The document summarizes two papers on NOx abatement techniques for marine applications using selective catalytic reduction (SCR) systems. Paper I studied how sulfur dioxide, water, and low temperatures affect SCR catalyst performance. It found that SO2 and water can both decrease NOx reduction at high concentrations, low temperatures, and high space velocities. Paper II identified challenges with SCR installations regarding incentives, design issues, urea quality, and lack of operator training. Overall, SCR can efficiently reduce NOx but risks of deactivation need to be avoided through proper system design, operation, and training. Future work should study different urea types and varying diesel exhaust compositions.

Does Heavy Oil Recovery Need Steam?
Heavy Oil recovery traditionally starts with depletion drive and (natural) waterdrive with very low recoveries as a result. As EOR technique, steam injection has been matured since the 1950s using CSS (cyclic steam stimulation), steam drive or steam flooding, and SAGD (steam assisted gravity drainage). The high energy cost of heating up the oil bearing formation to steam temperature and the associated high CO2 footprint make steam based technology less attractive today and many companies in the industry have been actively trying to find alternatives or improvements. As a result there are now many more energy efficient recovery technologies that can unlock heavy oil resources compared with only a decade ago. This presentation will discuss breakthrough alternatives to steam based recovery as well as incremental improvement options to steam injection techniques. The key message is the importance to consider these techniques because steam injection is costly and has a high CO2 footprint

The Intersection of Environment and EOR: How Carbon Capture is Changing Terti...Society of Petroleum Engineers
Increasing interest by governments worldwide on reducing CO2 released into the atmosphere form a nexus of of opportunity with enhanced oil recovery which could benefit mature oil fields in nearly every country. Overall approximately two-thirds of original oil in place (OOIP) in mature conventional oil fields remains after primary or primary/secondary recovery efforts have taken place. CO2 enhanced oil recovery (CO2 EOR) has an excellent record of revitalizing these mature plays and can dramatically increase ultimate recovery. Since the first CO2 EOR project was initiated in 1972, more than 154 additional projects have been put into operation around the world and about two-thirds are located in the Permian basin and Gulf coast regions of the United States. While these regions have favorable geologic and reservoir conditions for CO2 EOR, they are also located near large natural sources of CO2.
In recent years an increasing number of projects have been developed in areas without natural supplies, and have instead utilized captured CO2 from a variety of anthropogenic sources including gas processing plants, ethanol plants, cement plants, and fertilizer plants. Today approximately 36% of active CO2 EOR projects utilize gas that would otherwise be vented to the atmosphere. Interest world-wide has increased, including projects in Canada, Brazil, Norway, Turkey, Trinidad, and more recently, and perhaps most significantly, in Saudi Arabia and Qatar. About 80% of all energy used in the world comes from fossil fuels, and many industrial and manufacturing processes generate CO2 that can be captured and used for EOR. In this 30 minute presentation a brief history of CO2 EOR is provided, implications for utilizing captured carbon are discussed, and a demonstration project is introduced with an overview of characterization, modeling, simulation, and monitoring actvities taking place during injection of more than a million metric tons (~19 Bcf) of anthropogenic CO2 into a mature waterflood.
Longer versions of the presentation can be requested and can cover details of geologic and seimic characterization, simulation studies, time-lapse monitoring, tracer studies, or other CO2 monitoring technologies.

Geochemical logging provides quantitative estimates of formation mineralogy through measurements of elemental abundances. This allows for improved evaluation of complex reservoirs containing multiple minerals. Case studies demonstrated how geochemical logs aided in characterizing carbonate, sandstone, and shale gas formations through mineral identification, matrix density calculation, and porosity/saturation determinations. Core-log integration can be challenging due to differences in sampling volumes, but geochemical logs provide valuable mineralogical context for formation evaluation.

Improving Reservoir Simulation Modeling with Seismic Attributes
This document summarizes a presentation on improving reservoir simulation modeling with seismic attributes. It discusses how seismic interpretation provides information on stratigraphy, facies distribution, and reservoir properties through attributes. Seismic attributes can help with horizon and fault interpretation when seismic signals are poor. They are also used for facies and property modeling to distribute lithology and properties between wells and in un-drilled areas. Integrating seismic attributes into reservoir modeling can significantly improve dynamic models, simulations, and production forecasts.

