polymer flooding projects have adopted a different strategy aiming at reducing or stopping polymer solution injection when the back produced polymer concentration was about to reach a limit known to impact the existing water treatment. Using the EDR technology to reduce required polymer concentration will thus reduce the back produced polymer concentration and could allow the existing water treatment technologies to handle back produced polymer without additional modification and cost. EDR adaptation to desalination of produced water in presence of polymer, dispersed oil, and production chemicals was performed by Total, MemBrain and MEGA. The development of suitable membrane and stack withstanding up to 80°C was engineered by MemBrain and tested during a few weeks on synthetic produced water on a semi-industrial scale pilot treating 10 m3/h synthetic water (in closed loop) with an EDR stack containing 29.2 m2 membrane area. After a few reference tests for characterizing the EDR stack performances, the pilot was operated during 1 month in presence of a salt matrix representative of the case study: 6 g/l of salt, 600 mg/l HPAM polymer, 20 mg/L crude oil, 50 mg/L corrosion inhibitor and 20 mg/l anti-scalant. Voltage was set at 1 V/pair (100 V). The temperature was set at 60°C with no impact on the membrane stack reliability during the test. The presence of HPAM slightly decreases desalination rate but no fouling was observed. Cost and environmental evaluations showed that EDR improves all the indicators. The total technical cost of the project is lower with EDR (CAPEX higher but lower OPEX) compared to a base case without any desalination. The next step is to qualify the technology on a site pilot with real produced water.

Abstract:
Abstract After drilling in the Gulf area of Middle East for approximately nine months, the operation’s project team struggled to find a consistent and repeatable roadmap for significant rate of penetration (ROP) improvements. The team was relying on the driller to manually control the ROP, weight on bit (WOB), differential pressure, pump pressure, and torque. Regardless of the driller’s experience, it is difficult for a single person to successfully monitor and adjust for multiple and continuously changing variables in real time. Extreme variation and lack of control on drilling parameters (such as WOB, torque, and differential pressure) prevented repeatable ROP improvements, despite having a sound drilling plan. To solve this problem, the team tasked a third party to 1) deploy its electronic drilling recorder (EDR) to improve data quality, 2) integrate its multi-parameter DAS™ system into the rig’s programmable logic controls (PLC) system, and 3) deploy drilling optimization software solutions in real time. The overall objective was to build a decision-supporting tool to overcome the main ROP limiters through proper identification and mitigation, thus yielding higher ROP and creating newly optimized drilling parameters for future wells. A pilot program consisting of two rigs and six wells per rig (12 wells in total) was executed utilizing this new approach. Over each section of each well, the team followed a traditional continuous improvement cycle of "Identify– Plan – Execute – Review". The EDR was able to accurately identify and record the drilling control limits (such as for ROP, WOB, torque, or differential pressure). The DAS system was also able to demonstrate improved control of WOB, ROP and, torque limits, and target differential pressures. Delivering this information in real time encouraged conversations around modifications to the existing well plan. During post-well analysis, the data allowed the optimization team to clearly identify the limiter of each hole section for changes in future well planning. A flexible dashboard platform was utilized to assist the optimization team by developing enhanced graphics to improve the visibility and accuracy of the real-time performance monitoring. These dashboards target critical operations and allow more data to be taken into consideration, thus providing a more holistic and structured decision-making process. The pilot program showed measurable improvement in several areas. Overall, on-bottom ROP improved by 10.5%, shoe track drill-out times were reduced by 31%, and physical inspections showed significant reductions in bit wear. Additionally, the higher quality of data recording contributed to a noticeable improvement on processing multiple data-analytics modules. This paper describes the challenges and step-by-step chronology of solutions deployed to achieve continuous improvement and to maximize ROP by effectively focusing on process execution. The knowledge required to execute a fit-for-purpose drilling optimization plan was the objective to the solution described in this work. This paper also provides a holistic view of the entire drilling system, along with insight into drilling parameters that can improve efficiency from planning to the execution phase.

Abstract:
Abstract The objective of this study is to present a novel rock formation identification model using a data-driven modeling approach. This study explores the use of real-time drilling data to train and validate a classification model to improve the efficiency of the drilling process by reducing Mechanical Specific Energy (MSE). In this study, we demonstrate the feasibility of a layer-based determination and change detection of properties of rock formation currently being drilled as accurately and fast as possible. Data for this study was collected from a custom-built lab-scale drilling rig equipped with multiple sensors. The experiment was conducted by drilling through an arrangement of different rock formations of varying rock strength properties. Data was recorded and stored at a frequency of 2 kHz, then filtered, processed, and downsampled to extract relevant features. This dataset was used to train an Artificial Neural Network and other machine learning classification algorithms. Feature selection was made first with ten most notable features found by Random Forest, and the second set with derived measurements and down-sampled dynamic features from the sensors. The classification analysis was divided into two steps: the best predictors/features extraction and classification model building. The models were trained using multiple classification algorithms, namely logistic regression, linear discriminant analysis (LDA), Support Vector Machines (SVM), Random Forest (RF), and Artificial Neural Networks (ANN). It was found that random forest and ANN performed the best with prediction accuracy of 99.48% and 99.58%, respectively, for the data set with ten most prominent features. The high prediction rate accuracy for the most prominent predictors suggests that if the high-frequency data can be processed in real-time, predicting what formation we are drilling in is possible to achieve in near real-time. This can lead to significant savings for drilling companies as optimal drilling parameters can be computed, and in turn, optimized Mechanical Specific Energy can be obtained in real-time. Since the rock formation identification is time-consuming, we also describe here an alternative approach using slightly less accurate but equally powerful dynamic predictors. In this case, we show that our dynamic predictor models with RF and ANN yielded prediction accuracy of 96.30% and 95.61%, respectively. Both the prominent feature and dynamic predictor approaches are described in detail in this paper. Our results suggest that accurately predicting rock formation type in real-time while drilling is very much feasible with lesser computational cost and complexity. This study provides the building blocks for the development of a completely autonomous downhole device and Electronic Device Recorders (EDR) that reduces the need for highly sophisticated sensors or data transmission processes downhole.

