When oil or gas is being produced the reservoir pressure reduces. At a certain point in time it can happen that the pressure in the reservoir becomes too low for production and artificial lift and pumping can be required. This course covers the natural flow and artificial lift, reservoir inflow and multiphase outflow, well performance characteristics, the gas lifts system and its four major components, well deliverability and gas injection ratio, comparison of continuous flow and intermitting lift, continuous flow operation, troubleshooting and optimization, gas lift design with unlimited gas and pressure, gas lift design with limited pressure and gas availability, start-up and surveillance procedures, prioritization of wells, and gas lift and pumping optimization. This course will enhance the participants’ knowledge, skills, and attitudes necessary to understand the gas lift and pumping and technologies specially the proper selection, operation and maintenance of subsurface pumps so the best economical life can be obtained.