This document discusses strategies for reducing sulfur emissions from ships to meet new regulations. It outlines options for using lower sulfur fuels or installing exhaust gas cleaning systems (scrubbers) on ships. Scrubbers can effectively reduce sulfur emissions by cleaning exhaust gases but require space, add weight, and generate wastes. Selecting fuel and abatement technologies involves considering multiple technical, economic, environmental and logistical factors. Scrubbers are an emerging technology that provides a means to reduce sulfur emissions while continuing to use high-sulfur fuel, but have drawbacks to consider regarding their impacts and costs.

Saline Aquifer Storage Performance at the Quest CCS Project
As one of a handful of large-scale CCS projects currently injecting CO2 into a dedicated saline aquifer storage site, Shell’s Quest project offers a unique case study into the performance of dedicated storage. The Quest project injects CO2 into the Basal Cambrian Sandstone located 2 km below the surface. After the first year of operations, the Quest reservoir has exceeded internal expectations. While the original premise called for eight wells, today only two of three constructed injection wells take 100 per cent of project volumes (~140 tonnes /hr).
In this webinar, Simon O’Brien, Shell Quest Subsurface Manager, discussed storage performance at Quest after one year of operations as well as early results from the measurement, monitoring, and verification (MMV) plan. Download-manuals-water quality-wq-training-44howtomeasuresodium

CarbonNet storage site characterisation and selection process
The CarbonNet Project has undertaken an extensive geoscience evaluation programme to identify, characterise and select prospective offshore storage sites in the nearshore Gippsland Basin, in south eastern Australia.
The process builds upon basin and regional assessments undertaken at the national level, and focuses upon leads and play fairs assessed using a vast amount of geological data available from 50 years of petroleum exploration and developments in the basin.
CarbonNet geoscience work has been subject to independent scientific peer reviews, and external assurance certification by Det Norske Veritas against the recommended practise for geological storage of carbon dioxide (CO2) J203.
CarbonNet now holds five greenhouse gas assessments permits providing exclusive rights to explore, appraisal and develop a portfolio of CO2 storage sites.
The project has identified a prioritised storage site capable of storing in excess of 125 Mt of CO2 for which a 'Declaration of Storage' has been prepared which demonstrates the 'fundamental determinants' and probability assessment of potential CO2 plume paths as required under Australian CCS legislation'.
This webinar will be presented by Dr Nick Hoffman, CarbonNet Geosequestration Advisor, and will provide an overview of CarbonNet geoscience evaluation programme, referencing the relevant knowledge share products available on the Global CCS Institute website.
Borehole Seismic Solutions for Integrated Reservoir Characterization and Moni...
Borehole Seismic Solutions for Integrated Reservoir Characterization and Moni...Society of Petroleum Engineers
Modern oil and gas field management is increasingly reliant on detailed and precise 3D reservoir characterisation, and timely areal monitoring. Borehole seismic techniques bridge the gap between remote surface-seismic observations and downhole reservoir evaluation: Borehole seismic data provide intrinsically higher-resolution, higher-fidelity images than surface-seismic data in the vicinity of the wellbore, and unique access to properties of seismic wavefields to enhance surface-seismic imaging. With the advent of new, operationally-efficient very large wireline receiver arrays; fiber-optic recording using Distributed Acoustic Sensing (DAS); the crosswell seismic reflection technique, and advanced seismic imaging algorithms such as Reverse Time Migration, a new wave of borehole seismic technologies is revolutionizing 3D seismic reservoir characterization and on-demand reservoir surveillance. New borehole seismic technologies are providing deeper insights into static reservoir architecture and properties, and into dynamic reservoir performance for conventional water-flood production, EOR, and CO2 sequestration – in deepwater, unconventional, full-field, and low-footprint environments. This lecture will begin by illustrating the wide range of borehole seismic solutions for reservoir characterization and monitoring, using a diverse set of current- and recent case study examples – through which the audience will gain an understanding of the appropriate use of borehole seismic techniques for field development and management. The lecture will then focus on DAS, explaining how the technique works; its capability to deliver conventional borehole seismic solutions (with key advantages over geophones); then describing DAS’s dramatic impact on field monitoring applications and business-critical decisions. New and enhanced borehole seismic techniques – especially with DAS time-lapse monitoring – are ready to deliver critical reservoir management solutions for your fields.GRS Winter 2011 Brochure

