Development of Natural Gas Field Producer

This course is a theoretical-practical course designed to address the basic three stages in a gas field’s life: Reserves Determination, Development and Operation of the gas field. Before planning development of an optimum producing gas field, it is necessary to determine the total reserves of the gas field as accurate as possible. After this first step, It is necessary to determine the number of wells to develop the field based on the Gas Reserves, Reservoir Pressure, Reservoir fluids and Rock Properties, Gas Reservoir Dominant Mechanisms and Gas Demand.

    16 General Discussion and Conclusions

This training course uses both conventional and non-traditional techniques. It utilises small group and facilitated plenary discussions as well as instruction to explore key concepts, models, tools and techniques. Hands-on exercises and case studies are used to practice the application of knowledge and use of skills. Structured reviews provide the opportunity to consider how the learning can be applied to the delegates’ own work.
