Abstract:
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.

Abstract:
A cryopump provides for high pumping speed of Type III gases. An open configuration of a frontal array provides high conductance of gases into a radiation shield which is shaped to focus gases toward a second stage array. The second stage array has an open configuration of baffles coated with adsorbent. Substantially all of the adsorbent has a direct line of sight to the radiation shield or to the opening in the radiation shield, and substantially all of the baffles are coated with adsorbent. In one form, the second stage cryopump array comprises an array of discs fanned to define a generally ball shaped envelope.

Abstract:
Provided herein are passive microfluidic pumps. The pumps can comprise a fluid inlet, an absorbent region, a resistive region fluidly connecting the fluid inlet and the absorbent region, and an evaporation barrier enclosing the resistive region, the absorbent region, or a combination thereof. The resistive region can comprise a first porous medium, and a fluidly non-conducting boundary defining a path for fluid flow through the first porous medium from the fluid inlet to the absorbent region. The absorbent region can comprise a fluidly non-conducting boundary defining a volume of a second porous medium sized to absorb a predetermined volume of fluid imbibed from the resistive region. The resistive region and the absorbent region can be configured to establish a capillary-driven fluid front advancing from the fluid inlet through the resistive region to the absorbent region when the fluid inlet is contacted with fluid.