Incorporating Numerical Simulation Into Your Reserves Estimation Process: A P...Society of Petroleum Engineers
Reservoir simulation is a sophisticated technique of forecasting future recoverable volumes and production rates that is becoming commonplace in the management and development of oil and gas reservoirs, small and large. Calculation and estimation of reserves continues to be a necessary process to properly assess the value and manage the development of an oil and gas producer’s assets. These methods of analysis, while generally done for different purposes, require knowledge and expertise by the analyst (typically a reservoir engineer) to arrive at meaningful and reliable results. Increasingly, the simulation tool is being incorporated into the reserves process. However, as with any reservoir engineering technique, certain precautions must be taken when relying on reservoir simulation as the means for estimating reserves. This discussion highlights some of the important facets one should consider when applying numerical simulation methods to use for, or augment, reserves estimates. The main take away will be an appreciation for the areas to focus on to arrive at meaningful and defendable estimates of reserves that are based on reservoir models.Illuminating Insights Into Well and Reservoir Optimisation Using Fibre-optic...
Illuminating Insights Into Well and Reservoir Optimisation Using Fibre-optic...Society of Petroleum Engineers
In these times of low oil and gas prices, the drive to provide 'more for less' has never been greater. One key component in achieving this is the ability to accurately monitor the production rates along a wellbore and across a reservoir. Ideally a range of different measurements should be available on-demand from all points in all wells. Clearly conventional sensors such as downhole pressure and temperature gauges, flow meters, geophone arrays and production logging tools can provide part of the solution but the cost of all these different sensors limits their widespread deployment. Fibre-optic Distributed Acoustic Sensing, or DAS for short, is changing that. Using an optical fibre deployed in a cable from surface to the toe of a well DAS, often in combination with fibre-optic Distributed Temperature Sensing (DTS), provides a means of acquiring high resolution seismic, acoustic and temperature data at all points in real-time. Since the first downhole demonstrations of DAS technology in 2009 there has been rapid progress in developing the technology and applications, to the point where today it is being used to monitor the efficiency of hydraulic fracture treatments, provides continuous flow profiling across the entire wellbore and is used as a uniquely capable tool for borehole seismic acquisition. With optical fibre installed in your wells and DAS acquiring data, there is now the ability to cost effectively and continuously monitor wells and reservoirs to manage them in real-time in order to optimise production.

"Deepwater Managed Pressure Drilling and Well Drillability, Efficiency and Pr...Society of Petroleum Engineers
Adoption of the applied surface-backpressure types of managed pressure drilling (MPD) technologies in deepwater have mainly involved the use of a rotating control device (RCD). The RCD creates a closed drilling system in which the flow out of the well is diverted towards an automated MPD choke manifold (with a high-resolution mass flow meter) that aside from regulating backpressure also increases sensitivity and reduces reaction time to kicks, losses, and other unwanted drilling events. This integration of MPD equipment into floating drilling rigs to provide them with MPD capabilities, including the capacity to perform pressurized mud cap drilling (PMCD) and riser gas mitigation (RGM), has produced improvements not only in drillability and efficiency, but most importantly in process safety. Case histories on how MPD has performed will be presented on the following: • allowed drilling to reach target depth in rank wildcat deepwater wells that have formations prone to severe circulation losses and narrow mud weight windows; • increased drilling efficiency by minimizing non-productive time associated with downhole pressure-related problems and by allowing for the setting of deeper casing seats; • enhanced operational and process safety by allowing for immediate detection of kicks, losses and other critical downhole events. • provided riser gas mitigation capabilities that can detect a gas influx once it enters the drilling fluid stream, and not after it has already broken out above the rig blow-out preventers (BOPs).Cosan Ayan
The document summarizes a presentation on using wireline formation testing (WFT) to characterize reservoirs and reduce uncertainties. It discusses how WFT can be used to measure pressures, sample and analyze downhole fluids, conduct transient tests, and test in-situ stresses. The results from these WFT analyses can be integrated into reservoir modeling workflows and help understand properties like permeability, fluid contacts, and the safe drilling window. Advanced sensors and improved transient testing capabilities in new generation WFT tools are providing more downhole data to reduce risks in reservoir evaluation.

