Design, Diagnosis and Optimization of Gas Lift Systems

This course is intended to familiarize production personnel with the use, basic principles, selection of the equipment, types, design, monitoring, etc, of a continuous and intermittent gas lift system. Engineers will obtain the basic skills to the analysis and design of any artificial lift system by using a continuous or intermittent gas flow rate. The description in details of certain technical aspects will allow engineers propose solutions in a rapid and save way in order to either increase or optimize the production of an oil well. Throughout the course, participants will solve practical examples.
