Steam-assisted gravity drainage (SAGD) and other thermal recovery applications require electrical submersible pump (ESP) equipment which can withstand extremely harsh oilfield environments with well conditions typically including high gas, sand, and scale concentrations in addition to the extreme temperatures and temperature cycles generated in the process.

Thermal recovery pump construction specifications were developed as part of a new tiered product line covering deployment of equipment in wells with bottom hole temperatures (BHT) as high as 250°C. Special construction considerations were implemented for stage compression, thrust handling, bearing design and materials of construction.

The new pump technology combines high temperature and abrasive handling features to extend product life and provide consistent reliability in thermal recovery applications. Enhanced temperature tolerance is achieved through reduced thermal stresses on internal components leading to better reliability and increased run life.

This next generation of thermal recovery pumps has been extensively field validated with systems utilizing the new technology currently installed and operating in over 400 wells.