Coiled Tubing Real-Time Monitoring: A New Era of Well Intervention and Worko...Society of Petroleum Engineers
Coiled tubing is a unique fluid and tool conveyance means used to intervene throughout the entire well lifetime. Its flexibility of use is certainly one of the largest in the oil-and-gas industry, ranging from logging to stimulation to cleanout and even drilling. However, for the longest time, it was only seen as a rudimentary fluid conveyance system, despite its capability to service any well deviation.
With the development of instrumented tools for downhole point measurements and the use of fiber optics for distributed sensing, the recent advent of coiled tubing real-time monitoring has completely transformed this image. The access to live wellbore information—such as pressure, temperature, or flow—along with accurate depth control thanks to casing collar locator and gamma ray sensors have greatly enhanced fluid placement. Meanwhile, the ability to monitor the load, torque, and accelerations the bottomhole assembly is subjected to significantly improves the performance and possibility to use and manipulate downhole tools. Thanks to real-time monitoring, a whole new realm of optimization possibility was discovered.
This lecture describes the various real-time measurements that are available today during coiled tubing interventions and how they can be used to provide the industry with faster, safer, and more efficient operations while maximizing return on investment. A wide range of applications and examples will be discussed. Through them, one will be able to appreciate how coiled tubing has now entered a new era where the limits of operational optimization still have not been reached.

CarbonNet geoscience work has been subject to independent scientific peer reviews, and external assurance certification by Det Norske Veritas against the recommended practise for geological storage of carbon dioxide (CO2) J203.
CarbonNet now holds five greenhouse gas assessments permits providing exclusive rights to explore, appraisal and develop a portfolio of CO2 storage sites.
The project has identified a prioritised storage site capable of storing in excess of 125 Mt of CO2 for which a 'Declaration of Storage' has been prepared which demonstrates the 'fundamental determinants' and probability assessment of potential CO2 plume paths as required under Australian CCS legislation'.
This webinar will be presented by Dr Nick Hoffman, CarbonNet Geosequestration Advisor, and will provide an overview of CarbonNet geoscience evaluation programme, referencing the relevant knowledge share products available on the Global CCS Institute website.
Borehole Seismic Solutions for Integrated Reservoir Characterization and Moni...
Borehole Seismic Solutions for Integrated Reservoir Characterization and Moni...Society of Petroleum Engineers
Modern oil and gas field management is increasingly reliant on detailed and precise 3D reservoir characterisation, and timely areal monitoring. Borehole seismic techniques bridge the gap between remote surface-seismic observations and downhole reservoir evaluation: Borehole seismic data provide intrinsically higher-resolution, higher-fidelity images than surface-seismic data in the vicinity of the wellbore, and unique access to properties of seismic wavefields to enhance surface-seismic imaging. With the advent of new, operationally-efficient very large wireline receiver arrays; fiber-optic recording using Distributed Acoustic Sensing (DAS); the crosswell seismic reflection technique, and advanced seismic imaging algorithms such as Reverse Time Migration, a new wave of borehole seismic technologies is revolutionizing 3D seismic reservoir characterization and on-demand reservoir surveillance. New borehole seismic technologies are providing deeper insights into static reservoir architecture and properties, and into dynamic reservoir performance for conventional water-flood production, EOR, and CO2 sequestration – in deepwater, unconventional, full-field, and low-footprint environments. This lecture will begin by illustrating the wide range of borehole seismic solutions for reservoir characterization and monitoring, using a diverse set of current- and recent case study examples – through which the audience will gain an understanding of the appropriate use of borehole seismic techniques for field development and management. The lecture will then focus on DAS, explaining how the technique works; its capability to deliver conventional borehole seismic solutions (with key advantages over geophones); then describing DAS’s dramatic impact on field monitoring applications and business-critical decisions. New and enhanced borehole seismic techniques – especially with DAS time-lapse monitoring – are ready to deliver critical reservoir management solutions for your fields.GRS Winter 2011 Brochure

