Abstract

AbstractElectrical submersible pumps (ESPs) are a well-known artificial lift technology used in the oil and gas industry to enhance production. One of the major requirements to implement ESPs is the need for a rig to install or replace failed pumps frequently. Temporary rigless ESPs (TRL ESPs) are a new technology that is being developed and tested in many parts of the world. The main advantage of this technology is its much lower installation cost compared to the conventional ESPs because it is deployable through wireline. The main drawback of this technology is the low volumes of fluids it can lift from the wellbore compared to the conventional ESPs. Therefore, it is mainly used as a temporary replacement on top of a failed ESP awaiting a workover job. The feasibility and applicability of the utilization of such technology is studied in this paper using actual field data from more than 500 wells from two fields. The added value of using TRL ESPs is to supplement the lost production volumes from the wells with failed pumps during the waiting time for workover and hence reducing the number of needed backup wells. It was found that using TRL ESPs will reduce the number of needed backup wells over a three-year period by 17–25% based on the actual historical data. Overall, the main outcome of this study is the formulation and development of the predictive model and feasibility study of the TRL ESPs using the actual field data.