Abstract:
Abstract Unconventional reservoir plays an increasingly important role in the world energy system, but its recovery is always quite low. Therefore, the economic and effective enhanced oil recovery (EOR) technology is urgently required. Moreover, with the aggravation of greenhouse effect, carbon neutrality has become the human consensus. How to sequestrate CO2 more economically and effectively has aroused wide concerns. Carbon Capture, Utilization and Storage (CCUS)-EOR is a win-win technology, which can not only enhance oil recovery but also increase CO2 sequestration efficiency. However, current CCUS-EOR technologies usually face serious gas channeling which finally result in the poor performance on both EOR and CCUS. This study introduced CO2 electrochemical conversion into CCUS-EOR, which successively combines CO2 electrochemical reduction and crude oil electrocatalytic cracking both achieves EOR and CCUS. In this study, multiscale experiments were conducted to study the effect and mechanism of CO2 electrochemical reduction for CCUS-EOR. Firstly, the catalyst and catalytic electrode were synthetized and then were characterized by using scanning electron microscope (SEM) & energy dispersive X-ray spectroscopy (EDS) and X-ray photoelectron spectroscopy (XPS). Then, electrolysis experiment & liquid-state nuclear magnetic resonance (1H NMR) experiments were implemented to study the mechanism of CO2 electrochemical reduction. And electrolysis experiment & gas chromatography (GC) & viscosity & density experiments were used to investigate the mechanism of crude oil electrocatalytic cracking. Finally, contact angle and coreflooding experiments were respectively conducted to study the effect of the proposed technology on wettability and CCUS-EOR. SEM & EDS & XPS results confirmed that the high pure SnO2 nanoparticles with the hierarchical, porous structure, and the large surface area were synthetized. Electrolysis & 1H NMR experiment showed that CO2 has converted into formate with the catalysis of SnO2 nanoparticles. Electrolysis & GC & Density & Viscosity experiments indicated that the crude oil was electrocatalytically cracked into the light components (&lt;C20) from the heavy components (C21∼C37). As voltage increases from 2.0V to 7.0V, the intensity of CO2 electrocchemical reduction and crude oil electrocatalytic cracking enhances to maximum at 3.5V (i.e., formate concentration reaches 6.45mmol/L and carbon peak decreases from C17 to C15) and then weakens. Contact angle results indicated that CO2 electrochemical reduction and crude oil electocatalytic cracking work jointly to promote wettability alteration. Thereof, CO2 electrochemical reduction effect is dominant. Coreflooding results indicated that CO2 electrochemical reduction technology has great potential on EOR and CCUS. With the SnO2 catalytic electrode at optimal voltage (3.5V), the additional recovery reaches 9.2% and CO2 sequestration efficiency is as high as 72.07%. This paper introduced CO2 electrochemical conversion into CCUS-EOR, which successfully combines CO2 electrochemical reduction and crude oil electrocatalytic cracking into one technology. It shows great potential on CCUS-EOR and more studies are required to reveal its in-depth mechanisms.

Full text
Abstract:
A partitioning inter-well tracer test (PITT) determines the residual (or even remaining) oil saturation (SOR) in the flooded region between well-pairs. This type of tracer test can be used to identify improved oil recovery (IOR) targets, evaluate IOR projects, evaluate enhanced oil recovery (EOR) methods, and improve reservoir description for efficient hydrocarbon production. Thus, the main objective of the work with inter-well oil/water partitioning tracers developed within the framework of the IOR Centre is to provide tools and methodologies to improve reservoir description for efficient management of resources. The present report aims to provide insight to its users on the deployment of tracer technology in the inter- well region of water-flooded reservoirs to determine SOR. In turn, this parameter can be used as basis to evaluate the efficiency of several oil-production related operations. It will explain workflows, expertise, and tools needed as well as the importance of the information obtained, and methods to obtain it. This report is directed towards operators, primarily to reservoir engineers and reservoir managers, and service companies, particularly those already engaged on the deployment of tracer technology or those who aim to begin this activity. R&D personnel working in both operators and service companies may also benefit from the contents of the present report.
