Moderator: Dang Ngoc Quy, Vice President, PetroVietnam Exploration Production Corporation

In today’s energy transition, the development of gas fields faces increasing complexity due to environmental, economic, and technical challenges. As natural gas continues to serve as a bridge fuel, operators must navigate the depletion of conventional resources while focusing on more difficult plays, such as unconventional, marginal, and stranded fields. These fields often present high levels of contaminants and demand advanced technologies to maximise production efficiency. Best practices in gas field development now focus on integrating innovative cost-effective technologies, emission control strategies, and regulatory frameworks that incentivise investment. By leveraging these approaches, stakeholders can unlock greater value, ensure sustainable production, and help meet the growing global energy demand.

This session will explore key strategies for managing gas assets, focusing on both surface and subsurface aspects to maximise the value of natural gas resources. On the subsurface side, effective reservoir management is crucial, particularly when addressing challenges such as varying CO₂ levels across multi-stack reservoirs. Strategic gas blending and the conservation of low-CO₂ gas sources are necessary to meet processing requirements and maintain production levels. Additionally, new approaches, such as machine learning, can enhance the prediction of changes in the condensate-to-gas ratio (CGR), supplementing traditional methods for managing gas-condensate fields. Well intervention programmes are also an important part of sustaining production, particularly in regions with limited access during certain seasons.

On the surface, the focus will be on maintaining and optimising offshore gas processing facilities and ensuring efficient operations, even with variability in gas streams. Integrating these strategies allows operators to extend the productive life of gas fields while maintaining economic viability and safety.

By leveraging best practices, modern technologies, and careful planning, this session will provide valuable insights into achieving sustainable performance in gas field management. It addresses the challenges of CO₂ management, seasonal intervention planning, and the application of innovative solutions to meet the evolving needs of the industry.

This session will explore best practices for developing high-contaminant reservoir fluids, Slimhole drilling techniques, and enhancing well productivity in high-pressure, high-temperature (HPHT) gas fields. Marginal and small gas fields with high contaminants require tailored approaches, including proper data acquisition, a fit-for-purpose development strategy for both subsurface completion and surface facilities, and innovative gas management strategies.

Slimhole drilling offers a cost-effective solution, reducing both drilling time and operational costs, particularly in smaller or marginal gas reservoirs. However, it also presents technical challenges, such as wellbore stability and equipment limitations. In HPHT environments, extreme pressures and temperatures further complicate drilling and well completion, requiring specialised materials, fluid designs, and advanced technologies. This session will address innovative solutions and best practices to overcome these challenges, improving safety, efficiency, and overall project outcomes.
