Successful hydrocarbon recovery optimisation rests on our ability to maximize remaining resources potential, identify profitable targets, optimize and design well locations for efficient reservoir drainage. The session will focus on advancements in pore and reservoir scale numerical simulation of complex physical phenomena of multiphase flow, CO2 flow and full field reservoir drainage. Development of novel workflow, methodology and solutions require exploration of novel approaches that involve generally available and physics-informed ML models. The authors collectively offer a multidimensional perspective on the evolving landscape of reservoir engineering and numerical simulation. The integration of advanced computational methods and data-driven insights showcased in this session paints a compelling picture of the future trajectory of reservoir management.