Incorporating Numerical Simulation Into Your Reserves Estimation Process: A P...Society of Petroleum Engineers
Reservoir simulation is a sophisticated technique of forecasting future recoverable volumes and production rates that is becoming commonplace in the management and development of oil and gas reservoirs, small and large. Calculation and estimation of reserves continues to be a necessary process to properly assess the value and manage the development of an oil and gas producer’s assets. These methods of analysis, while generally done for different purposes, require knowledge and expertise by the analyst (typically a reservoir engineer) to arrive at meaningful and reliable results. Increasingly, the simulation tool is being incorporated into the reserves process. However, as with any reservoir engineering technique, certain precautions must be taken when relying on reservoir simulation as the means for estimating reserves. This discussion highlights some of the important facets one should consider when applying numerical simulation methods to use for, or augment, reserves estimates. The main take away will be an appreciation for the areas to focus on to arrive at meaningful and defendable estimates of reserves that are based on reservoir models.Illuminating Insights Into Well and Reservoir Optimisation Using Fibre-optic...
Illuminating Insights Into Well and Reservoir Optimisation Using Fibre-optic...Society of Petroleum Engineers
In these times of low oil and gas prices, the drive to provide 'more for less' has never been greater. One key component in achieving this is the ability to accurately monitor the production rates along a wellbore and across a reservoir. Ideally a range of different measurements should be available on-demand from all points in all wells. Clearly conventional sensors such as downhole pressure and temperature gauges, flow meters, geophone arrays and production logging tools can provide part of the solution but the cost of all these different sensors limits their widespread deployment. Fibre-optic Distributed Acoustic Sensing, or DAS for short, is changing that. Using an optical fibre deployed in a cable from surface to the toe of a well DAS, often in combination with fibre-optic Distributed Temperature Sensing (DTS), provides a means of acquiring high resolution seismic, acoustic and temperature data at all points in real-time. Since the first downhole demonstrations of DAS technology in 2009 there has been rapid progress in developing the technology and applications, to the point where today it is being used to monitor the efficiency of hydraulic fracture treatments, provides continuous flow profiling across the entire wellbore and is used as a uniquely capable tool for borehole seismic acquisition. With optical fibre installed in your wells and DAS acquiring data, there is now the ability to cost effectively and continuously monitor wells and reservoirs to manage them in real-time in order to optimise production.

"Deepwater Managed Pressure Drilling and Well Drillability, Efficiency and Pr...Society of Petroleum Engineers
Adoption of the applied surface-backpressure types of managed pressure drilling (MPD) technologies in deepwater have mainly involved the use of a rotating control device (RCD). The RCD creates a closed drilling system in which the flow out of the well is diverted towards an automated MPD choke manifold (with a high-resolution mass flow meter) that aside from regulating backpressure also increases sensitivity and reduces reaction time to kicks, losses, and other unwanted drilling events. This integration of MPD equipment into floating drilling rigs to provide them with MPD capabilities, including the capacity to perform pressurized mud cap drilling (PMCD) and riser gas mitigation (RGM), has produced improvements not only in drillability and efficiency, but most importantly in process safety. Case histories on how MPD has performed will be presented on the following: • allowed drilling to reach target depth in rank wildcat deepwater wells that have formations prone to severe circulation losses and narrow mud weight windows; • increased drilling efficiency by minimizing non-productive time associated with downhole pressure-related problems and by allowing for the setting of deeper casing seats; • enhanced operational and process safety by allowing for immediate detection of kicks, losses and other critical downhole events. • provided riser gas mitigation capabilities that can detect a gas influx once it enters the drilling fluid stream, and not after it has already broken out above the rig blow-out preventers (BOPs).Cosan Ayan
The document summarizes a presentation on using wireline formation testing (WFT) to characterize reservoirs and reduce uncertainties. It discusses how WFT can be used to measure pressures, sample and analyze downhole fluids, conduct transient tests, and test in-situ stresses. The results from these WFT analyses can be integrated into reservoir modeling workflows and help understand properties like permeability, fluid contacts, and the safe drilling window. Advanced sensors and improved transient testing capabilities in new generation WFT tools are providing more downhole data to reduce risks in reservoir evaluation.
Coiled Tubing Real-Time Monitoring: A New Era of Well Intervention and Worko...
Coiled Tubing Real-Time Monitoring: A New Era of Well Intervention and Worko...Society of Petroleum Engineers
Coiled tubing is a unique fluid and tool conveyance means used to intervene throughout the entire well lifetime. Its flexibility of use is certainly one of the largest in the oil-and-gas industry, ranging from logging to stimulation to cleanout and even drilling. However, for the longest time, it was only seen as a rudimentary fluid conveyance system, despite its capability to service any well deviation.
With the development of instrumented tools for downhole point measurements and the use of fiber optics for distributed sensing, the recent advent of coiled tubing real-time monitoring has completely transformed this image. The access to live wellbore information—such as pressure, temperature, or flow—along with accurate depth control thanks to casing collar locator and gamma ray sensors have greatly enhanced fluid placement. Meanwhile, the ability to monitor the load, torque, and accelerations the bottomhole assembly is subjected to significantly improves the performance and possibility to use and manipulate downhole tools. Thanks to real-time monitoring, a whole new realm of optimization possibility was discovered.
This lecture describes the various real-time measurements that are available today during coiled tubing interventions and how they can be used to provide the industry with faster, safer, and more efficient operations while maximizing return on investment. A wide range of applications and examples will be discussed. Through them, one will be able to appreciate how coiled tubing has now entered a new era where the limits of operational optimization still have not been reached.

