Well Completion and Well Testing

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.

Geo-scientists, Engineers and Managers (in Drilling, Well Intervention/Services, Reservoir Engineering, Production Operations, Marketing/Sales etc.), whose jobs require them to interface with Completion Engineers, Production Technologists, Well Production Operations Engineers, and Well Maintenance/Servicing Engineers who wish to enhance their current job effectiveness, through more knowledge on Well Completion and Performance, than that attained from their own “core” discipline training and exposure
