Today, Carbon Capture, Utilisation and Storage (CCUS) is widely recognised as one of the key tools in mitigating climate change towards a net-zero carbon future. Due to the slow pace in the development of carbon pricing mechanisms, a major conundrum for Carbon Capture and Storage (CCS) projects is the recurring theme of regulating the project cost while maintaining safety and integrity. For a CCS project to be deployed successfully, it is vital that engineers have access to models that accurately capture CO2-rich fluid phase behaviour and thermodynamics, multiphase flow behaviour and other flow assurance aspects.

This session on CO2 flow assurance in the context of CCS aims to provide a comprehensive overview of the key considerations involved in the safe and efficient transportation of CO2 from capture to storage locations. The session will cover various topics including:

• Modelling CO2-rich systems with undersaturated water and its influence on fluid phase behaviour, hydrate formation, CO2 solubility in brine, the effect of impurities in it, and other factors.
• Explore the challenges and considerations involved in CO2 multiphase flow while transporting from capture to injection sites. As CO2 can exist in gas, liquid, and in supercritical forms during transportation, modelling the phase transition can be crucial for ensuring the stability and safety of the system.
• Evaluate concern on corrosion while transporting CO2.
• CO2 flow assurance design and operability strategy to improve project feasibility, reduce complexity, and enhance cost optimisation.

Identification of petroleum reservoir fluid types, behaviour, characterisation and risk assessment of flow assurance and production chemistry aspects are the critical factors in many of the decisions that must be made in fluids production based on the holistic view of six lenses, namely from reservoir, wells, surface, transportation, terminal and up to export sales. Therefore, reservoir fluid properties will play a key role in the design and optimisation of injection and production strategies as well as surface facilities for efficient reservoir management.

This session will discuss and explore fluid chemistries and compositions that have a significant impact on flow assurance, including:  

• The importance of fluids chemistry in hydrocarbon exploitation.  
• Groundbreaking technology capable of identifying and characterising fluid chemistries in the deepwater environment.
• Advanced fluid sampling, testing, characterisation, and application for process stimulations.
• Geochemistry applications in fluid characterisation.
• Programme, tools and/or a system that can determine fluid uncertainties with respect to flow assurance.
• Case history, lessons learnt and industry best practices on managing the changes in fluid chemistries.

As offshore oil and gas developments move into deeper waters with harsher environments, technological challenges exist for operators and offshore engineering service providers.  This session will review and discuss novel technologies that can provide a cost-effective development plan and ensure a safe and stable operation, including:

• Various emerging technologies in the deepwater environment.
• System integration between oil gas subsea umbilicals, risers flowlines (SURF) and topside systems.
• Long-distance subsea tiebacks.

Liquid handling and solids management are among the most prevalent flow assurance issues present in both oil and gas production. This is further exacerbated in deepwater developments, flow assurance critical fields, and late-life operations. If left unattended, they are one of the main causes of production disruptions that could lead to serious HSE risks during operations and have the potential to shut in and/or even lose oil and gas assets. Liquid handling and solids production are onerous to operations and often leave operations debilitated if systematic and holistic mitigation and remediation strategies are not in place. The balance between CAPEX, OPEX, and risk needs to be evaluated with a good understanding of these inevitable issues and their implications.

This session will discuss the various flow assurance analysis, methodologies, lessons learnt, best practices, and available technologies required to ensure continuous and uninterrupted production whilst safely and efficiently managing liquids and solids production.

This session will focus on how to accurately predict the behaviour and quantitative prediction of contaminants such as Carbon Dioxide (CO2), Hydrogen Sulfide (H2S), Mercury (Hg), Nitrogen (N2), Water (H20), and other impurities concentration in reservoir fluids through reliable process engineering applications and design of mitigation strategies to reduce the potential risk of contaminations. The session will also explore the sampling technologies of multiphase systems and the application of online analysers for predicting contaminant behaviour.