From Natural Language to Structured Solr Queries using LLMs
This talk draws on experimentation to enable AI applications with Solr. One important use case is to use AI for better accessibility and discoverability of the data: while User eXperience techniques, lexical search improvements, and data harmonization can take organizations to a good level of accessibility, a structural (or “cognitive” gap) remains between the data user needs and the data producer constraints.
That is where AI – and most importantly, Natural Language Processing and Large Language Model techniques – could make a difference. This natural language, conversational engine could facilitate access and usage of the data leveraging the semantics of any data source.
The objective of the presentation is to propose a technical approach and a way forward to achieve this goal.
The key concept is to enable users to express their search queries in natural language, which the LLM then enriches, interprets, and translates into structured queries based on the Solr index’s metadata.
This approach leverages the LLM’s ability to understand the nuances of natural language and the structure of documents within Apache Solr.
The LLM acts as an intermediary agent, offering a transparent experience to users automatically and potentially uncovering relevant documents that conventional search methods might overlook. The presentation will include the results of this experimental work, lessons learned, best practices, and the scope of future work that should improve the approach and make it production-ready.

Direct losses from downtime in 1 minute = $5-$10 thousand dollars. Reputation is priceless.
As part of the talk, we will consider the architectural strategies necessary for the development of highly loaded fintech solutions. We will focus on using queues and streaming to efficiently work and manage large amounts of data in real-time and to minimize latency.
We will focus special attention on the architectural patterns used in the design of the fintech system, microservices and event-driven architecture, which ensure scalability, fault tolerance, and consistency of the entire system.
Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

The typical problem in product engineering is not bad strategy, so much as “no strategy”. This leads to confusion, lack of motivation, and incoherent action. The next time you look for a strategy and find an empty space, instead of waiting for it to be filled, I will show you how to fill it in yourself. If you’re wrong, it forces a correction. If you’re right, it helps create focus. I’ll share how I’ve approached this in the past, both what works and lessons for what didn’t work so well.

GNSS spoofing via SDR (Criptored Talks 2024)
In the realm of cybersecurity, offensive security practices act as a critical shield. By simulating real-world attacks in a controlled environment, these techniques expose vulnerabilities before malicious actors can exploit them. This proactive approach allows manufacturers to identify and fix weaknesses, significantly enhancing system security.
This presentation delves into the development of a system designed to mimic Galileo's Open Service signal using software-defined radio (SDR) technology. We'll begin with a foundational overview of both Global Navigation Satellite Systems (GNSS) and the intricacies of digital signal processing.
The presentation culminates in a live demonstration. We'll showcase the manipulation of Galileo's Open Service pilot signal, simulating an attack on various software and hardware systems. This practical demonstration serves to highlight the potential consequences of unaddressed vulnerabilities, emphasizing the importance of offensive security practices in safeguarding critical infrastructure.

