摘要： A hydrocarbon power system that includes a turbine generator, a downhole heat exchanger, and an expander pump assembly. Various arrangements of the expander pump assembly address considerations related to the design of the downhole expander pump. In such a system, the turbine generator receives a high pressure working fluid from the downhole system to drive a generator. The turbine generator can be in fluid communication with the downhole heat exchanger and with the turbine portion of a downhole turbine pump assembly. The pump portion of the downhole turbine pump assembly can be in fluid communication with the downhole heat exchanger and a source of hydrocarbon fluid.

摘要： A compressor free, generator free system production well for accelerated oil and gas removal from a reservoir using a magnetically coupled expander pump assembly, which include an outer expansion turbine that rotates around a pump. A magnetic coupling couples the expansion turbine to the pump. An inner portion of the magnetic coupling can be coupled to a pump shaft that drives the pump. An outer portion of the magnetic coupling can be driven by the expansion turbine, which rotates circumferentially around the pump. The expansion turbine drives the fluid to pump a driven fluid stream through the magnetic coupling. In this manner, flow directions of both driving and driven fluid streams remain separate and coaxial, thereby facilitating a reduction in an overall diameter of the expander pump assembly.
