PCP technology has progressed to enable their application in high temperature environments. Typically PCP elastomers limited the temperature range for operation to approximately 150C, but the recent introduction of metal to metal pumps has removed this ceiling. Operation above 150C also provided a challenge for the downhole gauges used to monitor the pump and well performance as downhole gauge electronics designed for PCP monitoring were also typically limited to around 150C operation.

This paper discusses the introduction of permanent high temperature gauges designed for application in steam flood wells lifted by PCP. The field trials revealed various challenges and hurdles which were overcome to design a monitoring system suitable for an extremely challenging operational environment. The paper details the operational environment, challenges encountered and successful deployment of gauges monitoring wells produced by PCP’s in temperatures above 400F.
