Utilizing Nitrogen Lifting as an Alternative to Electrical Submersible Pumps in the Alaşehir Field, Turkey

Abstract

Geothermal wells that have experienced a decline in reservoir parameters, such as pressure, temperature, and non-condensable gases, are considered candidates for artificial lifting to compensate for the reduced production. Nitrogen lifting is a reliable gas injection method for production wells, serving as an alternative to Electrical Submersible Pumps (ESPs). This study presents the first successful application of nitrogen lifting in the Alaşehir geothermal field. Technical details of the nitrogen lifting are provided to offer valuable insights for geothermal operators. The advantages and risks associated with the demonstration are also discussed. It was found that nitrogen lifting offers certain advantages over downhole pumps in ensuring reliable production.
