A New Approach to Artificial Lift Selection

When reservoir pressure is not sufficient to sustain the flow of oil to the surface at adequate rates, natural flow must be aided bye artificial lift. In fact artificial lift methods increase the well production long life. The decision of which artificial lift method to use is very important to the long-term profitability of the field. An improper selection of artificial lift can reduce production and increase the operating cost substantially. Once a decision has been made on the type to install on a well, it can be rarely altered whether or not the method selected was and still is the optimal for the existing conditions.This paper presents the screening criteria on the different artificial lift techniques and selection guide. Selection of artificial lift is based on production, reservoir and well constrains, produced fluid properties and surface infrastructures. To choose a appropriate method, we produce software with V.B.NET code. This software involves 28 parameters in various condition and be able to arrange methods according to best results
