Well Completion & well testing

This short course places emphasis on the role of the Well, as part of the Integrated Production System. Well Completion design concepts and the technical selection criteria for the main completion components are reviewed in detail. Group exercises on Completion and Performance are also part of the learning process. The course also highlights the Operating Company’s viewpoint in the area of Well Completion and Well Production Management

By the end of the course, participants should be able to: State how Well Completion fits into the E&P Activity; Recall and discuss hydrocarbon exploitation considerations for well productivity and completion design; Describe the main parameters that influences Well Performance and Productivity; Describe the factors that influence the selection and design of the completion string and components; Carry out a completion design on the Onshore and explain how it will be run in the well, Type of well test, planning the test, Surface Equipment and downhole tools.

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.