- 1. Transportforum 2012, January 11-12th Linköping NOx Abatement Technique for Marine Applications Improved SCR Systems Mathias Magnusson PhD Student Department of Shipping and Marine Technology Sustainable Ship Propulsion mathias.magnusson@chalmers.se 1
- 2. Outline • Background • Paper I:The influence of sulfur dioxide and water on the performance of a marine SCR catalyst - Method - Results and Concluding Remarks • Paper II: A system perspective on practical experiences of marine SCR installations - Method - Results and Concluding Remarks • Final concluding remarks and Outlook 2
- 3. Background • Environmental implications of NOx? - Eutrophication - Acidification - Contribution to ground level ozone - Contribution to secondary particulate matter (PM) • NOx emissions from shipping? - Global level: suggested that approx. 15% of all global anthropogenic NOx emissions originates from vessels, with approx. 70% occurring within 400 km of land. - European level: NOx emission from international shipping (EU) is projected to increase by 67% between 2000 and 2020 exceeding the total of all land-based sources in EU-25 in 2020. - Regional level: NOx emission from vessels in the Baltic Sea during 2007 ~ 122 ktones of nitrogen Sweden ~ 50 ktones of nitrogen. - Swedish level: In addition, EMEP 2011 suggests 20% by shipping 3
- 4. Background • Incentives and regulations for reduced NOx emission from shipping? - The Norwegian NOx fund and the Swedish environmentally differentiated fairway dues - IMO’s Revised MARPOL Annex VI – Reg. 13 Demand for NOx abatement technology! 4
- 5. Background • NOx abatement technologies - Primary (combustion); IEM, EGR, Water techniques, LNG… - Secondary (after-treatment); SCR • Selective Catalytic Reduction (SCR) 5
- 6. Method Paper I • The aim: investigate how sulfur, water and low temperatures affect an SCR - experimental flow reactor studies - commercial vanadia-based washcoated urea-SCR catalyst for marine applications ������������������������������������������������ ������������ ������������������ ������������������������ ������������ = ������������������������������������ ������������ ������������������ ������������������������������������������������ 6
- 7. Flow reactor studies on SCR-activity as a function of SO2-concentration 200 ppm SO2 ≈ 1 wt.% S Feed gas composition: 500 ppm NO, 500 ppm NH3, 8% O2 and 100- 1100 ppm SO2 (350oC and 12200 h-1) 7
- 8. Flow reactor studies on SCR-activity as a function of temperature (SO2 + H2O) Feed gas composition: 500 ppm NO, 500 ppm NH3, 8 % O2, 500 ppm SO2 and 4 % H2O (SV 6100 h-1 or 300oC) 8
- 9. Concluding Remarks Paper I • In general, the addition of SO2, in the absence of water, promotes NOx reduction and NH3 conversion along with increased formation of N2O Formation of new acid sites that improve NH3 adsorption? • In general, the addition of water, in the absence of SO2, decrease NOx reduction and NH3 conversion along with reduced formation of N2O Competitive adsorption on vanadia sites and reduced NH3 oxidation? • In general, in the presence of both SO2 and water, the activity for NOx reduction decreases at high concentrations of SO2 (>500 ppm) low temperatures (< 300oC) and high space velocities (> 12200 h-1) Complementary studies suggest formation of ammonium sulfates? 9
- 10. Method Paper II • The aim: identify important technical, human and organizational conditions necessary for safe, efficient and sustainable operations of SCR - Combination of focus group interviews (n=6+2) and individual interviews (n=5) - Theme: 1) Installation; newbuilding and retrofit, decision making, stakeholder communication 2) Operation, service and maintenance; usability, accessibility, manuals, support, outage 3) Knowledge and training; before and after installation, knowledge transfer 10

- 12. Practical experiences of marine SCR installation • Knowledge and training - SCR is complex, chemical reactions not well understood - SCR did not require any special training or knowledge, but some had arranged extra training for their crew. (Note: hundreds of systems and the SCR is not a safety-critical system!) - SCR suppliers are interested in improved training - Cargo owners supposed sufficient training – safe and efficient operation 12
- 13. Concluding Remarks Paper II • Clear and concise incentives are needed Regulations, customer demands or other commercial benefits? • Design and operational challenges Supply and quality of urea, urea-injection, exhaust gas composition due to various marine fuel and lubrication oils? • Lack of structure for training, development and transfer of knowledge of SCR (chemical and practical) Increased risk for occupational accidents and unnecessary harmful emissions to the environment? (Cost x 3) 13
- 14. Final Concluding Remarks and Outlook • SCR is a highly efficient NOx abatement technology, but… - …certain risks of deactivation, but may be avoided…(exhaust gas temperature, space velocity and sulfur concentrations) - …high overall efficiency requires appropriate and sufficient knowledge of how the system works and what the prerequisites are to achieve successful SCR operation • Outlook - Flow reactor experiments using different types of urea? - Flow reactor experiments with varying diesel exhaust gas compositions? 14
