EXECUTIVE SUMMARY
Well Stimulation, Acidizing & Fractured Reservoir Modelling is an advanced professional training program focused on improving hydrocarbon production from complex reservoir systems. The course integrates well stimulation engineering, acid treatment design, hydraulic and natural fracture analysis, and fractured reservoir simulation. Participants examine reservoir damage mechanisms and identify technically appropriate stimulation strategies for different geological and production conditions. The program explains matrix acidizing, acid fracturing, fracture conductivity, fluid-rock interactions, and treatment placement principles. Particular emphasis is placed on naturally fractured reservoirs where conventional modelling assumptions may produce unreliable production forecasts. Participants learn to interpret reservoir, well test, pressure, geological, and production data for effective stimulation decisions. Practical exercises demonstrate how stimulation design variables influence injectivity, productivity, recovery, and long-term well performance. The course also addresses treatment risks, operational limitations, diagnostic methods, and post-stimulation performance evaluation. By completion, participants will be equipped to support technically sound stimulation programs and more reliable fractured reservoir development decisions.
INTRODUCTION
Declining well productivity and complex fracture networks present significant challenges for modern oil and gas developments. Effective well stimulation requires a detailed understanding of reservoir damage, rock properties, fluid behaviour, fracture characteristics, and well completion conditions. Acidizing can significantly restore or enhance production when treatment fluids, volumes, rates, and placement methods are properly selected. Fractured reservoirs require additional analysis because fluid movement occurs through interacting matrix blocks and natural fracture systems. Accurate fractured reservoir modelling is therefore essential for estimating flow behaviour and predicting treatment response. This course connects stimulation engineering with reservoir characterization and simulation to provide a complete decision-making framework. Participants evaluate matrix acidizing, acid fracturing, fracture modelling methods, and production response using integrated technical workflows. The learning approach combines engineering principles, practical calculations, case analysis, and treatment performance interpretation. The program enables professionals to make better stimulation and reservoir management decisions under technically challenging conditions.
