Intermittent Gas Lift Application

About the Course

Intermittent gas lift is an artificial oil producing method, mostly applied on the low productivity wells at mature fields. The course provides the comprehensive knowledge for optimizing, designing and trouble analysis. The unique approach, developed through many years of practical work on intermittent gas lift application, leads to the development of powerful software suite called Glip (Gas Lift Intermittent Program) and it will be used during the course. The evaluation of problems in intermittent gas lift application is based on the recognition of symptoms sourced from two-pen chart diagrams. Simulation of downhole conditions is possible by using just information from two-pen diagram (casing and tubing pressure). The participants will be educated to perform full sensitivity analysis to define the optimum parameters (duration of cycle, number of cycle per day, gas injection rate, intermittent performance curve etc.) of intermittent gas lift operation.
