Artificial lifts are used around the world in approximately 85% of the wells and its overall efficiency cannot be overestimated. The specific lift method for a particular application is largely accomplished by production engineers; they apply both field / operational experience, and modern knowledge. This quality has been recognized as a defect in most engineering disciplines and have led to sub-optimal design in projects. Improper selection of artificial lifts can lead to a reduction in production and a significant increase in operating costs. Once a decision is made about the type of lift that will be installed in a well, whether or not this method is chosen optimally for the existing conditions of the well; very little can be done after installation. This paper analyzed the selection criteria for various artificial lift techniques and illustrate why the selection made is the most suitable technique to be applied in that particular well condition. For optimum decision making, the study considered the characteristics of the reservoir, their operational and design characteristics, the location of the facility and the artificial lift system economic. The economic evaluation of each case was carried out taking into account the capital and operating cost for each option.
