ABSTRACT

This study examines an operator’s implementation of an integrated production management (IPM) system to navigate the complexities of its coal seam gas (CSG) gathering network and enhance commercial competitiveness. A key challenge in developing an integrated model from subsurface to delivery points is managing high well counts and complex reservoir and gathering system modelling. To address these challenges, we utilised multi-pressure type curves, simplifying the problem while preserving essential detail for optimised production. A major achievement was significantly reducing runtime compared to other tools, enabling more time for scenario exploration rather than model setup and execution. The developed model provides critical insights into network management options and their consequences during major operational events, such as maintenance shutdowns or integrating new well clusters. Validation with actual measurements yielded promising results, demonstrating the system’s ability to accurately forecast gas availability at delivery points. This improved understanding allowed the operator to optimise operations and maintain a reliable gas supply, strengthening market competitiveness. Integrating reservoir modelling, well management, and surface facility optimisation within the IPM framework streamlines operations and enhances decision-making for better economic outcomes. The findings highlight the importance of such systems in overcoming modern gas production network complexities and supporting the company’s ability to maintain and enhance its competitive position.
