Abstract One of the mayor economical impacts in a Project of artificial lift system shift is the associated cost of energy moreover the maintenance and well intervention must be considered. These variables are reflected as addition on the final artificial lift cost selected. This study was accomplished based on experience at the Teca and Nare fields operated by Omimex Colombia where an artificial lift system shift was performed from Rod Pump (RP) into Progressive Cavity Pump (PCP), achieving significant savings in well downtime and energy comsuption at the same volume of production. The strategy to develop this project started with the identification of well candidates where steam injection was not feasible then a change on the artifitial lift system was proposed to a set of wells. Also is highlighted the importance of the operational variables in long term at the moment to choose an artifitial lift system
